Mobile BB

[JackW71]

Bought a 5g router for where I am currently living as there's no landlines. Intended to mainly use it for playing online with friends on my series X, but voice chat and party chat does not work and I have either a double nat type, a strict nat type and upnp is unsuccessful, which makes what I bought it for entirely useless. Been in to the ee shop and they said it must be the xbox and refuse to take and responsibility which us absurd, I've tried everything from port forwarding and dmz, to wired/wireless connections, absolutely nothing works and they wouldn't even allow me to return it as it works for streaming but nothing else. They said that nobody has ever complained about this before and blamed the xbox? Yet if I search online there's so many complaints.. feel like I've been lied to massively, any help?

You are probably 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.

IMHO EE the mobile network is not really suitable for gaming.

So in other words I was blatantly lied to for a sale.. as I told them what it would be for and then when I went in and complained and tried to return it they said it must be my xbox as nobody has complained about it before.. and wouldn't allow me to return it.. I mentioned it was saying double nat and asked about it being cgnat and she said she had no clue what I was talking about, do they just hire people who are clueless?
