I have a customer that is using Microsoft ISA Firewall. The problem is they have a server that uses port 443 and we have a server that uses port 443 (we can't change that port on our server). I was wondering is there a way to point a different wan port say 81 to our servers port 443 in the firewall. The customer says they can't. I have never seen a firewall that can't do port mapping. But there is always a first time. Thanks.
