In this tutorial we will see how to create multiple instances on dedicated server with OpenVPN!

Depending on where you are, it happens that some ports are blocked or filtered. Rather than having each time to redo your configuration to adapt to the new port, it is easier to create a specific configuration port.

It should be noted that since the recent version of OpenVPN, the application will default launch all configurations found in the file “/ etc / openvpn” that is to say, all the files in “.conf “.

With this configuration management, the management of your VPN will be more flexible!
