NordVPN OpenVPN DD-WRT Router Setup Guide

  1. Getting started:

  • If you are following this guide it means you have no problems connecting to your FlashRouter network and accessing your FlashRouter settings. 
  • If you are having trouble accessing your router settings then you can always follow our guide on how to access your router settings or if needed how to reset your router to default DD-WRT firmware settings before proceeding with your NordVPN client connection setup. 
  • Download setup files from within your account area on the NordVPN website by logging in and then clicking the Download area.
  • Scroll down and click on the DD-WRT .OVPN configuration files link. A folder will download to your computer containing a full list of NordVPN server locations. Once downloaded extract the contents of this folder to your computer.
  • Hint: Use the program Notepad++ in Windows or TextEdit in MAC OS to open view the contents of your .ovpn file. 

2. Entering NordVPN settings:

In your DD-WRT FlashRouter settings click on the Services > VPN page. Leave all settings not mentioned below as their default setting.

If you wish to disable your VPN connection simply set this to Disable at any time and click Apply Settings.

Server IP/Name

At the top of the .ovpn file you downloaded above, there is a line e.g.: 
remote 1194 (or 443) is your NordVPN server location

If you wish to change NordVPN connection location,you will need to change this field as well as the TLS Auth Key and CA Cert fields mentioned below. These new server details will be contained in a new .ovpn file.

Hint: The NordVPN Key and Certificate are NOT the same for all NordVPN server locations. If you ever wish to change your VPN server location you will need to update these two sections as well as the Server Address field mentioned above.

3. Verifying a successful VPN connection:

How can I tell if my VPN connection is active?

  1. You should now see a CONNECTED SUCCESS message on your Status > OpenVPN page.
  2. Visit to verify your new IP address and virtual location. 
    Note: In some cases you may notice that the location is not showing the same location as the server you have input in your router settings; this is because geo tracking tools are often tricked by VPN connections. As long as you see an IP address that is not the same as your normal Internet IP address then you are indeed connected to NordVPN.

4. Backing up your settings:

  1. It is always a good idea to save a backup of your working VPN settings after completing this setup, so that in the result of a reset or faulty settings change you can load your working settings in a few simple clicks.
  2. Go to the Administration > Backup page and click the Backup button. A file called nvrambak.bin will be saved to your computer. We recommend renaming this file "FlashRouter Backup" for easy searching should you ever need it.

5. Troubleshooting:

  1. If you have any issues with your connection, you can review our NordVPN Troubleshooting page.
