Enabling Home Network Access with WireGuard and FRITZ!Box using DynDNS

Enabling Home Network Access with WireGuard on FRITZ!Box using DynDNS

In this article, we will discuss how to enable access to your home network over the internet using WireGuard, a modern VPN solution. We will focus on setting up WireGuard on a FRITZ!Box router, which has built-in support for this VPN technology. Additionally, we will cover how to set up DynDNS, a dynamic DNS service, to access your home network without a fixed IP address.

Prerequisites

• A FRITZ!Box router with built-in WireGuard support
• A dynamic DNS service, such as DynDNS
• A device to act as the WireGuard server, such as a Raspberry Pi or a cloud server

Setting up DynDNS

Before setting up WireGuard, you need to set up a dynamic DNS service to associate a domain name with your home network's IP address. Here are the steps to set up DynDNS:

1. Sign up for a DynDNS account and create a new hostname.
2. Install the DynDNS client on your home network's router or a device on your network.
3. Configure the DynDNS client to update your hostname with your home network's IP address.

Setting up WireGuard on FRITZ!Box

Once you have set up DynDNS, you can set up WireGuard on your FRITZ!Box router. Here are the steps:

1. Log in to your FRITZ!Box router's web interface.
2. Navigate to the "Internet" section and click on "VPN."
3. Click on "Add VPN Connection" and select "WireGuard."
4. Enter the following information:
• Name: A name for the VPN connection
• Private Key: Generate a new private key for the VPN connection
• Endpoint Host: The domain name of your DynDNS hostname
• Endpoint Port: The port number for the VPN connection (default: 51820)
• Allowed IPs: The IP address range for the VPN connection (e.g., 10.0.0.0/24)
5. Click on "Apply" to save the VPN connection settings.

Setting up WireGuard on the Server

Once you have set up WireGuard on your FRITZ!Box router, you need to set up WireGuard on the server that will act as the VPN server. Here are the steps:

1. Install WireGuard on the server.
2. Generate a new private key for the VPN server.
3. Create a new WireGuard configuration file with the following information:

[Interface]
PrivateKey = 
Address = /32
ListenPort = 51820

[Peer]
PublicKey = 
Endpoint = :51820
AllowedIPs = 
PersistentKeepalive = 25

4. Start the WireGuard service on the server.

Testing the VPN Connection

Once you have set up WireGuard on both the FRITZ!Box router and the server, you can test the VPN connection. Here are the steps:

1. Connect to the VPN on the server using the WireGuard configuration file.
2. Test the VPN connection by pinging a device on your home network.

• WireGuard is a modern VPN solution that can be used to access your home network over the internet.
• FRITZ!Box routers have built-in support for WireGuard.
• DynDNS can be used to associate a domain name with your home network's IP address.
• Setting up WireGuard on a FRITZ!Box router and a server requires generating private and public keys, configuring WireGuard settings, and starting the WireGuard service.
• Testing the VPN connection involves connecting to the VPN on the server and pinging a device on your home network.
