Using a VPN is a great way to secure your personal data from getting sniffed out on public networks. You can install a VPN server on your home network and use a VPN client on your laptop or phone. The VPN client will encrypt and secure your web traffic and send it to your home network to be processed. If you have Pi-hole running on your home network as well, your VPN clients will benefit from it’s filtering capabilities no matter where you are. For this tutorial, we will be installing Wireguard in a Docker container on a Raspberry Pi 4 running Ubuntu 18.04.4 Bionic.
