@ilarioq @luca The wonders of automatic translations! Two people that don't speak each other's languages can still communicate!
The best way I'd describe Pangolin is self-hosted Cloudflare Tunnels. You need to point two DNS entries on your domain to it (pangolin and *), and it will use wireguard tunnels to make any other subdomain available to your machines.
A reverse proxy might be a bit easier to handle, especially if you already have experience with it.
Good luck!
