Welcome to Part Two of ReadWrite’s Raspberry Pi VPN server tutorial!
By now, it’s pretty apparent that turning your Raspberry Pi into a Virtual Private Network is an all-evening activity. But as security flaws further compromise our Internet lives, it feels increasingly worth it to have a secure server on your side. That way, you’re free to write emails and transfer data without worrying about what or whom might be intercepting it as it travels from your computer to the Web.

If you’ve followed the steps from Part One of this tutorial, you’ve got a fully functional VPN server on your Raspberry Pi. You can use this to connect securely to your home network wherever there’s an unencrypted wireless connection. You can also access shared files and media you keep stored on your home network.
Only, you can’t access those files just yet. We’ve created keys for clients (computers and devices) to use, but we haven’t told the clients where to find the server, how to connect, or which key to use.
If you remember, we created several different client keys for each of the devices we want to grant VPN access. We called them Client1, Client2 and Client3.
It’d be a lot of trouble to generate a new configuration file for each client from scratch, which is why we’ll use an ingenious script written by Eric Jodoin of the SANS institute. Instead of generating a file for each client on our own, this script will do it for us.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
