How To Set Up and Use NordVPN on Fritz!Box (Updated 2024)

Fritz!Box makes internet connectivity a lot more convenient and manageable at home or the office. One Fritz!Box unit serves as a router and modem. This device is manufactured by the German company AVM.

Like most routers, Fritz!Box already has its security system. However, you can still use a VPN to improve your security and privacy while connected to the internet. NordVPN is one of the best VPN providers because it offers reliable, fast internet connections, top-notch security, and anonymity.

However, you cannot install NordVPN directly to a Fritz!Box router. Instead, you will have to install the VPN on a VPN-compatible router (DD-WRT or Tomato firmware) or install the app on devices you connect to the Fritz!Box. In this article, we’ll show you the setup process for each method.

How To Set Up NordVPN on a DD-WRT Router for Fritz!Box

DD-WRT is a custom firmware for routers that can implement the OpenVPN protocol, and there are so many routers that use this firmware today. The following steps will guide you through setting up an OpenVPN connection on your DD-WRT router for your Fritz!Box:

1. Configure The Router

The only thing you’ll need to do is to go to the DD-WRT Administrative Interface. From there, navigate from ‘Setup’> ‘Basic Setup.’ Under the ‘Network Address Server Settings (DHCP),’ set the following:

Static DNS 1:

Static DNS 2:

Static DNS 3: (default)

Use DNSMasq for DHCP: Checked

Use DNSMasq for DNS: Checked

DHCP-Authoritative: Checked

Finally, save and apply the settings.

2. Disable IPv6

To disable IPv6, Head back to the ‘Setup’ page and navigate to ‘IPv6’. Set IPv6 to ‘Disable,’ then click ‘Save’ and then ‘Apply Settings.’ This is important to ensure that your IP address doesn’t leak once connected to a NordVPN server.

3. Enable the OpenVPN Client

Next, click on ‘Service’ and then navigate to ‘VPN.’ Then, you’ll see the ‘OpenVPN Client.’ Click on it, and toggle the ‘Start OpenVPN Client’ option to ‘Enable.’ This will show you the suitable options for this setup. Next, set the following:

Encryption Cipher: AES-256-CBC

Hash Algorithm: SHA-512

User Pass Authentication: Enable

Username, Password: Your NordVPN service credentials

First Data Cipher: Not set

/usr/bin/killall openvpn

/usr/sbin/openvpn –config/tmp/openvpncl/openvpn.conf –route-up /tmp/openvpncl/ –down-pre /tmp/openvpncl/ –daemon

You’re to replace ‘YOURUSERNAME’ and ‘YOURPASSWORD’ with your corresponding credentials. If you don’t have your NordVPN service credentials off the top of your head, you can check your NordVPN account dashboard so you can copy the credentials directly from the page.

#Delete ‘#’ in the line below if your router does not have credentials fields

#auth-user-pass /tmp/openvpncl/user.conf

Open the OpenVPN configuration file you downloaded earlier with a text editor.

When you open the .ovpn file of the server you want to use, copy and paste the <ca> part of the file into the ‘CA Cert field.’ Include the —–BEGIN CERTIFICATE—– and —–END CERTIFICATE—– lines, but don’t copy the <ca> and </ca> tags.

Once you’ve done that, click ‘Save,’ and then ‘Apply Settings.’
