i should probably write a nice guide and publish it with yakihonne or highlighter so other people can do it, it's not difficult. there's a few prerequisites like understanding how to set up and use SSH and your SSH keys and set the VPS to allow the connection and installing the Go compiler and how to invoke it to build the reverse proxy and how to know how to find its path and the configuration path etc.

would be nice. my irish friend who commissioned me to work on indra was always talking about wireguard, he uses it to allow internet routing to his NAS, and i managed to find that setup script and with all that it's really not difficult. even, you can lock the SSH server down so it can only be accessed by someone who already has access to the wireguard VPN.

wireguard is awesome. once you learn how to use it you'll regret not having learned sooner.
