Forefront TMG 2010 has been built on top of the core capabilities delivered in Microsoft Internet Security and Acceleration (ISA) Server 2004/2006 in order to deliver a comprehensive, enhanced and integrated network security gateway. Forefront TMG provide additional protection capabilities to help secure the corporate network from external/Internet-based threats. Forefront TMG 2010 prevent abuse of networks from internal and external entity. Forefront provide more management capabilities in terms security and protection. Forefront TMG 2010 is available in Standard Edition and Enterprise Edition. Standard version does not support Array/NLB/CARP support and Enterprise Management. For E-mail Protection both version requires Exchange license.
Forefront TMG 2010 provide the following enhanced protection capabilities:
Understanding Network Topology
The following Forefront TMG network topologies are available:
- Edge firewall—In this topology, Forefront TMG is located at the network edge, where it serves as the organization’s edge firewall, and is connected to two networks: the internal network and the external network (usually the Internet).
- 3-Leg perimeter—This topology implements a perimeter (DMZ) network. Forefront TMG is connected to at least three physical networks: the internal network, one or more perimeter networks and the external network.
- Back firewall—In this topology, Forefront TMG is located at the network’s back-end. Use this topology when another network element, such as a perimeter network or an edge security device, is located between Forefront TMG and the external network. Forefront TMG is connected to the internal network and to the network element in front of it.
- Single network adapter—This topology enables limited Forefront TMG functionality. In this topology, Forefront TMG is connected to one network only, either the internal network or a perimeter network. Typically, you would use this configuration when Forefront TMG is located in the internal corporate network or in a perimeter network, and another firewall is located at the edge, protecting corporate resources from the Internet.
Functionality of a single network adapter topology
The single network adapter topology enables limited Forefront TMG functionality, that includes:
- Forward (CERN) proxy for HTTP, HTTPS, and CERN proxy FTP (download only).
- Web caching for HTTP and CERN proxy FTP.
- Web publishing. HTTP-based communications, such as Microsoft Office SharePoint Server, Exchange Outlook Web Access 2007, ActiveSync®, and remote procedure call (RPC) over HTTP (Outlook Anywhere, Terminal Services Gateway or WSMAN-based traffic).
- Dial-in client virtual private network (VPN) access.
Limitations of a single network adapter topology
The following limitations apply when you use the single network adapter topology:
- Server publishing and site-to-site VPN are not supported.
- SecureNAT and Forefront TMG Client traffic are not supported.
- Access rules must be configured with source addresses that use only internal IP addresses.
- Firewall policies must not refer to the external network.
Hardware Requirements
Systems requirements depends on number of users and deployment scenario. Forefront TMG is a vital part in a ICT infrastructure. To achieve best performance, you must add best processing power and memory in TMG server however the following will give you an optimum performance.
Processor- Intel Xeon (Dual core/Quad-core/i7) or AMD Opteron (dual core/quad core). Intel Hyper-Threading Technology enabled in bios if Intel server board.
RAM-8GB
Disk Space –50GB systems partitions and 150GB logging +60GB-100GB Web caching in a separate partition. RAID 5 config would be highly recommended.
NIC- 2 Gigabit NIC with redundant config (number of NICs depends on deployment scenario)
Important! Forefront TMG has been built on 64 architecture.
Operating Systems and features
Windows Server 2008 SP2 64 bit or Windows Server 2008 R2
Microsoft .NET Framework 3.5 SP1
Windows Web Services API
Network Policy Server.
Routing and Remote Access Services.
Active Directory Lightweight Directory Services Tools.
Network Load Balancing Tools.
Windows Power Shell
Windows Installer 4.5
Important! It’s not recommended to install any application or programme in TMG server other then antivirus program. It must be a dedicated server for Forefront TMG. Disable unnecessary services after installing operating systems. Install Machine Certificate from Enterprise Root CA Authority before installing TMG. TMG server must be a member of Active Directory Domain.
Installation of Forefront TMG
Prepare a 64 bit Windows Server 2008. Insert Forefront TMG DVD into the server. Run preparation tools.
Click continue on UAC authorization prompt.
Check Launch TMG installation. Click finish.
Add ranges of internal IP address For example: 10.10.10.1 to 10.10.10.255. You can as many subnet ranges as you have for internal networks.
Open Forefront TMG Management from start menu. TMG will automatically prompt you for initial configuration.
Step1: Network Setup Wizard—Use to configure network adapters on the server. Network adapters are associated with a unique Forefront TMG network. Note that you must have static IP address in all NIC of TMG server before you proceed for network settings.
This is highly important part of config because in this section you will mention what type of network topology you are going to use. Here, I am configuring De-militarized Zone (DMZ) or 3-Leg Perimeter. You have to select your desired config.
In this section, you have to select the behaviour of the traffic among internal, perimeter (DMZ) and external network. For example, My Forefront TMG 2010 server has been configured to route between internal and perimeter and NAT in between perimeter and external as I choose private networks in perimeter. So that I can hide IP addresses of my perimeter networks.
Step2: System Configuration Wizard—Use to configure operating system settings, such as computer name information and domain or workgroup settings
Step3: Deployment Wizard—Use to configure malware protection for Web traffic, and to join the customer feedback program and telemetry service.
Networks, Proxy and Update Configuration
Open Forefront TMG Management. On the left hand pan, Select Update Centre. Click configure settings on task pan. Set update policy. If you have Windows Server Update Services (WSUS) then you may select WSUS or use Microsoft update services.
Select networking>Select Networks Tab>Double click on Internal. You will be presented with Internal Properties. Configure all the tabs as shown below.
In the domain tab, add internal domain(s). For example: *.wolverine.com.au
In the web browser tab, check Bypass Proxy… and Directly Access….
Verify all your internal IP addresses you added during installation. In this window you can add more internal IP addresses if you want.
Check Publish Automatic Discovery information for the network and use port 80 as default.
In Forefront TMG Client settings, Check Enable Forefront TMG client support for this network. un-check Automatically detect settings and Use automatic scripts.., Check Use a Web proxy server
In the Web Proxy Tab, Enable HTTP and use port 80 as default. However, you can use port 8080 if you want. Click on authentication and check integrated. Click on advanced and check unlimited. Now Apply and ok.
Apply changes.
Now repeat all these config for perimeter networks as you did for internal networks.
Connecting Active Directory, DNS and DHCP
Setup connectivity with Microsoft Active Directory, DNS and DHCP. Click on monitoring>click connectivity verifiers>Click Create New Connectivity Verifier. Create connectivity for Active Directory, DNS and DHCP.
Click Next and Finish. Repeat it for DNS and DHCP. If you have a upstream Proxy, connect to upstream proxy using similar method.
Create HTTP and HTTPS rule
By default all access rules are denied. Now Create web access rules for internal networks allowing HTTP and HTTPs traffic pass through from internal network to external and perimeter. Also allow HTTP and HTTPs traffic pass through from perimeter to external and internal. Click Firewall Policy>Click Create Access Rule on Task Pan.
Test Forefront TMG Setup
Now moment of truth. Log on to a computer using domain user credential in any internal network. Setup proxy in IE connections and browse internet.
Thumps UP.
Remote Management Console Installation
Forefront TMG is 64 bit but downloadable 32 bit TMG Admin Console available on this Microsoft link
Insert the Forefront TMG DVD into the DVD drive, or run autorun.hta from the shared network drive.
On the main setup page, click Run Installation Wizard.
On the Installation Type page, select Forefront TMG Management only.
On the Installation Path page, you can change the default installation path.

