Okay, I've got a problem. I'm at college, and we have this campus security thing called SmartEnforcer. I think it is what is affecting my connection to XBL. I can sign on, but it's so laggy I can't play. What I'm wondering is if there is a way to get around this smartenforcer. I've tried fiddling with my MAC address and sharing an ethernet port (on a Mac Pro), but nothing has worked for the better. Anybody got any suggestions?
