Need help blocking all ports except a few
I'm new to iptables/chains and need help setting up my new Debian system.
The system is going to be a gameserver and I've never set that up before.
The only services that really need to be open are ssh2 and the game server.
The game server needs these ports opened:
5120-5300 (UDP only)
6667, 80,27900,28900,29900.29901,13139 and 6500
Any takers? Or some pointers? Tried Firehol, but it complains that it needs a
kernel higher than 2.3
