For CG-NAT you don't actually get any inbound ports, so dynamic DNS won't help you.

That being said, I know some ISPs over here that will block standard ports inbound beyond SMTP when you're not behind CG-NAT. I can imagine that leading to some who are just starting giving up when they've followed all the instructions to get HTTP on port 80 working and it still doesn't work without explanation.

OK, fair point. Forgot about CG-NAT, but dyndns still meant I was able to access stuff remotely despite not having a static IP.

Yep, it's not a problem if you know how it works and don't have CG-NAT.

My point is that newbies don't know, and whilst the IP rotation problem might force some of them to learn about DNS, it will also put a bunch of people off entirely.
