To pair Pi-hole with an OpenVPN on an Ubuntu or Debian Linux system, you will need to install and configure both programs.
To install Pi-hole, follow the instructions in the Pi-hole documentation. This will typically involve running a script that installs Pi-hole and its dependencies.
To install OpenVPN, follow the instructions in the OpenVPN documentation. This will typically involve adding a repository to your system and installing the OpenVPN package.
To configure OpenVPN, you will need to create a configuration file and specify your VPN provider's server information. You can find examples of OpenVPN configuration files in the OpenVPN documentation.
To configure Pi-hole to use OpenVPN, you will need to edit the Pi-hole configuration file and specify the path to the OpenVPN configuration file. You can find more information on how to do this in the Pi-hole documentation.
Once you have configured both Pi-hole and OpenVPN, you will need to restart both programs for the changes to take effect. To do this, you can use the systemctl command. For example:
sudo systemctl restart pihole-FTL sudo systemctl restart openvpn@server
Pi-hole should now be configured to use OpenVPN to block ads and increase privacy on your Ubuntu or Debian Linux system.
