How to Set Up WireGuard VPN on Ubuntu 18.04

WireGuard is a modern VPN (Virtual Private Network) technology with state-of-the-art cryptography. Compared to other similar solutions, such as IPsec and OpenVPN, WireGuard is faster, easier to configure, and more performant. It is a cross-platform and can run almost anywhere, including Linux, Windows, Android, and macOS. Wireguard is a peer-to-peer VPN; it does not use the client-server model. Depending on its configuration, a peer can act as a traditional server or client.

WireGuard works by creating a network interface on each peer device that acts as a tunnel. Peers authenticate each other by exchanging and validating public keys, mimicking the SSH model. Public keys are mapped with a list of IP addresses that are allowed in the tunnel. The VPN traffic is encapsulated in UDP.
