o Edge rewall—In this topology, Forefront TMG is located at the network edge, where it serves as the organization’s edge rewall, and is connected to two networks: the internal network and the external network (usually the Internet).

(h p://araihan. les.wordpress.com /2010/04/layoutlargeedge.png) o 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.

o Back rewall—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.

/2010/04/layoutlargeback.png) (h p://araihan. les.wordpress.com/2010/04/layoutlargefront.png) o 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 con guration when Forefront TMG is located in the internal corporate network or in a perimeter network, and another rewall 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: o Forward (CERN) proxy for HTTP, HTTPS, and CERN proxy FTP ( only). o Web caching for HTTP and CERN proxy FTP. o Web publishing. HTTP-based communications, such as Microsoft O ce SharePoint Server, Exchange Outlook Web Access 2007, ActiveSync®, and remote procedure call (RPC) over HTTP (Outlook Anywhere, Terminal Services Gateway or WSMAN-based tra c). o 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:

Raihan says: June 8, 2010 at 8:54 AM Hello Mohsin, You need TMG enterprize version. Once you con gured primary TMG server. Then install second one, at the begining of installation it will ask you to with another TMG Array or con guration and storage…. Once the array, it will get all the con g. Both TMG servers must ADDS. Otherwise you will not be able to install certi cates and con gure integrated authentication for internal network.

Sami says: August 22, 2010 at 8:34 PM i just want to ask about something ,, how did u do your con guration 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 Reply Raihan says: August 23, 2010 at 12:18 PM 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 h p://microsoftguru.com.au/2010/06/17/how-to-con gure-back-to-back- rewallwith-perimeter-dmz-topology-step-by-step-guide/ If you can send me your network layout then I can advise with speci c 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.

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. 08/12/2013 11:22

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 tra c from the virtual machines etc too, so i guess they need to go through the TMG as well. Suggestions? Reply Raihan says: August 26, 2010 at 10:32 AM 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 di erent sites follow my new blog h p://microsoftguru.com.au /2010/08/24/how-to-con gure-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. h p://microsoftguru.com.au/2010/06/17/how-to-con gure-back-to-back- rewallwith-perimeter-dmz-topology-step-by-step-guide/ If my guess is wrong then clarify those I mention earlier then I will provide perfect answer. Reply Peter says: August 26, 2010 at 5:41 PM Hi, Thanks for your . 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 08/12/2013 11:22

accessible from the internet too. How would we set this up using TMG? Or should we do a di erent setup alltogether? Thank you. Peter Raihan says: August 27, 2010 at 9:05 AM In your scenario, few things going on. 1.TMG Con g 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. h p://microsoftguru.com.au/2010/06/17/howto-con gure-back-to-back- rewall-with-perimeter-dmz-topology-step-by-step-guide/ You may use 3-leg perimeter also.

Allow RDP port in Router and TMG. .microsoft.com/…/WS08TSGatewayServerStep-By-StepSetupGuide_En.doc Peter says: August 27, 2010 at 3:35 PM Hi again, I’m a li le 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? Peter says: August 27, 2010 at 4:12 PM 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. Raihan says: August 31, 2010 at 8:53 AM 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 [email protected] for further help. Email me your visio diagram. Lets start from there. Let me know your location. I am on WST, Australia. regards, Raihan

I installed Forefront on a testing environnement I chose the back Firewall option which suits our architecture. However, I would like to lter speci c 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 lter some websites? Thank you in avance for your help. Amrai 08/12/2013 11:22

October 21, 2010 at 7:53 PM 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 o ce for internet access. Been working ne 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: rewall 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 x this problem. Been working on to x it for three week with no results.PLEASE HELP.SOS Reply Raihan Al-Beruni says: October 22, 2010 at 8:29 AM 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 rst 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 ’s pro le,…so rst do a cleanup with AV or ASpy tools,…then you have to backup the MyDocs, les on Desktop, Favorites, ect,…then delete the pro le,…create a clean one,…copy the saved les back into it. Repeat for every that has a pro le ont he machine. Clean install windows. Update service pack, run malware removal tools. add signature blocking rule and block con cker,blaster, worm, spyware etc..

Reply Nabil says: January 25, 2011 at 1:00 AM 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 o ce wish access the LAN trough and leased line directly connected to the LAN switch . here’s a simpli ed diagram : (Remote o ce : 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 , 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 de ned as pretected network with the good routing rule in the TMG console . i tried the one ” h p://blogs.technet.com/b/sbs/archive/2007/11/29/network-behinda-network.aspx” but it dose not solved the problem . i m looking for anything to do . any ideas are welcom . thanks in advance . Reply Raihan Al-Beruni says: January 26, 2011 at 2:02 PM I am ready to help but you need to help me explain your con g. If the diagram shows in the url is same in o ce. Then you should do things a bit di erently. What type of topology you are using in TMG? Eg, Edge, Back rewall, 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: Con gure Edge Firewall in TMG & Add both IPs in the internet network of TMG Step5: Allow Policy for Routing, Ping, DNS, DH between both IP ranges in TMG Step5: Allow H p & H ps You are good to go. If you have two sites and TMG con gured 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. 08/12/2013 11:22

