Hi, I am running ISA Server 2006 with two NICs : one for Internal and the other for External network (Internet). I have succesfully published OWA2003. Now our customer wants to publish MOSS Intranet, which located on another network. I need to add a third NIC to my ISA.

- Do I need to reinstall ISA and reconsider the current policy rules as well static routes and Network's IP address ranges, in order to the new NIC to be recognized by ISA ?

With regards, GWAV

There is no need to reinstall ISA from scratch.
1) Export the entire ISA configuration to a location.
 2)  take a separate backup of Firewall policy rules that exists in the current setup.
3) Introduce the third NIC on the machine and run the 3 leg perimeter network template if it matches your network requirement.
4) Once this is done, you can reimport the firewall policy backup XML file. By doing so, the existing rules for OWA/publishing shouldn't be affected if you've not changed the server locations or ipaddresses.  from there on, you can make use of the new network that you've added to ISA by defining the LAT for the same .
Note: please test this lab as i've not tested it yet.

Hi, Thank you for the suggested solution and comments. Our ISA2006 is now configured as an Edge Firewall.  It will change to  a 3-Leg Perimeter network. Will import succeed ad will old rules wok fine, since it a different network topology ?
