I likely know the answer but WAN IP over 5G?

Legacy0 · ‎03-07-2025

I have a 5G device with SIM and want to know If I can get a full IPv4 WAN not CGNAT with inbound traffic to me can EE do this? Or is it a big no and is CGNAT only with this type of network?

Thanks

A big NO! You do get a public external IP addy but it is not unique to you.

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.

Yes but technically it can be done its just that IPv4 has limited IP's addresses I mean their be no problem giving everyone a full IPv6 address by 4/5G.

I guess what I was thinking is EE could in some way at extra cost to do this? I mean how it could be done is by APN with authentication username and password to access a DHCP server giving out a WAN IP.
