Install and Configure a StrongSwan Gateway VPN Server on Ubuntu 20.04

StrongSwan is an open-source tool that operates as a keying daemon and uses the Internet Key Exchange protocols (IKEv1 and IKEv2) to secure connections between two hosts. In this way, you can use StrongSwan to establish a Virtual Private Network (VPN). VPN connections from a client to the StrongSwan server are encrypted and provide a secure gateway to other resources available on the server and its network. This guide shows you how to install and configure a StrongSwan gateway VPN server on Ubuntu 20.04. You also learn how to set up and connect to a StrongSwan server from an Ubuntu, Windows, and macOS client.

What is WireGuard?

WireGuard® is a simple, fast, and secure VPN that utilizes state-of-the-art cryptography. With a small source code footprint, it aims to be faster and leaner than other VPN protocols such as OpenVPN and IPSec. WireGuard is still under development, but even in its unoptimized state it is faster than the popular OpenVPN protocol.

Configuring a VPN Kill Switch on OpenVPN Clients Using iptables

A virtual private network is often used to evade censorship, surveillance, or geolocation by routing internet traffic from your local device to the remote VPN server through an encrypted tunnel. In this scenario, the VPN server is the internet gateway for all connected client devices, and it forwards traffic from clients out to the internet, then receives and routes the traffic back to the client devices. However, there is always a risk that the VPN connection will unexpectedly drop, which can result in your traffic being communicated over the public internet instead of through the encrypted VPN connection.
