have you updated the game lately?
try this go to your steam library, right click MW3 >properties>LOCAL FILES>VERIFY INTEGRITY OF GAME CACHE
Do this for both the single player and multi-player
which ports did you forward? they should be these
tcp: 3074, 27014-27050
udp: 3074, 27014-27050
If that doesn't work try DMZ:
And if you have a personal firewall. make sure it allows iw5sp.exe to pass both ways
Thx for your reply.. I've done what u said.. And I searched before for the ports, and I found this:
So I did that, but when I hit save he says something like ''port overlap occurred'' so I changed the UDP to 27016 .. The only good thing is, that I now get the error: ''The servers are not avaible at this time, please try again later or visit....''
Soo yeah, it still doesn't work..
And I've tried DMZ.
