First of all, you shouldn't use the network if it is not officially assigned to you. If it is, then you will only have to add a route for this network to your ethernet adapter, and setup all your clients to use the Linux machine as a gateway. If it is _not_ officially assigned, you should use one of the IP ranges that are reserved for local use. In both cases, make your default route point to the PPP link to your ISP.

If you use local reserved IP addresses, you will have to install either a proxyserver (like Squid), or set up your box to do IP masquerading. Proxies have to be supported by the clients, IP masquerading works in all cases, because the clients don't even notice.
