What type of NAT type do you get when you do a internet test connection? I am getting a type 3, which it says certain game features will be restricted. I had to look it up in the user guide. If that's thecase it could be certain firewalls or like I said the ISP. Unfortunately I'm stuck on base so idk what ISP it has, but from other threads I can only hope when I get out in town with a different ISP it should work.