Great work, Thanks for posting.
How do we configure Multiple TMG servers For redundency?
For redundency does both TMG servers needs to be joined in AD?
Hello Mohsin,
You need TMG enterprize version. Once you configured primary TMG server. Then install second one, at the begining of installation it will ask you to join with another TMG Array or configuration and storage…. Once join the array, it will get all the config.
Both TMG servers must join ADDS. Otherwise you will not be able to install certificates and configure integrated authentication for internal network.

i have forefront tmg install but my reports comes with IP addresses,but i want the reports to come with user name from my active directory
Hello Samuel,
TMG user activity report is a feature available in TMG SP1. Install SP1 using http://microsoftguru.com.au/2010/08/07/install-forefront-tmg-sp1/
Go to Logs and Report>Task pan> you will see user activity report. Before you do that you must connect TMG to AD using conectivity varifier and set integrated authentication.
Regards,
Raihan
yeah i have the verifier for AD and SP1 but still i see empty reports for user names but i get the reports for IP Addresses
I am not clear about your question. What report you want to see?
i just want to ask about something ,,
how did u do your configuration NICS ? i mean u did something a bit wierd . (at least for me )
your DNS in same range of internal Network , isnt suppose to be in same perimeter network range ?
another question .. how i can build my DMZ network with 2 internal network ?
the ips of inetnal network are 192.168.1.0/24
the other one is 192.168.2.0/24
what ip should i put to internal NIC ??
Ty
Hello Sami,
Screenshots are based on test platform. In real life, 3-leg perimeter/DMZ or Back to back DMZ, internal NIC of TMG points internal DNS server and external NIC of TMG point public DNS server if it’s single server 3 leg perimeter. But if it’s back to back then it should be like my new blog http://microsoftguru.com.au/2010/06/17/how-to-configure-back-to-back-firewall-with-perimeter-dmz-topology-step-by-step-guide/
If you can send me your network layout then I can advise with specific info.
192.168.1.0/24 and 192.168.2.0/24 should be added in the internal network range of TMG. TMG will still have one nic in the internal side not two internal nic. You need to add vlan in layer3 switch or core switch. Please send me details of internal, perimeter and external IPs and layout. Then I advise, you can put x @the end of IP if you dont want to disclose.
thanx a lot
Thanks Raihan
Hi,
I have the following layout:
10.0.1.x as the internal lan,
and eg. 4.4.4.x as the external lan.
Now i have a hyperv host that hosts virtual machine for clients, those get 4.4.4.x range. Our internal machines (scvmm, sql, web, internal ad) etc all have 10.0.1.x ips.
We also have external AD/dns for our virtual machine clients, hosted on 4.4.4.x net.
Where should i put my TMG server? I would like to monitor the traffic from the virtual machines etc too, so i guess they need to go through the TMG as well.
Suggestions?
Peter,
First I dont understand what you mean by external LAN. Are you talking about external network or you have a 2nd site that you represent external lan? If you clarify these two then I give you right answer for you. whats sort of vm you hosting in hyperv?
But my guess#1: TMG for two different sites follow my new blog http://microsoftguru.com.au/2010/08/24/how-to-configure-site-to-site-vpn-using-forefront-tmg-2010/ in this situation you can put ad/dns/web in second sites and monitor and obtain report from both sites. Your hyperv must physically connecting to that 4.4.4.x vlan so that you add vm to that network.
Guess#2: Create a DMZ network for external client (in your language external lan) and placing all of them in that vlan. answer is back to back dmz or 3-leg perimeter. http://microsoftguru.com.au/2010/06/17/how-to-configure-back-to-back-firewall-with-perimeter-dmz-topology-step-by-step-guide/
If my guess is wrong then clarify those I mention earlier then I will provide perfect answer.
Hi,
Thanks for your feedback. Sorry for being unclear about the setup, i’ll clarify here:
We have 3 physical servers.
1: Hyperv host contains:
- AD01/DNS Internal 10.0.1.10
- AD01/DNS Public 4.4.4.2
2: Hyperv host contains:
- AD02/DNS Internal 10.0.1.11
- AD01/DNS Public 4.4.4.3
- SQL Internal 10.0.1.12
- WEB Internal 10.0.1.13 (needs access from internet)
- API Internal 10.0.1.14 (needs access from internet)
- SQL Internal 10.0.1.15
3. Hyperv host containrs:
- Purely virtual servers on 4.4.4.x (these are the customers’ virtual machines whihch needs to be accessible from the outside using RDP etc)
So basically, what i was thinking to setup is that the customer virtual servers are added to the AD0X public, and all our internal servers are added to AD0X internal. However, the Web and the Api (and maybe others in the future) needs to have an open port 80 from the internet on a public ip, since the web contains our homepage etc, and the api should be accessible from the internet too.
How would we set this up using TMG? Or should we do a different setup alltogether?
Thank you.
Peter
In your scenario, few things going on. 1.TMG Config 2. Publishing Web 3. RDP from extranet
Step1: Create DMZ—Place all 10.0.1.x in Internal Network, Place all 4.4.4.x in the DMZ network as you want customer to access. This is for security reason. You dont want your customer to access your internal network. http://microsoftguru.com.au/2010/06/17/how-to-configure-back-to-back-firewall-with-perimeter-dmz-topology-step-by-step-guide/ You may use 3-leg perimeter also.
Step2: Publish internal web server, API using reverse proxy functionality of TMG (Extranet client access internal web) http://microsoftguru.com.au/2010/08/08/how-to-configure-reverse-proxy-using-forefront-tmg-2010-step-by-step/
Step3: Create Terminal Services Gateway using Win2k8 TS (Extranet client will be able to do RDP to internal network). Allow RDP port in Router and TMG. download.microsoft.com/…/WS08TSGatewayServerStep-By-StepSetupGuide_En.doc
Hi again,
I’m a little bit unclear about the third point: “(Extranet client will be able to do RDP to internal network).”. I dont want our customers to be able to access our internal network, only their vps, eg 4.4.4.5. I also want to be able to access my internal servers from the internet, how do i do this? using vpn of some sort?
Sorry i forgot to ask about this:
Do we need the 2 internal AD servers and the 2 public AD servers? or can the perimeter network use the internal AD servers? If this is too much for the comment section, please leave me an email and we’ll talk $$$ for you to help us with the setup.
Hi Peter,
You dont need 2 AD server. If your internal DNS is ok for perimeter network. OK. if you dont want allow RDP then you can block it via TMG. type Public DNS or ISP DNS server IP in the external NIC of TMG server. You can email me on araberuni@hotmail.com for further help. Email me your visio diagram. Lets start from there. Let me know your location. I am on WST, Australia.

