Hi, Eek .. let me try that again. My earlier post has an old copy of the iptables script. I've timmed it down so it should all work with a simple default = ACCEPT iptables firewall. I have two scripts I use to do something similar to this. I figured this out just reading howto's on the web so it could be fully wrong and I may get flamed for posting them. What the scipts does is connect two networks and is an internet gateway for both. I think this setup should work OK for your gaming setup. Just edit the networks to suit what you need. The Linux router box has 2 NICs eth0: 192.168.1.0/24 eth1: 192.168.3.0/24 The default gateway is the ADSL modem: 192.168.1.254 Both networks can see each other, the machines on the 192.168.3.0/24 network set their gateway as the Linux box which in turn forwards their traffic to it default gw 192.168.1.254. The script uses 'iproute' and 'iptables'. Any feedback much appreciated. Thanks. Kind regards, Rudi.
