Your network is setup up like this, correct ?
Cable Modem -> Linux -> WindowsXP

Because, according to the output of ifconfig, you only have one Ethernet card in your Linux PC.
Are you using a Hub that connects both PCs to the cable modem ?

Please re-exeplain your home network setup.

I think i'm using a hub that connects both pc's to the cable modem.

I turned the modem off, everything off, then turned in on and let it establish a connection before I turned my linux machine on. Should I post my new ifconfig?

Go ahead and post the new ifconfig

This setup will not work.
Why? Because your ISP is most likely providing you with only one IP via DHCP.
So only one PC can be connected to the internet at a time.

There are two ways to setup a home network.
1. Get a router. The router will act as a gateway, firewall and DHCP server for your two PCs.

2. Setup Linux as the default gateway. For this setup, you will need two network cards.
Then simply follow the steps from the thread (guide) you posted early. (hey, it's my thread )

The advantage here is that Linux acts as the gateway and firewall.
There have been some security flaws with some Home Routers recently, so it may be preferable to use Linux... and we all love Linux.

Okay, so I'll buy a router..

Does anyone know a good cheap one for linking a Linux and a PC? Or will any router that I can find on ebay/best buy work?

Linksys is a good brand. I had no problems running both my machines from the (<$50) Linksys router/firewall out-of-the-box. Make sure you're using the ethernet port on the cable modem, and then just hook the two machines into the router. Administrative tasks are simple and usually handled through a web interface (usually at http://192.168.1.1). Firewalls/routers with 802.11b (WiFi) capability are usually about $20 more, but you need a WiFi card/interface for each PC on the WiFi network.
