How can ISA be used to do port forwarding?

I am experimenting with setting up a small security test office and want to use ISA Server as described in MS KB 321516 (How to use the Windows 2000 Routing and Remote Access Service or ISA Server with a DSL router for Internet Access).

I have a LinkSYS BEFW11S4 v.2 Cable/DSL Router that I have successfully configured to allow port forwarding for things such as www, ftp, smtp etc. The LinkSYS Router is limited though since it only forwards to addresses on the same subnet.

I would like to setup the ISA Server to act as the firewall/proxy in between the Internet and my test network. My question is how would I accomplish port forwarding with the way it is proposed in the above article. If my Firewall side of the equation is a network and the other side is setup as, say,, how do I configure ISA Server to forward requests from the LinkSYS Router to the network.

The router would have to forward all requests for port 80, 25 etc to the ISA Server interface, say, but how does ISA translate that to the network?
