Add VPN Devices

Firstly, if you don't know what VPN is, below you can read a little description you can find on the Internet.

A virtual private network, or VPN, is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely transmitted. It prevents unauthorized people from eavesdropping on the traffic and allows the user to conduct work remotely.

The main purpose of setting up the VPN access is to let the user safely connect to his DAppNode in case he wants to access it remotely.

DAppNode is compatible with 2 kinds of VPN clients. Wireguard and OpenVPN. This process has three parts:

Prerequisites.
Create the configuration file and select the client.
Set up the client in the device you want to use to access your DAppNode.
