I have spent most of yesterday trying to find the answer to this online, and have yet to come up with anything. So I apoligize if this is a repeat question. I host COD4 dedicated as well as I have hosted AIWNet, but for FourDeltaOne, When I port forward my MW2 server's game port of 28996 clients cannot connect, yet it has no issues whatsoever if I DMZ the server (which I really don't wanna do) This tells me there may be additional ports required to be forwarded? If anyone has come across this problem any assistance would be greatly appreciated.

Why not just use ports in the 60's? i.e 28961? or 28969? And if so do those ports even work?

Well I figured out the problem, After isolating what was the only thing different about this server from the rest, it ended up being that I had forgotten I made this server a DC (for lab purposes). Disabling windows firewall wasn't enough. So a simple dcpromo and bam no issues. Thanks anyways! :-D

Thats good to hear.
