Let's say, I have a server that is directly connected to the internet (no firewall), and sits on 126.96.36.199 externally, and internally sits on 192.168.0.1. I have my domain's records set up so that mydomain.com points to my external IP.
I also have another server, which sits on 192.168.0.2, but is only accessible internally, as I only have 1 external IP address. I have forwarded server2.mydomain.com to my external IP, but of course, it points to my first server.
Is there a way, to possibly route the traffic coming from server2.mydomain.com to the other server? I have been reading about this, but it's not very clear, using Microsoft ISA Server.
