Here is the setup..

Cable modem connected to a Cisco 2522..Then The 2522 is connected via a serial link to a Cisco 2501...From there I have the 2501 plugged into my 3COM hub with the rest of my network...

I am still learning so the config as been changed many times..I recently tried configing it with Ciscos configmaker...This is what I have right now...
