Go here for a pdf with great information about securing a machine/network....

 http://www.linuxdoc.org/LDP/gawlso/linuxsos-1.1.pdf

once you have setup the internal access(MANUAL IP) and the external access
(DHCP), remember to turn on ip-forwarding (otherwise the gateway will not allow
the internal network to address the outside world). IPChains has many
confuration tools/files ( I have tried pmfirewall http://www.pointman.org/ - it
is free ).

I have a firewall for controlling access through my cable modem ( and after
watching the ip access I am convinced everyone should have firewalling
services, at least through the same box ).

BTW - sunsite has almost every distro - and it is very fast....

Good Luck....
