I'm sharing my dorm's wifi with my XBOX 360 via ethernet connection to my Macbook Pro. I followed instructions on setting up internet sharing from Airport to computers using ethernet from http://www.joystiq.com/2006/07/17/how-to-share-your-macs-internet-connection-with-your-xbox/ However, when in the Network settings, under Ethernet, it says "Ethernet has a self-assigned IP address and will not be able to connect to the internet". So when my XBOX tries to test the connection, it can't even get past the first step in connecting to the network and says it cannot obtain an IP address. So I get the impression that I should manually assign an IP address myself, but I don't know much about networking so I don't know what IP address to use. If I use the self-assigned IP address, where should I enter that number in my XBOX network settings? under IP address or gateway? or DNS settings?