Raihan
Hi,
I am trying to setup TMG with a single network adapter, I am having lots of problems, does anyone have a step by step installation for this type of configuration.
Thanks in advance,
Everything same as you see in the config other then two. 1) you just have one nic. 2) Select TMG server on left hand pan>Right hand side task pan, click Launch Gettting Started Wizard>Click Configure Network Settings>CLick Next>Select single network adapter> follow rest of the config.
By the way what problems you having? visit http://microsoftguru.com.au for more TMG config.
Thanks Raihan,
I will be installing the TMG in the DMZ with a single NIC, I do not have access to AD to authenticate the user and no copy of AD is available in the DMZ.
What would be the best options, we already have a CISCO VPN and access to OWA once authenticated, but users do not want to logon twice to access their e-mail.
Thanks again for your help…
see the steps DNS configuration for DMZ network mentioned in my blog http://microsoftguru.com.au/2010/09/01/configure-3-leg-perimeter-dmz-using-forefront-tmg-2010-step-by-step/ and DNS config for perimeter is here http://microsoftguru.com.au/2010/06/17/how-to-configure-back-to-back-firewall-with-perimeter-dmz-topology-step-by-step-guide/
Use integrated authentication in TMG. your user need not log on again. Hope that fix this issue.
Hello Raihan,
First of all, thank you very much for sharing your knowledge through your website. It helped a lot to install and configure Frorefront TMG properly. It works finally even with the web site filtering. I installed Forefront on a testing environnement I chose the back Firewall option which suits our architecture. However, I would like to filter specific URLs, but unless I’m mistaken with Forefront you only can set up a strategy within the framework of Forefront Microsoft startegy. Is there any chance to create our own startegy to filter some websites?
Thank you in avance for your help.

Hello,
Sorry to bother you Raihan. As I explained 2 weeks ago I installed Forefront TMG 2010 in a testing environment. I chose the the back firewall topology which requires 2 NICs. The installation worked perfectly thanks to your tutorial. However, I haveone question is there any means to change the back firewall topology into Single Network Adapter one? Or does it need the complete reinstallation of Forefront TMG to do that?
Hope my question is clear enough.
Regards,
Thanks for your help again.

i just installed TMG in my Network, and i have one question about Inspection settings. there is i think last option “Block archive files if unpacked content if larger than (MB).” lets say restriction is set to 40 mb. when the user tries to copy 100 mb, tmg will throw a window that this user cant copy this file because of restriction…. is it possible to edit this error message…?
proxy error pages are editable. i found those html files and edited it… in this case if it is possible where to find it?
Right click on denial rules>property>Action>Advanced>Set custom redirected URL

Please,
I have install forefront TMG with the ip 10.61.1.76 using single NIC .i have about 20 branches that connect to the forefront TMG as a proxy server at the head office for internet access.
Been working fine for some time now for all 20 branches. Suddenly some branch cannot get access to the internet with the forefront TMG set in the IE as proxy server. It is happening randomly. A branch that could not work at a certain time will work at other time.
I captured the logging from one branch pc with the ip 10.61.7.17
Below is the log
Denied Connection
Log type: firewall
Status: A non-SYN packet was dropped because it was sent bya source that does not have an established connection with the forefront TMG computer.
Rule: none-see result code
Source:internal(10.61.7.17:1481)
Destination:local host (10.61.1.76:8080)
Protocol:HTTP proxy
Will be very happy if you can help me fix this problem. Been working on to fix it for three week with no results.PLEASE HELP.SOS
There are always dropped packets constantly. It does not mean anything is wrong.
The SYN error means exactly what it says. All connections begi with a SYN packet followed by an ACK packet being sent back the other way,…then the regular data portion of the session begins after that. The error is just saying something is trying to communicated with data (non-syn) packets without the connection first being established.
You have virus/spyware infected machines in those branches. Most of these types of infections cannot be totally removed with AV or Anti-spyware tools. They get embeded in the user’s profile,…so first do a cleanup with AV or ASpy tools,…then you have to backup the MyDocs, files on Desktop, Favorites, ect,…then delete the user profile,…create a clean one,…copy the saved files back into it. Repeat for every user that has a profile ont he machine.
Clean install windows. Update service pack, run malware removal tools. add signature blocking rule and block conficker,blaster, worm, spyware etc..
ok,thank very much. i will do what you just told me and get back to you.
i want to install fr TMG in SBS 2008 64 bit OS.

