Sadly, cell provider puts me behind an IPv4 CGNAT, they didn't even bother to hand out IPv6 addresses at least. I picked them out because they were cheap more than anything, so I only have myself to blame.

I have previously used carriers that did expose (IPv6) addresses, though. Port 25/53/etc were blocked but I could host a web server on there if I wanted to drain the 2GB of mobile data I had at the time.

NAT isn't a problem with IPv6 support. Of course there's the network firewall, but adding a rule to accept ports 1714-1764 isn't that hard.

Right now I've solved the problem with a VPN tunnel, but that's not really that permanent a solution.
