Ok so here is my situation, I am living in a dorm room that requires me to register my computer's ehternet address in order for the Internet to work. So right now i have my mac hooked up to the internet through an ethernet wire. Is there anyway i can share my internet to my xbox? Is it possible to have it look like this? Internet --> Mac --> (wirelessly) airport base station --> (wired) xbox (form the ethernet connection port?
