Hello all, I've been searching for a solution to this problem for a few weeks and am convinced the answer is out there but I just don't know how to phrase the search in the correct way to get moving on this.

For various reasons I need to setup the following type of network:

Internet Connection --> Ubuntu 7.10 PC --> Wireless Router --> Everything Else

To clarify, I need the Ubuntu PC to act as a gateway (I think this is the proper terminology, correct me if I am wrong) to my ISP which can share the internet connection with my wireless router, which can then distribute the internet to all other PCs/Devices.

Why don't I just connect the router to my ISP/Modem? The short answer is that I am in a college dorm and it simply will not work. This proposed setup is an attempt at a work-around.

I have attempted a few configurations I found (for example, http://ubuntuforums.org/showthread.php?t=91370) to no avail. Any directions/advice/links would be much appreciated.
