Local Service through DDNS

[jomsen 0]

Hello everyone,

I want to save myself a web hosting account and make a REST API for my home automation accessible via the AirVPN Dynamic DNS service.
The whole thing should run on an Unraid server, and it must absolutely have a TLS/SSL certificate accepted by browsers (e.g., Let's Encrypt).

Is this possible?If yes, how?

Thank you very much!

This is not possible with any offered challenge types on AirVPN.

• HTTP-01 requires port 80, TLS-ALPN-01 port 443, but users cannot forward ports <1024.
• DNS-01 requires setting TXT records in DNS, but users cannot edit the airdns.org zone.

You could bring your own domain and point it to AirVPN in A record. It would work, but since the IP is shared, I don't think it's recommended. I don't think subdomains are discoverable, so using a subdomain would be safer for this.

A better solution would be for you to host a separate VPN in your local network and expose it to Internet with AirVPN. This VPN can have it's own internal DNS and CA, or you can point A record (and TXT for DNS-01 challenge) of your domain to a private IP address

Oh, be careful with that. Subdomains are much easier to discover than directories, simply because you can use many more methods for discovery. Here are some subdomain results for airdns.org and airvpn.org.
