You need to enabled GATEWAY in the kernel (or set the option using 
sysctl in the boot config).  The rest depends on your existing net
config.  If you are doing dynamic routing, you need to have the
machine advertise the routes.  If not, your provider needs to
add static routes.

For such a simple network, static routes are probably best, but
should you choose to grow to a rich and diverse network, gated
might be the best (it supports OSPF and BGP).  Routed in
2.1.5 and later supports Rip V2.
