![]() After executing the steps from the Initial Server Setup Guide on this server, you can follow steps 1 to 3 of our guide on How To Set Up and Configure a Certificate Authority (CA) on Ubuntu 20.04 to accomplish that. Note: While it is technically possible to use your OpenVPN Server or your local machine as your CA, this is not recommended as it opens up your VPN to some security vulnerabilities. Per the official OpenVPN documentation, you should place your CA on a standalone machine that’s dedicated to importing and signing certificate requests. For this reason, this guide assumes that your CA is on a separate Ubuntu 20.04 server that also has a non-root user with sudo privileges and a basic firewall enabled. In addition to that, you’ll need a client machine which you will use to connect to your OpenVPN Server. In this guide, we’ll call this the OpenVPN Client. With these prerequisites in place, you are ready to begin setting up and configuring an OpenVPN Server on Ubuntu 20.04.įor the purposes of this tutorial, it’s recommended that you use your local machine as the OpenVPN client. Note: Please note that if you disable password authentication while configuring these servers, you may run into difficulties when transferring files between them later on in this guide. To resolve this issue, you could re-enable password authentication on each server.

See How to Set Up SSH Keys on Ubuntu 20.04 for instructions on how to perform either of these solutions. The first step in this tutorial is to install OpenVPN and Easy-RSA. Easy-RSA is a public key infrastructure (PKI) management tool that you will use on the OpenVPN Server to generate a certificate request that you will then verify and sign on the CA Server. To start off, update your OpenVPN Server’s package index and install OpenVPN and Easy-RSA. ln -s /usr/share/easy-rsa/* ~/easy-rsa/.Now you will need to create a symlink from the easyrsa script that the package installed into the ~/easy-rsa directory that you just created: Next you will need to create a new directory on the OpenVPN Server as your non-root user called ~/easy-rsa: Both packages are available in Ubuntu’s default repositories, so you can use apt for the installation: Openvpn connect for osx download install#
