I want to play against the other computer i have in the house. I even bought 2 games, conquest (+ptw), and civ3 gold. However even when i put DMZ on my router my computers get kicked off saying im behind a firewall. I'm pretty sure if i disconnect my cable modem and not connect to the internet it will work because it wants to connect to gamespy everytime. Can anyone else tell me if my theory will work? it would be nice if both computers could play against other people on the internet too but it almost sounds like they both need their own seprete internet IP's instead of sharing one through my linksys router...
