EDIT2:LAN games does seam to work now, but we both cant connect to online games.
EDIT1: I tried a online game and I've got the same problem there as well......
This game ends up in the trashcan if I only can play singleplayer games with it. DotA at least works..
Ok nevermind, I got it to fucking work!!!!
@Monk, you should tell people who have had the same problem as I have with the double-NAT problems that they should put their second router as an accesspoint instead, that fixed it for me at least. Or at least in the PFPortChecker program. Haven't tested it ingame yet.
