Linux has had the iptables packet filter since kernel 2.4.x (ipchains in
earlier kernels). There are several gui front-ends to iptables, but I've

Not unless your linux machine is sitting in between your gaming machine
and the router. But depending on your router firewall, you may find
iptables to be more versatile.
