How to Config Shorewall to make this work?
I have set up a debian router and firewall using shorewall. I have two NIC. eth0 is connected to the Internet, eth1 is connected to a switch. The switch is connected to two PCs.
My problem is, when PC1 host a game in warcraft 3, PC2 cannot join the game if it is through Battle.net or cannot see the game if it is through LAN. But players from other network can join my game.
I don't know what should I do to shorewall to make PC2 and PC1 communicate. Could someone give some advice?
