Tethering to xbox help!!!!!

[MrACR101]

I am trying to connect my S3 to my Xbox 360, to play on xbox live, and it works but I cant join any online game because of my NAT type being STRICT.

Also used FoxFi

I have also tried to usb tether to my PC then connect my xbox to the pcTe but still no luck.

I have an unlimited data plan.

Any ideas?????
