This also applies to those of us who live/work behind a proxy that requires a login. If I could access the internet via my Mac, which is connecting through the proxy, I'd be able to then access Xbox Live on my console.

Does anyone know how to setup my Xbox 360 to connect with my Mac through the ethernet port so it will use the Mac network settings instead of trying to access the proxy directly?

Additional info:
I've been able to connect the Xbox 360 to my Airport Extreme Base and it is assigned an IP/DNS from the base but then won't access the proxy.

I've setup Internet Sharing on my PowerBook 10.4.11 bridging the Airport Base to the Ethernet and setup manual IP/DNS in Xbox network settings based upon ifconfig en0/en1 inet addresses. This allows the Xbox to pass the IP/DNS tests but then hangs up on the MTU because instead of accessing the internet via my Mac Network settings, it's trying to go directly to the internet hence stumbling at the proxy.

Any suggestions/hints would be GREATLY appreciated. :-)

Mac OS X's System Preferences Internet Sharing GUI is lame. You're better off using from the command line daemon it uses anyways: natd, the NAT (Network Address Translation) Daemon. Basically, "Internet Sharing" is what Apple calls a NAT, port-forwarding router (read this: http://www.cyberciti.biz/faq/howto-configure-macosx-as-nat-router/ ).

I'm working on configuring it on my machine. I haven't found a perfect solution, but maybe those links will help.

Read about Transparent Proxying. I think that's what you want.

I started a thread here: http://forums.macosxhints.com/showthread.php?p=578715
It look like using SSH's SOCKS (-D) port forwarding's "bind address" would work for one machine. I think this is the simplest solution. That program I mentioned earlier was lame. This is all assuming you have SSH access to your proxy server.
