(I hope I'm posting this in the right section...)

I'll try to keep it short. On this Games For Windows Live game (Dawn Of War II) I can connect to and play on the internet just fine. Enabled port 3074 and 88 so that GFWL wouldn't have any problems connecting to my computer. Port 3074 has an issue however.

With the PortForward testing program (Open Port Check - PortForward.com), whenever I check port 3074 outside the game, both UDP and TCP show green and are forwarded correctly. However when I'm in the game, alt-tab, and run the test again, it shows UDP red after testing, indicating it's not forwarded correctly.

I think I know precisely what the problem is; either something in GFWL or the game itself is blocking port 3074. But why it's doing this, and how to find out what it is, I really have no idea. Any help would be greatly appreciated, and let me know if I can provide anything that might help!
