Sorry! I should have given more details. Router is a Cisco 2514 with 2 ethernet interfaces. What do you mean by what kind of router ?

The reason I put natd is because when the router gave problems, as a quick fix, I configured a gateway with natd and bridging. It worked quite well. Is it a recommended alternative to a router ? I received a personal mail recommending to use gated. Planning to study that soon. > Depends on the router it is replacing. Depends on the traffic levels. > What kind of router is it?
