hi friend, sorry about your troubles. that's a tough one to fix unfortunately. I'm not sure if it's related to the upnp that's part of war2combat v4.01 or what but it happens sometimes & not really sure why. you can try manually setting your game data port to first 6112 and if that doesn't work changing it to 1024 and see if it helps. could also try enabling the "DMZ" setting in your router as an alternative to port forwarding and see if that helps.
