4G Wifi Router

[DogOfRoh]

I have just purchased a 4G EE mini WiFi box . Works on everything great with no connection or download speed issues! I connected to my Xbox Series X, again no challenges! On attempting to join a chat with my friends it did not allow! My NAT is currently showing as "Strict" and I require it to be "Open" in order for me to do this!? Anyone have an ideas or recommendations how to get this resolved?! 

Thanks muchly

EE mobile routers are not really suitable for gaming.

You are finding yourself up against a limitation of EE's mobile network. The EE mobile network uses Carrier Grade NAT (CGNAT) resulting in a double NAT, which games consoles often object to, which means you don't get your own public IP address but share it with other users. So you can't be uniquely id'ed on the Net & therefore your LAN cannot be addressed from outside for unsolicited accesses. This is unlike fixed BB. 

If this occurs there is nowt you can do to avoid it.
