I don't know if you can use state rules to allow more than one machine to play the games from behind your NAT/firewall box, but I've found that if the game uses UDP for communications (and most internet games do), and you only have one IP address visible to the internet, then you need to pick a single machine for running the game, and then set up the IP rules to route the UDP packets to that port to the machine that runs the game. For example, I play Starcraft, and all the Blizzard games use UDP port 6112. In my natd.conf, I have: redirect_port udp 10.0.2.22:6112 6112 where 10.0.2.22 is the IP address for the internal machine on which I play Starcraft. My firewall has the following after the divert rule: add 5005 pass udp from any 6112 to any 6112 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
