I have a ATT unite pro mobile hotspot that is my only internet option for where I live (near the city so i have good speed but off the road enough that don't have cable). I can play my Xbox one online and have great speeds however i have a strict NAT that limits me joining some games and chatting. I have tried doing port forwarding, uPNP, and using dmz all without any change in NAT. I have done these with a static ip. Since it is through ATT and basically using cell phone internet is it even possible to ever get an open NAT? when i do the detailed network statistics it says I am behind a port-symmetric NAT. Can anyone tell me if it is possible to get the NAT open for this ATT hotspot and if so how?
Thank for your time and help
