Setting Up DDNS on No-IP and Installing WireGuard VPN Using PiVPN on Port 1337

In this tutorial, we'll walk through setting up Dynamic DNS (DDNS) on No-IP and installing WireGuard VPN using PiVPN on a Raspberry Pi. This guide assumes you have basic knowledge of Linux commands and network configurations.

Prerequisites

  • A Raspberry Pi with Raspbian installed
  • A No-IP account
  • Internet access
  • A public IP address

Step 1: Setting Up DDNS on No-IP

Dynamic DNS (DDNS) allows you to map a dynamic IP address to a static hostname. This is useful if your ISP changes your IP address frequently.

1.1 Create a No-IP Account

  1. Go to No-IP's website and sign up for a free account.
  2. Confirm your email address.

1.2 Create a Hostname

  1. Log in to your No-IP account.
  2. Navigate to Dynamic DNS > Add Hostname.
  3. Enter a hostname (e.g., myhome.no-ip.org).
  4. Select a domain.
  5. Click Save Hostname.

1.3 Install the No-IP DUC (Dynamic Update Client)

  1. Open a terminal on your Raspberry Pi.

  2. Download the No-IP DUC:

     cd /usr/local/src
 sudo wget https://www.noip.com/client/linux/noip-duc-linux.tar.gz
 sudo tar xf noip-duc-linux.tar.gz
 cd noip-2.1.9-1
 sudo make
 sudo make install

  3. Configure the No-IP DUC:

    sudo /usr/local/bin/noip2 -C

  4. Enter your No-IP account credentials when prompted.

  5. To start the No-IP DUC client:

    sudo /usr/local/bin/noip2

  6. To ensure it runs on startup, add the following to /etc/rc.local:

    sudo nano /etc/rc.local

    Add before the exit 0 line:

    /usr/local/bin/noip2

Step 2: Installing WireGuard VPN Using PiVPN

WireGuard is a modern, fast, and secure VPN protocol. PiVPN makes the installation of WireGuard easy.

2.1 Update Your System

  1. Update and upgrade your system: 
    sudo apt update
sudo apt upgrade -y

2.2 Install PiVPN

  1. Install PiVPN: 
    curl -L https://install.pivpn.io | bash
  2. Follow the on-screen prompts:
    • Select WireGuard.
    • For the local user, select the default user (e.g., pi).
    • When prompted for the port, enter 1337.
    • Confirm and proceed with the installation.

2.3 Configure Your Router

  1. Log in to your router's web interface.
  2. Navigate to the port forwarding section.
  3. Add a new rule to forward UDP port 1337 to the internal IP address of your Raspberry Pi.

2.4 Generate WireGuard Client Configuration

  1. On your Raspberry Pi, generate a new client profile: 
    pivpn add
  2. Follow the prompts to create a client profile (e.g., myclient).

2.5 Retrieve the Configuration File

  1. The configuration file will be saved in /home/pi/configs/ (or the home directory of the selected user).
  2. Transfer the configuration file to your client device (e.g., via SCP, email, or USB drive): 
    scp pi@your_pi_ip:/home/pi/configs/myclient.conf /local/path/

2.6 Install WireGuard on Your Client Device

  1. Install the WireGuard app on your client device (available for Windows, macOS, Linux, iOS, and Android).
  2. Import the configuration file myclient.conf into the WireGuard app.

2.7 Connect to Your VPN

  1. Open the WireGuard app on your client device.
  2. Select the imported configuration and connect.

Conclusion

You have successfully set up Dynamic DNS with No-IP and installed WireGuard VPN using PiVPN on port 1337. Your Raspberry Pi is now ready to provide secure VPN access with a consistent hostname.
