  • Debian: This is a good all around operating system for your Raspberry Pi.

Recommendation: We recommend Raspberry Pi OS for ease of use and compatibility.

Downloading and Flashing the Operating System

  1. Download the OS Image: Download the latest Raspberry Pi OS image from the official Raspberry Pi website (https://www.raspberrypi.com/software/).
  2. Flash the Image to your SD Card: Use a tool like BalenaEtcher or the Raspberry Pi Imager to flash the downloaded image onto a microSD card. Ensure you select the correct drive for your SD card to prevent data loss.

Initial Raspberry Pi Configuration

  1. Insert the SD Card: Insert the flashed microSD card into your Raspberry Pi.
  2. Connect Peripherals: Connect a monitor, keyboard, and mouse to your Raspberry Pi. If you prefer headless setup, you can do so using SSH and Wi-Fi configuration.
  3. Power On: Connect the power supply.
  4. Initial Setup: Follow the on-screen prompts to configure the operating system. This includes setting up your user account, timezone, and Wi-Fi connection if using Wi-Fi.

Updating Your System

Ensure your system is up-to-date before proceeding. Open a terminal and run the following commands:

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

Installing NordVPN on Your Raspberry Pi

Now, we’ll install the NordVPN client on your Raspberry Pi. The steps will vary depending on the distribution you choose. This guide offers comprehensive installation instructions.

Downloading the NordVPN Package

Visit the NordVPN website (https://nordvpn.com/) and navigate to the instructions section. Download the appropriate package for your operating system architecture (ARMv6 for Raspberry Pi). This is crucial for a smooth installation process. The most common package will be a .deb file.

Installing the NordVPN Client

  1. Navigate to the Downloads Directory: Open a terminal and change your directory to the Downloads folder where you downloaded the package.

  2. Install the Package: Use the appropriate package manager command. For Debian/Raspberry Pi OS, use dpkg:

    sudo dpkg -i <nordvpn_package_file.deb>
    sudo apt-get install -f # Fix any dependencies
    

Authenticating with NordVPN

Once installed, you need to authenticate with your NordVPN account. Use the following command:

nordvpn login

Enter your NordVPN credentials when prompted.

Configuring Your Raspberry Pi as a NordVPN Gateway: The Core of the Operation

This is the heart of the matter. We will configure your Raspberry Pi to route all network traffic through your NordVPN connection.

Establishing a VPN Connection

Connect to your desired NordVPN server:

nordvpn connect <country_code> # Replace <country_code> with the desired country

You can also specify a city or server number for more specific targeting. For example:

nordvpn connect us888 # This will connect to server number 888 in USA.

Enabling IP Forwarding

To allow your Raspberry Pi to forward traffic, you must enable IP forwarding:

sudo nano /etc/sysctl.conf

Add or uncomment the following line:

net.ipv4.ip_forward=1

Save and close the file. Then, apply the changes by running:

sudo sysctl -p

Setting Up Network Address Translation (NAT)

NAT is vital for allowing devices on your internal network to access the internet through the VPN connection. We will configure iptables for this purpose:

sudo iptables -t nat -A POSTROUTING -o <vpn_interface> -j MASQUERADE
sudo iptables -A FORWARD -i <vpn_interface> -o eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A FORWARD -i eth0 -o <vpn_interface> -j ACCEPT

Replace <vpn_interface> with your NordVPN interface name. This is usually nordlynx if you’re using WireGuard or tun0 or ppp0 if you’re using OpenVPN.

Important: To identify the correct interface name, you can use ip link show after connecting to NordVPN.

Persisting Iptables Rules

The rules you’ve set up with iptables will not survive a reboot. To make them permanent, you will need to use a tool to persist these rules. Here is a common method:

  1. Install iptables-persistent

    sudo apt-get install iptables-persistent
    
  2. Save the Rules

    sudo netfilter-persistent save
    

This tool will automatically reload your iptables rules on startup.

Troubleshooting Common Issues and Optimizing Your Setup

Now that your gateway is set up, you may encounter some challenges. Here is how to troubleshoot them effectively and optimize for performance.

Confirming Your External IP Address

A crucial step is confirming that your external IP address reflects the VPN server’s location. Use a website like https://whatismyipaddress.com/ or https://www.iplocation.net/ from a device connected to your Raspberry Pi’s network to verify that your IP address has changed.

