That article - and his predecessor http://fedoranews.org/ghenry/gateway/
-  should be helpful. Two points are typical pitfalls for beginners: the
Linux host must forward traffic between his 2 devices. This is calle
ip_forward and is to be set on (1) in /etc/sysctl.conf. The other point
is that the client(s) behind the gateway host must be able to resolve
hostnames. So they either have to have in their network setup knowledge
about the ISP's DNS addresses or if the gateway acts as a local caching
nameserver, they have to use his IP as DNS address.
