@greenhouse: Ya you must be just google port forwarding for your model of router, the string is normally set up 3695-3695 then select protocol used UDP or TCP then ip address of console or you can use all devices. If you can figure that out you can also add the console to the routers DMZ which has all ports open.
Might actually have to get a XBOX One for this game. After switching to PS4 Forza is the only title I miss playing. Probably also because there hasn't been a Grand Trismo released for PS4 yet.