Verifying DNS Leak Protection

DNS leaks can expose your true location. To test for DNS leaks, visit a website such as https://www.dnsleaktest.com/ from a device connected to your network. If the test results show your ISP’s DNS servers, there’s a DNS leak.

To fix this, configure your Raspberry Pi to use NordVPN’s DNS servers or other reputable DNS servers.

Configuring DNS Servers

  1. Edit /etc/dhcpcd.conf:

    sudo nano /etc/dhcpcd.conf
    
  2. Add or Modify the Following Lines:

    interface eth0
    static domain_name_servers=103.86.96.103 103.86.99.103 # NordVPN's DNS servers
    

    Or, if you prefer Google’s public DNS:

    interface eth0
    static domain_name_servers=8.8.8.8 8.8.4.4
    

    Replace eth0 with your active Ethernet interface.

  3. Restart the DHCP Client:

    sudo systemctl restart dhcpcd
    

Netflix, YouTube, and Geo-Restriction Bypassing: The Ultimate Goal

If you are encountering problems accessing geo-restricted content, ensure the following:

  1. Verify IP Address and DNS: Double-check that your IP address and DNS settings correctly reflect your desired VPN server location.
  2. Clear Browser Cache and Cookies: Sometimes, cached location data can interfere. Clear your browser’s cache and cookies, or use a private browsing window.
  3. Try Different Servers: Some servers may be blocked by certain streaming services. Experiment with different NordVPN servers within the same country to find one that works.
  4. Consider a Dedicated IP: If you consistently experience problems, consider using a dedicated IP address offered by NordVPN. This can sometimes bypass stricter geo-restrictions.

Performance Optimization

For optimal performance:

  • Choose Servers Closest to Your Location: This reduces latency and improves speed.
  • Experiment with Protocols: If you encounter slow speeds, try switching between NordVPN’s different VPN protocols (OpenVPN, WireGuard) using the nordvpn set protocol <protocol> command.
  • Upgrade Your Raspberry Pi: If your Raspberry Pi is struggling, consider upgrading to a newer model with more processing power.
  • Optimize Your Network: Make sure your home network is running smoothly and that your router is capable of handling the traffic load.

Advanced Configuration: Beyond the Basics

This section covers advanced settings that will enhance your experience and flexibility.

Implementing a Kill Switch

A kill switch is an essential security feature that disables your internet connection if the VPN connection drops. This prevents your real IP address from being exposed. Implementing this requires a bit more advanced configuration. Here is how you can do it:

  1. Install ufw (Uncomplicated Firewall):

    sudo apt install ufw
    
  2. Configure ufw:

    sudo ufw default deny outgoing # Block all outgoing traffic by default
    sudo ufw allow out to 127.0.0.1 # Allow traffic to the loopback interface (necessary for some internal processes)
    sudo ufw allow out on <vpn_interface> # Allow traffic through the VPN interface
    sudo ufw allow 53/udp # Allow DNS resolution
    sudo ufw allow 53/tcp # Allow DNS resolution
    sudo ufw enable # Enable the firewall
    

    Remember to replace <vpn_interface> with your VPN interface name.

  3. Testing the Kill Switch:

    Disconnect your VPN connection to test your kill switch. Your internet should be blocked. If it is not, review your configuration carefully.

Automating VPN Connection on Boot

To automate your NordVPN connection on startup:

  1. Create a Systemd Service File:

    sudo nano /etc/systemd/system/nordvpn-autostart.service
    
  2. Paste the following content into the file and adjust accordingly:

    [Unit]
    Description=NordVPN Autostart
    After=network-online.target
    Wants=network-online.target
    
    [Service]
    Type=oneshot
    ExecStart=/usr/bin/nordvpn connect <country_code> #Replace <country_code> with your desired country
    RemainAfterExit=yes
    
    [Install]
    WantedBy=multi-user.target
    
  3. Enable the Service:

    sudo systemctl enable nordvpn-autostart.service
    sudo systemctl start nordvpn-autostart.service
    

Monitoring Your VPN Connection

Monitor your VPN connection and logs:

  • Use the nordvpn status command to view your current connection status.
  • Check the NordVPN logs located in /var/log/nordvpn.log for any errors or warnings.
  • Utilize a monitoring tool (like top or htop) to check resource usage on your Raspberry Pi.
