I'm trying to set up a campaign server. I have DMZ turned on on my router and I am forwarding ports 7777 and 27900 to my computer's IP address. I even had a few random people connect to it. But my friend cannot get a connection to my game. She can see it in the server list and can connect to other people's servers though. I tried turning DMZ and port forwarding on on her router too with no luck. We even tried hosting the game on her computer and I couldn't get a connection to her either. Anyone know how to fix this problem? Thanks!
