change from NAT Type 3 to NAT Type 2?

[jjfgood78003]

Hi there,

I'm using an EE 5g Sim in a Huawei E6878-370 5G router.

I'd really like to be able to use PS Remote Play while away from home, with the PS5 connected to the Huawei router. However, despite port forwarding and attempting to make the PS5 IP static, I am still getting NAT Type 3 when connected to the Huawei. I think this may be the source of the remote play issue. 

Is there any known fix? @XRaySpeX appears to be particularly proficient in these matters!

Many thanks.

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 running servers.

Hi Ray,

Thank you very much for your help; I suspected as much.

New question for you, if you would be so kind:

Suppose I want to port person A's phone number to Person B's sim/contract.

Person A is on EE pay monthly, but wants to cancel their pay monthly and move their number over to Person B's contract.

Person B is 6 months into a 24 month unlimited SIM only contract, with a different number (which is irrelevant and can be committed to the flames).

Is there a simple way to do this? Will EE do this if I call them to ask?

Or would it have to be via a method I have seen you post about elsewhere: Person A ports their existing number to another network's PAYG using a PAC from EE, and then can reverse port it back to Person B's contract.

(For clarity, person A and person B are working together and have agreed to the prospective arrangement, so there is no issue of taking over the contract/payment etc.)

many thanks!

That's the only way to do it; port out A & then port back to B. It then becomes B's no.
