I have a debian GNU running as a server. I use shorewall to make it work as a router.
Recently, when i host a game in battle.net using PC1, PC2 in the same network could not join the game but other players on the NET can join. If I host a game using LAN, PC2 and join PC1's game. I have tried to config /etc/shorewall/rules but didn't help. Can anyone give me some advice? THanks in advance.
