Yes, I meant NAT :)
Changing http port 8080 and etc all depend on the box setup, e.g. how many
IP available. since ISA need port 80 for http traffic as well, if you have 2
or more IPs you can disable socket pooling, and make one listen for ISA and
others for IIS.

you just using RRAS, right ? and not running NAT from ISA.

I do not have a RRAS environment to test this :(
