XBox 360 Live + Airport Express

[seelab]

Does anyone know how i could connect my xbox 360 to the internet?

My G5 is connected via airport express and my xbox 360 is connected to my G5 with ethernet cable. I'm a noob when it comes to network configurations and i really have no idea how to setup this. Please, help me...

this is what i did. Since my Tv and Xbox were next to a cable outlet ( i have cox highspeed) i put my wireless router in the tv cabnet and plugged my xbox directly into the router. Then my iMac just uses the airport to connect to the router..
