I have my xbox 360 connected to my macbook through ethernet. On my mac i have internet connection sharing enabled from airport to ethernet. Everything works fine apart from the xbox saying I have a strict NAT. I made sure the ports were all configured to work with my router, and UPnP is defiantly enabled on my router. I even tested to see if it was something to do with my firewalls, but even with them turned off, I still get this NAT error. What can I do to turn the NAT from strict to open?
