Hi All,


I have a Debian Apache Server running on a machine under my home network. I have a opnevpn client and a AirVPN host running especially for the server. But all the incoming connections over ports 80 (http) and 443 (https) are not accessible now from the publicly assigned IP address by AirVPN.

I have tried port forwarding some arbitary port >2048 to internal port 443 using Remote Port Forwarding and it works fine. But now I wanted to have a SSL certificate provided by https://letsencrypt.org/ but their client only checks and updates the certificates over SSL port 443 and that is true for all the SSL certificate providers. Is there any I can get the requests go through the VPN?

You can obtain a LetsEncrypt certificate using other domain validation methods, like DNS validation.

Look at this thread for example:




In any case, you will have to use a high port with your server, it won't be possible to forward 80/443 on the VPN IPs.
