@xandris @rds Ahh, yes. It's in the range described as:

Shared address space for communications between a service provider and its subscribers when using a carrier-grade NAT

Hmm, is there a way around that (I knew didn't have a fixed IP but I was going to use my domain providers DNS API to dynamically update the IP as required.

@thechildofroth @rds oh wait hold up

you have cg-nat which means you don't have a unique external address at all from what i understand. if you go to ip.me or similar, the address it shows you is shared with other customers. the gateway would have no way to know which customer an incoming connection should go to

all that to say...more research needed on how to receive connections when behind cg-nat. i think cloudflare offers something for this for free...
