Ok, so here's the problem. I have an xbox360 that I want to get online, but getting it close enough to my physical internet connection really isn't an option. I do not have a wireless router in my house. I do have a MacBook running OS X 10.4.11 and an old PowerBook G4 running OS X 10.4.11 both with Airport cards. What I want to do is have one laptop share the wired connection via Airport. The other laptop would get on that Airport network and share it to the 360 via ethernet. I've looked online and saw tutorials for getting it to work if you're using a wireless router, but none involving two macs like this. Following the tutorials that aren't specifically what I want, it's gotten as far as the DNS step when it tests the connection. Any help you guys can give would be great. I'll try and give any other information you guys might need. Just ask.
