I have been a Yunohost user for several years, and during my experience, I changed my access provider, going from Free to Orange, thus saying goodbye to my fixed IP.
So I looked into setting up a VPN server, to which my YunoHost server would be connected, so that it would benefit from the VPN’s fixed IP, as well as the possibility of customizing the reverse proxy.
I tried to follow this tutorial: Homemade WireGuard VPN on a VPS server
Unfortunately, after the first step, which consists of modifying the
/etc/network/interfaces file, I no longer have SSH access to the VPS.
If you have any leads, I would be interested, because in the current
state of things, I am forced to use ddclient to update my DNS zone, and I
cannot send emails because Orange (my ISP) blocks the port 25 to fight
spam.
