How to use your Raspberry Pi as a VPN server
In 2019, is there anything that the mighty, $35, credit card-sized Raspberry Pi computer can't do? It seems there isn't; recent Raspberry Pi projects include a functional smartphone, a computer vision kit, and even a movie projector for a more traditional home theater experience.
A Raspberry Pi (RPi) can even be turned into a server for virtual private networking (VPN). One of the many things you can tinker with on an RPi is data communications; this is one reason why they are often called "Swiss Army knives for hackers"—and not necessarily the malicious kind.
RPis can function as servers for many projects, and if you have more than one personal computing device on a personal network, the RPi can be put to work as a dedicated server. From Minecraft servers to website hosts to IRC to network printing operations, many of these projects involve a series of software installation and configuration steps, as is the case for the RPi VPN server you'll build in this tutorial.
