ExpressVPN 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 ExpressVPN client connection setup. 
  • Download setup files from within your account area on the ExpressVPN website by logging in and then clicking the Set Up ExpressVPN button, this will open a new page.
  • Scroll down and click on the Manual Config section to display your VPN Username and Password.
  • You can then choose your ExpressVPN server locations and click on any server location to download your configuration file(s).
  • Hint: Use the program Notepad++ in Windows or TextEdit in MAC OS to open view the contents of your .ovpn file. 

2. Entering ExpressVPN settings:

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

* Here are several popular ExpressVPN server addresses. Note this is only a small fraction of available servers, all other locations can be found in your .ovpn file download area on the ExpressVPN website.

North America:




Hint: ExpressVPN Keys and Certificates are the same for all ExpressVPN server locations. If you ever wish to change your VPN server location you DO NOT need to update this section. The only times you will need to update this section is if you create a new ExpressVPN account or if ExpressVPN changes the configuration of there servers. 

3. Verifying a successful VPN connection:

  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 ExpressVPN.

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 a faulty setting 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 ExpressVPN Troubleshooting page.
