- Open the terminal and update the package list by running the following command:
sudo apt update
- Upgrade the installed packages by running the following command:
sudo apt upgrade
- Reboot your Raspberry Pi Zero by running the following command:
Configuring the VPN Server
Now that your Raspberry Pi Zero is up-to-date and connected to the internet, it’s time to install and configure the VPN server software. For this guide, we’ll be using the OpenVPN software. Follow these steps:
- Open the terminal and install the OpenVPN software by running the following command:
sudo apt install openvpn
- Download the Easy-RSA package by running the following command:
sudo wget https://github.com/OpenVPN/easy-rsa/archive/v3.0.8.tar.gz
- Extract the Easy-RSA package by running the following command:
sudo tar xvf v3.0.8.tar.gz
- Change the directory to the extracted Easy-RSA folder by running the following command:
- Run the Easy-RSA script to configure the VPN server:
- Generate the server certificate and key by running the following command:
./easyrsa build-server-full server nopass
- Generate the client certificate and key by running the following command:
./easyrsa build-client-full client nopass
- Generate the Diffie-Hellman parameters by running the following command:
- Copy the generated server and client certificates, keys, and Diffie-Hellman parameters to the appropriate OpenVPN directories:
sudo cp pki/ca.crt /etc/openvpn/ sudo cp pki/issued/server.crt /etc/openvpn/ sudo cp pki/private/server.key /etc/openvpn/ sudo cp pki/dh.pem /etc/openvpn/
- Configure the OpenVPN server by editing the
sudo nano /etc/openvpn/server.conf
- Add the following configuration to the
port 1194 proto udp dev tun ca ca.crt cert server.crt key server.key dh dh.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 188.8.131.52" push "dhcp-option DNS 184.108.40.206" keepalive 10 120 cipher AES-256-CBC user nobody group nogroup persist-key persist-tun status openvpn-status.log verb 3
- Save and close the
- Enable IP forwarding by editing the
sudo nano /etc/sysctl.conf
- Uncomment the following line in the
- Save and close the
- Apply the changes by running the following command:
sudo sysctl -p
- Start the OpenVPN server by running the following command:
sudo systemctl start openvpn@server
- Enable the OpenVPN server to start on boot:
sudo systemctl enable openvpn@server
Your VPN server is now configured and ready to use.
Securing Your VPN Raspberry Pi Server
To ensure your VPN server is secure, follow these steps:
- Change the default password for the
piuser by running the following command:
