How to Setup CyberGhost on OpenVPN on DD-WRT Routers

Here is a detailed step-by-step guide that will enable you to do a CyberGhost router setup on OpenVPN on DD-WRT routers.

Step 1

Ensure that your DD-WRT router is connected to the internet. Go to your Router Management Console by entering your router management address. It is usually if you haven’t changed it manually.

  1. Go to the ‘Setup’ section and click ‘Basic Setup’. Ensure that ‘connection type’ is set to ‘Automatic Configuration DHCP’. Next, set a Local IP address by going to the ‘Network Setup’ and setting up the ‘Local IP address.’ Now, you can use this address to access your Router Management Console.
    Note: It will work okay if ‘Automatic Configuration’ is set as default. If your ISP has changed the settings, then tweak this.
  2. Go to ‘Setup’ and then to IPv6 support, click Disable, and save the settings.


Step 2

Go to the CyberGhost website and Log In by entering your username and password for your CyberGhost router connection.


  • Click on ‘VPN’ from the menu on the left, click “Configure Device,” and then follow these points.



  • Set the Protocol to OpenVPN to start the CyberGhost OpenVPN router setup.
  • Select the desired country from where you want to surf the internet. CyberGhost will automatically choose the best server for your CyberGhost router connection.
  • Select the server group and the OpenVPN Protocol according to your choice.

Download the configuration by clicking on “Download Configuration.” Make a proper location on your computer to extract the zip file you downloaded.

  • A ca.crt file, which is the certificate from the certification authority.
  • A client.crt file, which is the user certification file.
  • A client.key file, which is your private key file
  • An openvpn.ovpn file, which is your OpenVPN configuration file.

Step 3

  • PKCS12 Key: leave blank
  • Static Key: leave blank
  • CA Cert: Copy all the content in the “CA.crt” file, just like we did with the openvpn.ovpn file above and paste it into the given box.