By default TMG block everything unless you de ne it. Reply Georgi says: February 21, 2011 at 12:32 AM 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 li le 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 con guration I had setup 3-leg topology and there I listed the rst 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 nd any di erence but the route keeps adding itself.Tried to deleted it but without success. I couldn’t nd some dependency which couse it to “auto add” itself…

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 be er/easier way that I have overlooked? Regards, James. Reply VFRJAS says: July 29, 2011 at 8:52 PM Oh by the way LAN has lots of subnets in case that makes s di erence………. Reply Raihan Al-Beruni says: July 30, 2011 at 9:08 PM 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 con gure back to back rewall for everything and get rid of check point. TMG is very powerful rewall, proxy, revervse proxy, content lter, 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. Reply Vfrjas says: July 30, 2011 at 9:59 PM 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?

Hannes Jansen says: August 12, 2011 at 1:38 AM Dear Mr. Raihan Al-Beruni. First of all, thank you for your Blog. As a newbie, I nd 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 Reply Raihan Al-Beruni says: August 12, 2011 at 1:31 PM 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 h ps than it should work. for SMTP, you need to create policy for that. Please answer my questions I will be able to help you. Reply Hannes Jansen says: August 18, 2011 at 9:36 PM 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 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 s. But still MS Outlook responds that it can’t nd the server (pop3.telkomsa.net). To be honest, I don’t have an idea about MS Exchange. Although I would like my server to all mail for all s, and then forward it to each ’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.

September 12, 2011 at 4:05 PM Hello, I’m planning to migrate from ISA 2006 to TMG 2010. At now, I have a 3 leg con guration with Internal, External and a DMZ used for guests connecting at my o ce 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? Reply Raihan Al-Beruni says: September 21, 2011 at 4:17 PM If your blade server thats is ESX/Hyperv host connect direct to trunk port than you can con gure port groups for all three vlans/subnets and add three nics for TMG server. thats easy as this. for hyperv you can con gure vlan id for three subnets. Blade chassis directly connect to trunk port. you dont need to worry about that. Reply Tolik says: September 13, 2011 at 8:35 PM Hello Raihan, I have a li le 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 DH options (remove 003 router), is there anything that can be done in TMG server?

I’m currently in the process of se ing 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 rewall which in turn connects to a router for our ADSL connection. The TMG will sit between the rewall 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 tra c to that’s not local. I hope that makes sense and any clari cation would be great. Many thanks, Ben.

We have a old ISA 2000 server which connects to both Internal o ces as well as other client ces.For these client o ces, this ISA server acts as a rewall 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 con gured. Could you please advise me which possible way we need to con gure to 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 number, I can explain more on detail 08/12/2013 11:22

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 con gure Single Network Adapter Topology.

June 9, 2013 at 7:37 PM Many thanks It’s really great work. Please how can I con gure secure NAT clients on TMG 2010 ?TMG rules works ne when i de ned TMG address as a proxy server in Internet explorer LAN se ings and port 8080 as well.but i prefer to use secure NAT clients instead of web proxy clients . Our network is complex network with routers bridging subnets between the client and Forefront TMG. Thanks in advance Reply Raihan Al-Beruni says: June 11, 2013 at 2:19 PM to con gure NAT between internal and external or vise-versa, just create network rule in Networking>Internal Network or external network>Create new rule. create your desired rule. Reply Mark says: July 24, 2013 at 9:04 AM Odd question, probably: 1) have a two-stage H/A rewall composed of a pair of Juniper SRX and a pair of TMG2010 servers. The SRX are on the Internet side, the TMGs internal from them. 2) I need to route an internal server through the TMG array and have the internal ip address presented to the Junipers so that it can be used as input for a VPN rule. (Partner is requiring a Public address within the tunnel, not just on the outside, so I have to do the NAT at the Juniper side) 3) Distant end of the VPN is a Cisco ASA. 4) Created the tunnel and set up rules to nat tra c, but I ran into an issue when trying to route via the TMG array — the array insists on NAT’ing to its ‘external’ VIP vice ing the address on to the Juniper. 5) A empted to get around this by sending to one member of the array and not the internal VIP, but I think this might be causing issues for the return tra c, which is sometimes being closed for non-receipt of a SYN/ACK (subsequent non-SYS packets from the client are then dropped for no existing connection) Any ideas? Reply Raihan Al-Beruni says: July 29, 2013 at 12:43 PM First you have to create back to back rewall between Juniper and TMG. Add internal IP address range into juniper internal IP address range. this ip range must be added into the rules of juniper. Then same internal IP address range must be added into internal network of TMG. then publish the VPN connection within TMG and Juniper to Cisco ASA. then publish rule allowing ip range in ASA and Juniper. this is called two tier rewall. Its a great rewall from security point of view but sometimes di cult to maintain.
