Comment on Let’s Encrypt Begins Supporting IP Address Certificates
melmi@lemmy.blahaj.zone 3 weeks agoI don’t see how? Normal HTTP verification would still apply so you’d need port forwarding. You can’t host anything on the CGNAT IP so you can’t pass verification and they won’t issue you a cert.

You can totally host something on carrier-grade NAT using techniques like NAT hole punching.

You don’t get control of the incoming port that way. For LetsEncrypt to issue a certificate primarily intended for HTTPS, they will check that the HTTP server on that IP is owned by the requesting party. That has to live on port 80, which you can’t forward on CGNAT.