please explain more. What type of web sites? sharepoint, exchange or ordinary IIS. Did you add cname? external>internal or just for intranet.
Salaam Raihan,
I have exported fully functional ISA SE 2006 to newly installed Forefront TMG EE on server 2008 (as per standard requirment of TMG), after importing the configuration, i am not not to access my OWA and Intranet Site.
New TMG server got same fqdn and ip of ISA server or everything new. Did you imported certificates from previous ISA server to New TMG. Check IP addresses of external nic of TMG server that configured correctly. Check port forwarding for 443 to TMG server. Do you browse internet behind new TMG server.
Get back to me when you finish checking all these.
Salam Raihan,
We just want to upgrade ISA 2006 to TMG 2010 (not inplace). ISA server is single network. We want to upgrade with the same IP and the same NETBIOS.
Could you tell us step by step how to upgrade?
You will have a down time.
Step1: Complete Backup ISA 2006 and Shutdown
Step2: Build Win2k8 Server and Join domain using same name and IP
Step3:Install TMG http://microsoftguru.com.au/2010/03/08/forefront-tmg-2010-how-to-install-and-configure-forefront-tmg-2010-step-by-step/

Dear Raihan,
You did a GREAT job here. Congratulations.
Now and 3 days i’m experiencing a problem here. My Forefront server started blocking all incoming Replies to our messages. actually when we send a message and they reply on it. All the rest seems working ok. I haven’t made any changes on any setting. Do you know why it started doing this?
Thank you in advance
Victor
Hello Victor,
As you said, you havent made any changes, still I would suggest check your firewall rules again whether anything added or not. Did you applied any patch on server or TMG. Install TMG SP1 and see how it goes. Do you see any event in event log? install service pack on server and tmg. let me know.

Single network adapter is not a good idea. If you tell me the purpose or design of network then I can advise more specific to your your need.
Is it possible to have 1 upstream proxy with 2 sets of credentials and even tie in with Security Groups? ie. Admins have an ‘unfiltered’ username and password and Staff have ‘filtered’ ?
Cheers, Aaron
Yes you can configure that way.
I would appreciate some help with this please?
Dear Raihan,
Thank you for your reply,
I need the TMG to publish only the OWA exchange,
regards,
Tarek
To publish OWA you need to configure either reverse proxy or DMZ. see more http://microsoftguru.com.au/2010/05/28/exchange-2010-deployment-in-different-firewall-scenario/
You can do it through single nic thats not enough secure. Configure Edge or 3-leg perimeter using TMG

really good support
Salam dear,
i have installed an infrastrcture with the new TMG 2010 . the existant infrastructure already had an ISA 2000 and a “network behind network” , the remote one is a remote office wish access the LAN trough and leased line directly connected to the LAN switch .
here’s a simplified diagram :
(Remote office : 110.100.100.x )—–leasedline———–|(LAN :100.100.100.X)
| servers and, client have DefaultGateway 100.100.100.201
|
(Internet) =============(TMG:100.100.100.201)=|
the hole thing works great with isa 2000 client from 110.100.100.x was able to access servers directly. we changed the ISA 2000 with the new TMG et everything goes wrong .
we are able to do a ping from 100.100.100.X to 110… but anaything else wont pass , and i see a lot of a non-sync packet dropped ….message in the realtime report .
all the routing information are correct both in clients and TMG ,all networks are correctly defined as pretected network with the good routing rule in the TMG console .
i tried the one ” http://blogs.technet.com/b/sbs/archive/2007/11/29/network-behind-a-network.aspx” but it dose not solved the problem .
i m looking for anything to do . any ideas are welcom .
thanks in advance .
I am ready to help but you need to help me explain your config. If the diagram shows in the url is same in office. Then you should do things a bit differently. What type of topology you are using in TMG? Eg, Edge, Back firewall, Single NIC etc. As you mentioned TMG as your default gateway. I reckon , you are using Edge Firewall.
Step1: Create Site to Site VPN using your Router/Cisco 877/Modem between Site HQ & remote site
Step2: Route IP 110.100.100.x to 100.100.100.x and vise-versa
Step3: Place TMG behind the Router in Site HQ
Step4: Configure Edge Firewall in TMG & Add both IPs in the internet network of TMG
Step5: Allow Policy for Routing, Ping, DNS, DHCP between both IP ranges in TMG
Step5: Allow Http & Https
You are good to go. If you have two sites and TMG configured single nIC as shown in your URL. This might not work properly. By default TMG block everything, you need to open ports one by one whatever your need is. Please let me how you going.

