Internet Through Another Computer
 

Hello, I'm not sure if all of this is even completely possible, but I'm sure some of you will be able to tell me.

What I want to do is set up a desktop pc running linux (Kubuntu 8.10 possibly, a buntu of some sort anyways), which will have two NIC cards. One card will connect to an Ethernet jack in my dorm room, while the other will connect to a router. From the router I will connect a second desktop running Windows Vista, as well as a laptop (dual boot vista and Ubuntu 8.04). I want the second two machines to access the internet through the linux machine. Is it possible to set up such a configuration?
