I've searched to try and find mac specific tether guides and am I am running in to troubles.

I've followed http://turanchox.com/?p=5
since it was the newest guide I found that was specific for mac.

I am using the tzones proxy, does that matter?

Many of the tethering guides are old and I was hesitant to try them.

Upon following the turanchox.com/?p=5 guide, I got the error in safari 3:
Error 502 - Bad Request