Did you add connection verifier with AD DS?
Di you publish that url in TMG you are trying to access?
By default TMG block everything unless you define it.
Hi great article. It was my guide when I set up my TMG server.
.
But I’m having troubles with it, can you give a little help
I’m trying to setup the following.
The TMG server has 4 networks. It will be my only router in my infrastructure,so it should be able to route between networks.
1 – ISP (public IP)
2 – DMZ (192.168.101.91/24)
3 – Internal Clients(192.168.1.1/24)
4 – Internal Servers (192.168.7.101/24)
During the initial configuration I had setup 3-leg topology and there I listed the first 3 network adapters with the idea to add the fourth later.
So I went to networks and added new Internal network Named Internal Server network and added IP range for my servers subnet.
The problem is that in my routing table keeps “auto adding” persistent route for server network:
192.168.7.0 255.255.255.255 192.168.7.101. And this is cousing my server network to not be able to be routed via TMG.
I looked everywhere even compare Client internal and server internal but I couldn’t find any difference but the route keeps adding itself.Tried to deleted it but without success. I couldn’t find some dependency which couse it to “auto add” itself…
Is it adding in TMG server or your separate server? TMG must not auto add persistant routing unless you specified separate routing rules in TMG. Please explaina bit
Hello Raihan,
i have installed a new forefront tmg 2010,but i am not able to PING or do a remote desktop the server from my workstation.please help me to fix this problem,thank you
Check RDP services started and automatic
Check Remote administration Allowed in Windows firewall
Check RDP allowed in remote settings
Publish rules in TMG allowing rdp to the server from internal network
Telnet Servername 3389 (check port is listening)
Restart TMG server
Let me know how it goes.
Thanks, its working now ,i had to create a rule (allow all outbound from :internal,localhost to: external,localhost) before it worked.The reason why i reinstalled my forefront tmg is not solved.
i have 23 branches with different subnets,
10.61.2.0
10.61.3.0
10.61.4.0
..
10.60.23.0
My forefront TMG is on 10.61.2.0 subnet
and the defaults gateway is 10.61.2.251.
so i have my routing in the forefront as
Network Destination:10.61.0.0
Netmask:255.255.0.0
Gateway:10.61.2.251
metric:1
All the pc in the networks uses the forefront tmg as proxy.
All the pc`s on the subnet 10.61.2.0 are able to access the internet at all times
but although the other subnets too can get access to the internet but is not all the times.its off and on.it will work for awhile and the next minute will go off.
I have been having this problem of a while
please help me .this is my 3 forefront tmg i have installed just to solve this problem .please i really need help

Dear Raihan,
I want to use two different internet connections together from different ISPs.
ADSL and Satellite.
ADSL used manual proxy and Satellite used no proxy.
Can I do that in ISA 2006 or TMG 2010?
How to configure it. please help me.
Thanks.
I am a newbie in networking.
Can I use loadbalancing on the ISA 2006 with ADSL manual proxy and Satellite no proxy from different ISPs.
please help me with step by step procedures.
Thanks.
Here is ISP redundancy config http://technet.microsoft.com/en-us/library/dd897038.aspx
If you do load balancing than you need to use proxy.
Hello,
i have a headoffice with branches accross the country,from the headoffice,users can browse the internet through ftmg proxy,but my branches cannot browse the internet ,they go thru the tmg proxy too.prior to do this,they can.what am i not doing well or what has gone wrong???
You need to explain how HO & Branch is configured using TMG. Is it site to site VPN config? You must allow http & https from all the branches to go to internal. all site ip must be added into HO TMG internal network.
Thanks Raihan,

Hi sir,
I need a help from u… i have 2 domains in different vlan’s.. and the TMG 2010 is in workgroup. how can i control the users .. now everybody has access to internet. Same time i’m not able to upload or download from the ftp sites. i did ftp allow and removed the check mark from read only.. but still i can’t.. pls help.. waiting to hear from u
thanks
Does TMG server part of domain?
Do you have cross forest trust or just single forest config?
Make TMG server as domain member.
Add connection verifier
Add policy to allow or block internet.
TMG is not on domain its in workgroup in separate vlan
The two domains are single forest config..
How to add this connection verifier?
Hi,
I am facing problem with gotomeeting client communication via TGM2010 firewall. and Have noticed that its actaully dropping packet with the following error

hello sir,
i deploy the forefront tmg 2010. ip have two nic.
internet(wan) and lan. at lan nic ip 192.168.98.1/24and 99.1/24.i want to access any website from 192.168.98.50 without proxy.how to configure witout proxy web access rule in forefront tmg2010. i am able to ping from 192.168.98.50 to isp gateway server but not access the internet.
If you are behind proxy, without proxy you will not be able to use internet. This is the default nature of proxy.
I have installed TMG 2010. Wpad entry is there in DNS and DHCP Server. i don’t add my client in Domain. whenever they go to browser they get username and password screen and then browse internet. the problem is that the skype, yahoo messenger , gtalk & msn doesn’t work. please tell me how to do that or give me link that show each step how to do that.
proper WPAD config http://microsoftguru.com.au/2010/10/16/how-to-configure-forefront-tmg-2010-as-wpad-server-auto-proxy-discoverystep-by-step/
if you define “All Users or Authenticated Users or Users Group” can access internet in TMG than TMG will block rest of the connection. You have to add client in domain or configure TMG as workgroup. http://microsoftguru.com.au/2011/03/27/configure-non-domain-forefront-tmg-to-allow-traffic-from-domain-members-and-domain-clients/ opposite direction is true as well.
Raihan,
First of all thank you very much for your reply.
i have 2 servers
1 AD,DNS,DHCP = 192.168.0.2 Domain (ntec.local)
2 TMG = 192.168.0.1
My DHCP Range 192.168.0.1 to 192.168.2.255 Subnet 255.255.252.0.
I have followed your 2 web URL and configure WPAD on DHCP and also configure authenticate Server on TMG.
Problem.
1. Wpad is working as i am getting username and password screen on IE but not on Chrome, Mozila or Safari
2. when i put my username i.e NTEC\mac and password it doesn’t authenticate and i am getting following message from TMG
“407 Proxy Authentication Required. Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. (12209″
Please help me out as your help really matters to me.
Thank you very very very Much.
Basically i want my my client to use internet without adding them in domain and with authentication

Good Day,
I have a checkpoint firewall with an Exchange 2010 Edge server with Forefront for Exchange running on it. I only want to use TMG as a proxy server only not as a firewall is that possible?
Regards,
Hello Terrence,
you can put CheckPoint on FrontEnd and TMG as Backend server. you can make a DMZ like that way. You can configure TMG as proxy and reverse proxy for Exchange CAS. Short answer possible.
Beauty of TMG is, TMG can be used a firewall, proxy, reverse proxy, proxy cache, content filter, URL filter, publishing websites, exchange, sharepoint so many so on. Its up to you how you want to utilize.

