Hi, a guy at EE recommended that I messaged you for help. I have 4GEE mobile broadband. I've just connected my PS4 to the router and it is showing NAT3 via WiFi and LAN. Is there any way I can change this to NAT2? I've got a repeater but that hasn't worked either. I've also tried setting up DMZ but that hasn't worked. Would be grateful of a fix for this. Thanks- Oli

@Olafurd : I can't think who in EE would've told you to address me. I'm just a user like you.

It's likely that you've come up against a limitation of EE's mobile network. The EE mobile network uses Carrier Grade NAT (CGNAT), which means that 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.

Thank you. Called 150, spoke to tech support on option 2 then 2 and the adviser said to speak to you on community as you would know a fix and to get back to them if I had spoken to you and didn't have a solution. Sorry to have bothered you! Not sure why they are advising this if you're not part of EE in a formal capacity!!
