For web access, the XP clients will not need DNS or DG settings as you will define a proxy server setting in the web browsers. They will therefore just an IP address from the 172.16.1.x range.

If you want to access non-web services, you will need to configure the clients with DNS:4.2.2.2 and DG:172.16.1.2.

Hi!

Excellent guide! Thx a lot.
But one question:

I know ISA/TMG was not ment to be used with DHCP enabled on either NIC. However I think many peopla like me still use DHCP on the External NIC.
How should I configure DNS in such a case?
I use Internal DNS on both External NIC and Intelnal NIC. Otherwise I get a DNS from my ISP...

2010-07-07T13:55:23.648+01:00

Hi Yaseen,

ISA only supports a single external interface so you need to either use the ethernet NIC or the ADSL model, but not both.

For your other questions, post a question on forums.isaserver.org and I can answer better there...

Hello,
Thank for information.

I have questions:
Suppose that you have ISA with 2 NIC, and one ADSL modem as following:

ISA Network Configuration
-Internal Network:
IP: 10.0.0.1
DNS: 192.168.1.1 (of local)

-External Network:
IP: 192.168.1.2
GW: 172.16.2.3

-ADSL Modem for browsing Internet:
IP: 192.168.1.3

2010-06-29T16:03:27.423+01:00

Hi Allan,

Configure TMG with a single DNS server pointing at your internal DNS server.

If you need to, you should then be able to configure this DNS server to do conditional forwarding to internal or external DNS servers as required.

Only ever define DNS on the ISA/TMG internal interface; doing otherwise will cause problems...period!

Thanks for the article. One issue I have is my internal DNS forwards to another networks DNS (we are internally connected but no trust exists). For this reason if I leave my external DNS blank it will never work correctly so in ISA 2004 I have internal DNS on the internal card and my ISP's DNS on the external card. It works fine with ISA 2004 but I'm having issues with TMG 2010. Any

You can use this guide or my newer version which covers TMG/UAG with Windows Server 2008:

The two ISP NICs will be configured the same using the settings described for the "External Interface" in my guides.

Thank you.

I'm looking for help on 3 NIC Scenario, where I'm using the ISA server as Web Proxy Server. I want to use 2 NIC cards to link to ISPs and one NIC to link to Clients in my network.
So, I want to implement Load Balancing for the two NICs so that the clients on the 3rd NIC can avail services from both ISPs and can also benefit from web proxy server.