Raihan
Hi Raihman ,
How r u?..
I am facing problem on my TMG server , i am not able to push patch through my patch manager on tmg srver ,same problem through antivirus server not able to push singnature on tmg server.
in short my tmg server not updated patch & antivirus through my server.
Sir can you help on this issue.
Hello Baibhava,
Please configure a firewall policy to allow communication between antivirus server and TMG. How do you patching TMG server, you should use WSUS for patching TMG or use direct windows update to patch TMG. This should fix the issue.
Note that TMG block all communication by default. you need to open port one by one. Regards, Raihan
Hi Raiman,
How r u?
I configured firewall rule but still facing same problem.Could u explain me how to create communication rule between antivirus server and TMG.
For patching i am using CA ITCM and facing same problem .
I already allow outbond port 42504 to 42511 for antivirus but still same issue.
Sir pls can u help me on the same isssue.
Thank
Vaibhava
Hello,
I have installed and configured TMG 2010 using a single network card setup. After following the steps above am still not able to access internet. What might be the problem? Have checked everything and seems correct.
Step1: check whether IE configured for proxy ?
Step2: are you able to browse without TMG, this is confirm that the problem with somethingelse not TMG.
Step3:configure right port for browsing
Step4:Create Web access policy for users who wants to browse through proxy.
Hi,
You have crafted some very nice articles on TMG setup, but I’m struggling to determine the best setup for my network. Currently I have:
Internet
|
Checkpoint – NAT
|
DMZ (two subnets designated as internal DMZ and external DMZ
|
Checkpoint
|
LAN
I would like to utilise TMG for the following purposes:
proxy for DMZ machines
reverse proxy for some macines in DMZ and LAN with NIS
future email hygeine
future OWA
What’s the best way to setup TMG, maybe Edge or Back-End?
I’m thinking 2 NICs and Edge setup with external NIC on DMZ external subnet and Internal NIC on internal DMZ subnet? Then internal routes would all go through DMZ internal gateway?
OR, is there a better/easier way that I have overlooked?
Regards,
James.
Oh by the way LAN has lots of subnets in case that makes s difference……….
Why you making things very complicated? Keep it simple and sweet (KISS) so that policies do not over lap and topology does not contradict with each other. If I was in your situation, I would configure back to back firewall for everything and get rid of check point. TMG is very powerful firewall, proxy, revervse proxy, content filter, publishing tools. TMG 2010 Enterprise provide NLB, ISP redundancy and central management features.
However you design is ok. But at some point it will be a complete mess. So adopt KISS polocy.
Thanks Raihan
Unfortunately although it would be simpler removing checkpoint is out of my hands. With that in mind and with my suggested design how would you setup the NICs?
I think DMZ ext NIC would have public dns server and DMZ ext gateway address and DMZ int NIC would have no gateway and no DNS but routes for all LAN subnets?
Regards and thanks
James
Mr. Raihan Al-Beruni
please I study ur scenario too much time for Forefront Threat Management Gateway 2010 (TMG)
we take this steps for this link http://araihan.wordpress.com/2010/03/08/forefront-tmg-2010-how-to-install-and-configure-forefront-tmg-2010-step-by-step/
but I received this message
• Error Code: 502 Proxy Error. Forefront TMG denied the specified Uniform Resource Locator (URL). (12202)
• IP Address: 192.168.140.3
• Date: 8/2/2011 6:37:59 PM [GMT]
• Server: SHRITTMG001.mjec.com

Look Mr. Raihan I will tell u about my scenario
I have Server 2008 R2 with Internet modem D-Link
I have 2 NIC in Server 2008
One (Internal) that what connected by Internet modem D-Link
IP: 192.168.0.2 and Default Gateway 192.168.0.1
Second (External) that what connected by my local Domain
IP: 192.168.140.3 and Default Gateway 192.168.140.1
When I take ur steps I fund error message 502 Proxy Error
Can u tell me please How I can resolve this problem or maybe I must do more steps
I have 100 user need to use internet by proxy
Please help me
External NIC should connect to modem and internal NIC should connect to internal switch or local domain. You should configure your TMG as Edge Topology. Please fix it and let me know
Thank You too Much
U understand my miss take by very fast time
and because I read many configure of many web sites
Thank you
Hello,
Thank you so much for the helpful article can you please help me out with some questions:
i installed TMG on hyper-v virtual machine, i’m using windows 2008 r2 as an OS and i have one NIC that is connected to a router and the router to the modem i don’t have an installed DHCP
here is where i find problems when i try to add a private IP range when installing i can’t add the range i want, when i select the adapter i have installed it takes some default values and continue with the installation correctly.
also when i configure a firewall rule to filter and deny some URL’s user are able to browse the restricted websites
can you please tell me what i’m doing wrong as i’m using TMG for the first time and i don’t have any experience in ISA.
what sort of error you see when you try to add private ip range? Why you are using single nic?
it’s not an error but when i add it i don’t find it on the list, also i have one NIC on the physical machine that’s hosting the virtual i’m working on.

Hi,
How is having a hyper threading enabled gonna impact my TMG server?
Thanks!
TMG need a dual core CPU that is 1CPUx2 core or 2CPU. Hyper threading may impact on underlying operating systems but not directly on TMG.
Please explain your question little bit more.
I’m planning to setup my own TMG Server that has a dual-wan(internet) capability… As per my understanding not all processors have that hyper threading capability… What can happen if my processor doesn’t have one? How can it impact the performance of my TMG? Please enlighten me, thank you very much sir!
TMG Hardware requirement http://technet.microsoft.com/en-us/library/ff382651.aspx
If you follow these rules it will impact on performance otherwise it will impact on performance.
Dear Mr. Raihan Al-Beruni.
First of all, thank you for your Blog. As a newbie, I find it quite helpful.
Here is my question though. I have F TMG 2010 installed as an Edge Firewall, acting as Proxy Server which blocks the Internal Network’s HTTP and HTTPS except for a few chosen websites.
Now I am unable to send or receive e-mail (provided by a 3rd party ISP with Outgoing Server: smtp.dsl.telkomsa.net) via this new Proxy.
Please show me in the right direction.
Thank you
Hello Hannes, Where is your mail server? is it in cloud or internal network? Is it Exchange? How do you check email via outlook client or webmail. for webmail, if you allow https than it should work. for SMTP, you need to create policy for that. Please answer my questions I will be able to help you.
Thanks for your help Raihan, please excuse my late reply.
Our e-mail is provided by an external company, with their own mail servers. We download e-mail via pop3, and send via SMTP. Now, I tried creating a policy/rule: Allow POP3 & SMTP from Internal to External Network for All Users. But still MS Outlook responds that it can’t find the server (pop3.telkomsa.net).
To be honest, I don’t have an idea about MS Exchange.
Although I would like my server to download all mail for all users, and then forward it to each user’s PC. I assume this is when Exchange comes in. But for now, if I can receive mail via my Proxy/MGT server, it’ll be Great!
Thnx again for your help.
Hannes

