Physically, you can just plug them together. If they are gigabit interfaces they will automatically handle the crossover part. And you can use iptables on the internet-connected box to NAT the outbound connections. However, the common and simple approach is to use a home router that will typically provide 4 ethernet connections on the LAN side plus wifi for your phone/tablet/laptop. -- Les Mikesell lesmikesell at gmail.com
