Hi Mo We use the following setup: GW server on the internal network IIS on the internal network IIS has a site setup to use GW webaccess and is published using ISA normal web publishing rules. Since IIS and GW are on the same local net, they can communicate without any prob. If you are going to be putting the web server in a DMZ or something like that, you will need to use server publishing on ISA to allow access from the web server to the GW server (TCP:7205 I think).
