Trying to troubleshoot coop in my map so I started another steam account and wanted to play between two PCs. I have two COD WaW's. I can't seem to connect to each other though. I have this problem if I don't forward my ports usually, but I can only forward the ports needed to one internal IP address. Anyone know what my issue is or how to get around it, or another way? I have a D-Link DSL 2750B

[SOLVED]
I found this link and have made i work so far. I will further test later this week. Basically says "Hosted online game with PC No.1, then went to the find game option with No.2 and set it to search for a lan game and the server was there, I clicked connect and it connected instantly"

This worked fine for me as long as I hosted with the PC that was wired to the router/motem and not the wireless one.
