I'm using pfSense 1.2.3RC1 as my home FW. I'm trying to host coop games in Cod WaW. Players can join my lobby and chat, but when I start the match the game basically time out after loading the map.
I originally just forwarded and allowed ports 28960 and 3074 both TCP and UDP to the PC I'm using to play. I then noticed in the FW log that packets originating from other players with destination ports above 1024 were blocked. So I forwarded and allowed all TCP and UDP ports 1024:65535 to the PC just to be sure and still I can't host games.
I followed the suggestion on this forums and enabled advanced NAT with static port and it still didn't help. For the record, Windows FW is off on the PC I use with the game.
