The Raspberry Pi, with its affordability and versatility, has become a favored tool for tech enthusiasts. When combined with VPN functionality, it offers an exciting way to level up your digital privacy game. Let’s dive into how you can set up your Raspberry Pi VPN server with ease.

Setting The Stage: Preparing Your Raspberry Pi

Before you embark on your VPN journey, ensure your Raspberry Pi is ready for the task.

Initial Raspberry Pi Setup

OS Installation: Begin by installing the latest version of Raspberry Pi OS (formerly Raspbian) onto an SD card.
Connectivity: Ensure your Pi is connected to the internet, preferably via an Ethernet cable for stability.

Updating Your System

Always start with the freshest software:

Open the terminal.
Input sudo apt update and press Enter.
Follow it up with sudo apt upgrade.

Choosing Your VPN Protocol: OpenVPN vs. WireGuard

Two leading VPN protocols are suitable for Raspberry Pi: OpenVPN and WireGuard. While both offer robust security, WireGuard is newer and promises faster speeds. For this tutorial, we’ll focus on the popular OpenVPN.

Setting Up OpenVPN on Your Raspberry Pi

Transition into the setup phase with the following steps:

1. Installing OpenVPN

Execute the following in the terminal:

sudo apt install openvpn

2. Configuring OpenVPN

Download the EasyRSA script to manage your certificates. This will help in creating a secure connection.

wget -O ~/EasyRSA-3.0.8.tgz https://github.com/OpenVPN/easy-rsa/releases/download/v3.0.8/EasyRSA-3.0.8.tgz
tar xvf ~/EasyRSA-3.0.8.tgz -C ~/

Navigate to the EasyRSA directory: cd ~/EasyRSA-3.0.8/
Initialize a new Public Key Infrastructure (PKI): ./easyrsa init-pki
Build a new Certificate Authority (CA): ./easyrsa build-ca
Follow prompts and set up a password for the CA.

3. Server Configuration

Generate the server key and certificate:

./easyrsa build-server-full server nopass

Create the Diffie-Hellman parameters for enhanced security:

./easyrsa gen-dh

4. Client Configuration

For each device, generate a unique key and certificate pair:

./easyrsa build-client-full [client-name] nopass

Replace [client-name] with a name for your client device (like “laptop” or “phone”).

5. Routing and IP Configuration

Modify your Pi’s system to allow IP forwarding:

echo “net.ipv4.ip_forward=1” | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

6. Wrapping Up: Start Your OpenVPN Server

With everything set, start your VPN server with:

sudo systemctl start openvpn@server

Check if it’s running:

sudo systemctl status openvpn@server

Final Touches: Connecting Devices to Your VPN Server

Now, on each device:

Install an OpenVPN client.
Transfer the .ovpn client file from your Raspberry Pi.
Use the client to connect to your VPN server.
