swines. You will need a static ip address then if that is what they are telling you which is causing you nat restrictions. That is a bit shadey of them and I certainly wouldn't be with a company which pulls crap like that on it's customers. It looks like you are using a shared ip address.....YUK! CGNAT = Carrier Grade Nat.

I have a static ip with my ISP, but It was what I wanted and it comes in handy when accessing my files away from home etc etc 

CGNAT is used by telcos running short of public IPv4 addresses. By deploying CGNAT, a mobile network or ISP can stick a bunch of customers – typically small businesses and home subscribers – on private IPv4 addresses and route them through a small set of global IPv4 addresses.

That's really interesting, i've never come across that here in the UK but maybe they don't do it here yet?

It's like moving your router into the street cabinet so you and your neighbors are all on the same subnet, weird.