Hello!
When a user sends a request from IE to Internet, TMG opens only part of the site. TMG authorizes the user as “DOMAIN \ username” and writes in the log “OK.” Another part of the site is blocked and TMG wrote in the log “Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied” and writes the user name as Anonymous. When a user sends a request immediately from Mozilla, the site opens normally. Why?
Best regards, Dimon
On the Monitoring>connectivity verifier>Add AD connection. Please configure Proxy and port for IE through GPO. Did you configure proxy in mozilla?
TMG will block inappropraite websites and contect by default unless you create a policy for user.
I created a rule that allows the user to visit Web sites. TMG in the log says that it was applied this rule. I set both browsers to visit the site through a proxy server. Through the Mozilla site open completely, but the Internet Explorer site opens partially. The same site with the same computer with the same user in the same time.

Hi Raihan,
I use my FF as an edge firewall, Now I need to forward some ports from external to a server in the internal network. How can I accomplish this? For my Sharepoint and Exchange I used the web publishing and Exchange wizard. But I also need to forward ssh and VPN with EAP + certificate authentication.
From External to internal is called reverse proxy. You can publish any website or secure website using TMG. Just select source as external/internet and destination as the server you want to point. Similarly point SSH and VPN server. Import certificate into TMG server.

L2TP IPSec VPN http://microsoftguru.com.au/2009/10/08/how-to-configure-l2tp-ipsec-vpn-using-isa-server/ though this steps are based on ISA but TMG and ISA are pretty same.
Let me know how you go.
Dear Raihan ,
i have a problem … i had a rule for every department to access a certain websites . one url set of this was for gmail and it was working fine , suddenly 2day its not working for this users and its only working for the users who has unlimited access . can you help me with this issue .
Can you please monitor traffic for that user using TMG and see what error you get and update me please. Did you change any rules that conflict with existing rules.
Hello, I’m planning to migrate from ISA 2006 to TMG 2010.
At now, I have a 3 leg configuration with Internal, External and a DMZ used for guests connecting at my office to the internet.
I’d like to virtulize TMG but the server can host 2 Nics tops (it’s a blade server) so I was wondering if there’s a workaround to keep 3 subnets with 2 nics.
The other way is to keep existing ISA 2006 and side it to TMG, could it work?
If your blade server thats is ESX/Hyperv host connect direct to trunk port than you can configure port groups for all three vlans/subnets and add three nics for TMG server. thats easy as this. for hyperv you can configure vlan id for three subnets.
Blade chassis directly connect to trunk port. you dont need to worry about that.
Hello Raihan,
I have a little question for you, its that the policies in TMG do not apply to secure NAT clients, I mean when I create new policy it applies to web proxy clients but not to secure NAT clients.
I don’t want to change DHCP options (remove 003 router), is there anything that can be done in TMG server?
Many thanks
what type of topology you are using? I am not clear about your questions.
Thanks Raihan for your reply,
the topology i am using is edge firewall.
Concerning the DHCP options, client are getting Default Gateway along with the IP address, I dont want to remove it.
Hello Raihan,
i have a problem with yahoo mail i cant download pdf attachment files, i use tmg in my network, and i think there something in tmg Prevents me to download these files.
What sort of policy you have configured? Did you configure pay load? you find that in right click your firewall policy>configure HTTP options
Raihan
I am getting problem to access gmail and hotmail account on forfront TMG server. I didn’t make any rule to stop any website i just made rule for access all sites.
Please reply…
Thanks
TMG does not block yahoo and hotmail unless you publish a firewall policy to block gmail and hotmail. Can you please all the firewall and web access policy?
Hai Brother…
I have problem… I installed FF at Branch Office with two NICs , one for LAN and the other for WAN. I am running 2 roles, DHCP and DNS in FF server.
Oh almost forget.. The FF run on Windows 2008 SBS SP1. I connected FF to Central Office through VPN site to site. And joined to domain at Central Office. I have 6 client computers that using windows 7 pro 64 bit and joined all to domain. Everything running okay…. but suddenly all client computers could not be connected to domain controller. I saw to Network Sharing Center on Client Computer and FF server .. LAN unidentified and circle mark is still running. No IP address in All Client Computers.
By the way I still remote FF from my Central Office….
Can you please run tracert command to domain and check where is client blocking to? Is your client gettting IPs from local DHCP? You config seems weird to me. Why you configured DNS and DHCP in TMG server?
If you seems this is weird configuration..so do I. I am just continuing to maintain the work that have done by the man before me…. (I don’t know who did give him inspiration to make configuration like this)
This the error message that I captured from DHCP role ” The DHCP service failed to see a directory server for authorization”.
This the result of nslookup command :
default server : unknow
address : 10.10.66.1
for standard of comparison, I show you the result of nslookup command that i run in FF server (with the same configution) from another branch office that connected to central office via VPN site to site :
This the result of nslookup command in GW-PDG server
default server : dc2.wk.local
address : 10.10.1.13
(it have to be like this)
All clients are getting IPs from local DHCP.
Hi
We are currently running a server with ISA 2000…. I want to upgrage to TMG 2010. Do I have to start from scratch for all of the incoming/outgoing rules?
Thanks
update all SP. then try export and import config. but i dont think this is going to work. you might need to redo the whole thing. http://support.microsoft.com/kb/982901
HI Raihan,

