Same thing here. I used to play games every week end with my GF, but now we just can't connect to eachother's game.

Sending udp packet from 6112 to 6112
Received from /66.134.89.225:6112 to 6112 "udp pass"
udp port 6500 Receive timed out
udp port 27900 Receive timed out
udp port 27901 Receive timed out
udp port 29910 Receive timed out


That's my result with the net test. Somehow, my GF can't run the test on her computer, and since we're far away, I can't really see what's going wrong.
I don't know what my router is. How do I check that? And why would it stop working suddenly? We've been playing DoW for months, and then, boom.
