Ok, I've got a mac laptop and I'd like to know if it's possible for me to use my machine as an ethernet bridge. The idea is to connect an xbox to the internet/network through the ethernet card and AirPort of my machine. The AirPort is connected to a wireless-g router which in turn normally gives my laptop access to the router's little private network and the internet. Can what I am asking be done with the System Preferences or a 3rd party app? I think that it should be theoretically possible, but the nuances of mac network configuration still escape me after owning one for a whole month. Thanks for the feedback in advance.