Hi Raihan,
Would this scanerio work?
Internet –> Cisco ASA / NAT services (NIC 192.168.0.1) –> TMG (external NIC 192.168.0.2) –> TMG (Internal NIC 192.168.10.1) –> Internatl web servers (192.168.10.X)
Basically I would have all the external internet traffic coming to my Cisco ASA where I have some external valid IPs, the Cisco would translate/Nat to TMG external card that would then pass to the internal NIC / internal web servers.
Thanks,
Luciano
configure ASA as Front End Firewall and Configure TMG 2010 as backend firewall and proxy. yes it will work.
Hi Raihan,
Two internet links, two TMG Servers in the same AD Domain, how to create a load balance between the servers ?
I can create a load balance if the servers works in a Workgroup mode, but i cant find a solution to AD domain. I wouldn’t like to use a EEM server.
Tks

Hello,
I just installed TMG 2010 and configured it to allow web access.
But when i installed TMG client on workstation, it is not able to connect TMG Server.
Is there any specific policy need to be created to allow access to TMG server.
Note. – currently internet is accessible.
you dont need to install TMG client. you can but you dont. configure IE for proxy and browse internet thats all.
Hi Raihan,

can you halp me ?
Add AD connectivity verifier in TMG>Monitoring
Create AD Group.
Add that AD Group into TMG
Add that group into firewall rules
If you want to add or remove from any groups do it though AD not via TMG. that should work.

Hi,
Great guide, some really useful info in there. I’m currently in the process of setting up a new TMG server on our network and I have a question that I can’t seem to see the answer to. At the moment our LAN connects directly to a hardware firewall which in turn connects to a router for our ADSL connection. The TMG will sit between the firewall and the LAN so it will use two NICs, one internal and one external. The only thing I can’t see is how TMG knows that the external NIC is the one used to send traffic to that’s not local. I hope that makes sense and any clarification would be great.
Many thanks,
Ben.

Hi Raihan,
Need your advise on solutioning a TMG requirement.
We have a old ISA 2000 server which connects to both Internal offices as well as other client offices.For these client offices, this ISA server acts as a firewall to access resources with in the internal network.
Now we are planning to deploy TMG enterprise server on virtual environment and now we have no idea how was the existing ISA 2000 configured.
Could you please advise me which possible way we need to configure to support the requirement. The Virtual server has 2 Vnic’s and we are not sure in which network topology mode we need to install.
I am also from Australia. If you can provide your Contact number, I can explain more on detail about the requiremnet and the environment.
Sri.
Dear Raihan,
This is from the bottom of my heart that you are doing a G8 Job my Friend…. I liked a lot…. Keep it UP……..
Hello Raihan,
I need 2 Help from you the first one is that I want to block Team viewer through ISA 2006 SP1 and Second is we have installed ISA 2006 with Edge Firewall Network Topology and we are using a Single NIC for this, kindly let me know is this the proper configuration. I have gone through your article and found that there is one more Network Topology which suits my environment is Single Network Adapter Topology, as we have assigned only one NIC to our ISA Server we can go ahead and use this Topology. We are running this server on Hyper-V and now we are planning to upgrade our ISA Server to TMG, so we can go ahead and configure Single Network Adapter Topology.
Well few more things we have 4 NIC on the Physical server and we have done Teaming 2*2 and assigned one NIC to the Virtual one.
Hi Raihan,
Please help me also, as i have TMG 2010 installed & need to configure one rule in which i want to give access to only selected websites rest all internet will be blocked. Please suggest how i can do it.
Thanks,
Anu
muy buen aporte! muy certero, pero tengo un par de preguntas, esto sustituye al isa server logicamente, pero en mi caso tengo checkpoint firewall-1 tamien, tambien sustituiria a este?, cuales son las desventajas de forefront TMG? lei que microsoft dejaria de sacar actualizaciones ya quiere irse deshaciendo de el poco a poco, es esto cierto?
Forgive the previous comment, very good contribution! Very certain, but I have a couple of questions, Forefront substitutes the IsaServer logically, but in my case I have checkpoint firewall-1. Does ForeFront do Checkpoint’s work also?, which are the disadvantages of forefront TMG? i read that Microsoft stoped of extracting updates already wants to be falling apart of little by little, is it certain this?
Hello Raihan, Congrats. You have an excelent Blog and I surprised with your high experience with this solution. I would like to know what is your recommendation about my case.
I have a cisco firewall to protect my network and OpenDNS to web filtering and malware protection but this service will not free anymore this year.
For that reason. I am looking for a cheap and good solution as TMG but I don’t have clear what is the best fit network topology scenario. My network is 90% Microsoft and I have availability a physical server with minimum requirements and 1 license promo TMG standard.
What do you think about this?.
Thanks and Regards,
Hi Raihan, It´s great blog. Congrats. I would like to know if you can help to me. Currenctly. We have OpenDNS for web filtering and I think that ISA Server or TMG could be a better solution for many reasons but I have a little confuse what is the best fit network model that we should be to implement. I have a Cisco Firewall to block and I think that one server with TMG for web filtering for user internal users. What is your best recommendation?.
Thanks and Regards,

For these i have installed AD (win 2008) , TMG1(win 2008) & TMG2 (Win 2008) in VM and added to TMG to domain.
And now in TMG1 & TMG2 in which mode i need to install and how to configure load balancing mode for my TMG server.
Pls Suggest.

Hullo Admin, my question is: currently i have a network where the setup is ISP connected to the modem from the modem to the router and from the router to my server and LAN, now this is the question, i would like to add TMG firewall on the network. what set up is the best to use? and could still the config. be the same as this in the post deffinately changing the IPs?
thanks.
I am not clear about your questions. You should use edge topology as per your description. ISP…>Router…>TMG Edge Config…..>LAN
Can it be installed on a Domain controller?
No. Never.
Hi, so..What is the way around it? Because I need both the DC and TMG for management….Does it mean I will have to install on 2 different machines? …or can I create a VM on the DC and install TMG ..help!!
