I have sharepoint 3.0 installed with ISA 2000. I have two NICs on the PC one is 192.168.1.3 (external side of ISA) and 192.168.0.20 (internal side of ISA). I have the Sharepoint setup to 192.168.0.20. I have also setting it to 192.168.1.3 with no luck. I have a basic Linksys router there with the port 80 forwarded to the 192.168.1.3 of the Sharepoint Server. I have a web publishing rule in ISA with link redirection setup. If I connect to the VPN i can get to the site but otherwise from outside the internal network I get a page cannot be displayed.
