Hello I am wondering if there is increased network/packet security by connecting to a server over ssh through a VPN hosted by that same server as opposed to without first tunneling by VPN. I imagine with or without tunneling through a VPN there would be latency/speed differences too?

    This is the first that I have heard about setting the SSH port to only accept connections from the VPN, is there a term or something I can search about this online? Or is this basically just allowing port 22 open on a device and not forwarding the port on the router as when a different device tunnels into the same network through the VPN it can already talk to the first device?

      You would either configure the Linux firewall of the router or server to drop everything on the SSH port not from the VPN IP/interface or change the ListenAdress in /etc/ssh/sshd , but be careful: Don’t lock yourself out!
