Opening a VPN Connection towards another server

Hi, I am using Plesk to manage my server and now I need to forward AMQP data towards a VPN server from my Node JS application. I have been looking into OpenVPN to install on my Ubuntu server however it still isn’t very clear how I can open/manage connections (the documentation mostly mentions connecting to another OpenVPN server not any VPN server/tunnel).

Any other recommendations please?

Tunnels and VPNs are different. In addition, there are different protocols. The easiest way I have found is to have a device always connected to the VPN, then tell that device (on the local network) to send what it needs to send. Kinda hacky, but it works.

Thanks for the heads up - In my case I need to use L2TP/IPSec. Any idea how I can implement this on an Ubuntu Server running Ubuntu 20.04.4 LTS?
