Hi,I am using an ID SIM in a Zyxel NR5103e 5G router. I’ve got a fast connection, but the IP address is changing every few minutes, which is causing problems with some of the services I run that rely on DDNS. They’re not updating quickly enough so I can never connect. I have tried changing the APN to id, 3mobile and three.co.uk with PDP set to IPV4, but this hasn’t helped. Does anyone have any ideas what I could try instead?ThanksGuyan

This is normal. iD Mobile, like the majority of UK networks, uses CGNAT. It's just the THREE network, as far as I know, that doesn’t, using the APN '3internet’.

Hi @guyank,Welcome to the Community!Are you in the UK or abroad?Someone from the Community may know more about this and be able to assist you further.Kash
