Introduction

A VPN (Virtual Private Network) is a means to extend your local private network (in your home or office) with another private network. The traffic between the systems in both networks, although it travels on the internet, is encrypted, so eavesdropping on it is impossible.

In it most simple form it gives your desktop or laptop (a one node network) access from anywhere to the network at home or your office. In this case WireGuard gives you a virtual network interface to the remote network. It looks as if your device is present in that remote network as a local device.

Configuration of WireGuard and Firewalld on both ends determines which systems locally and elsewhere are accessible.
