How To Use Raspberry Pi As VPN Router | Complete Guide

VPNs have become so mainstream that now they are considered an essential tech tool that internet users must carry for their online security. A VPN protects your digital world and online privacy by encrypting and routing your web traffic through tunneled servers that no one can detect. It’s quite easy and convenient to configure and use a VPN app on your smartphone or PC. VPNs nowadays are compatible with all major operating systems like Windows, iOS, macOS, Android, and even Linux. We can even use a Raspberry pi as a VPN router. In this article, we will learn in-depth about Raspberry Pi as a VPN router and how we can use it.

One way around using VPN connections on these devices is to set up a Wi-Fi router with a VPN configuration. But there’s an even cheaper solution to protect your entire home network, and that is using Raspberry Pi VPNs as a router. With a few straightforward scripts, we can convert Raspberry Pi as a  VPN router. By doing this, you will be routing by redirecting your router’s traffic to the VPN gateway before it’s sent anywhere else.raspberry pi

In this guide, we will explain how to use Raspberry Pi as a VPN Router by following simple steps.

Prerequisites to use Raspberry Pi as a VPN

To get started, you’ll need the following items:

  • Raspberry Pi (1st gen or newer) operating headless (no monitor or keyboard). A non-headless Pi can also be used for this purpose, but linking remotely is much easier.router
  • A premium VPN subscription of your preferred service provider. We’ll be using NordVPN, which is undoubtedly a preferred choice of enhanced privacy advocates. However, there are several reliable VPN apps, such as ExpressVPN and Surfshark.vpn service providers
  • OpenVPN setting files of your VPN provider and its encryption certificates. Plenty of servers are usually hosted by VPN apps, so you must pick enough of them for your gateway in order to connect quickly. We selected two servers from the US and two from the UK. It’s pertinent to mention that one of them must support the UDP protocol while the other one must support TCP/IP. These OpenVPN setups are easily accessible via your VPN provider’s official website. On your PC, download the files and then extract them. 

Once you’ve resolved these issues, proceed as follows:

  1. Sign into your Raspberry Pi and open its command prompt. In case you have a headless Pi, you must connect through SSH.
  2. Now, type “sudo apt-get install openvpn” to configure the OpenVPN packages. To confirm, type “Y” followed by a click on Enter.sudo apt-get install openvpn
  3. Enter “cd /etc/OpenVPN” to navigate to the OpenVPN setup files folder. cd :etc:openvpn
  4. Download the OpenVPN configurations from the website of your VPN service provider.openvpn configurations
  5. We did it by using “wget” but you must use “sudo” as ordinary users can’t write it.

A prompt “ls” command demands analyzing and shows if you have successfully done that. There is supposed to be a short list of files with the .ovpn file extension. Please note that some VPNs may have stored these files in subdirectories. For instance, for connections secured and encrypted with 128-bit or 256-bit protection. Your job is to move these configuration files in an “etc/openvpn” directory via mv command.ls command

  1. Establish a connection with any of the servers for which you downloaded OpenVPN files through the command “sudo openvpn example.ovpn.” You can replace “example” in this command with any file name of your VPN. You will then be asked by the script to enter your email address and password if you want to validate the connection. Run the “ifconfig” command and test if it’s working fine.

  1. Go through all these steps with the preferred VPN connections that you saved and think will frequently use in the future.
