Is it possible to turn my iMac G5 into a router. Right now my iMac is hooked is just hooked up to the wall but i can make it go wireless with airport. Here is what i want to do. I want to make my mac get wireless internet(already know how to do.) and then i want to put the ethernet cord from my xbox and run it from the back of my mac to my xbox. Will this work? And how would i go about setting up the sharing and such?
