OpenVPN Server: Set up your own VPN server

Complete tutorial to install and configure an OpenVPN server, in order to create a secure virtual private network.

Back to tutorials
What is a VPN?
A VPN (Virtual Private Network) creates a secure, encrypted "tunnel" for your internet traffic. This protects your data from prying eyes on unsecured networks (such as public Wi-Fi) and lets you access resources on a remote network as if you were physically there. OpenVPN is one of the most robust and reliable solutions for creating a VPN server.

Why use OpenVPN?

  • Open-Source and Audited: The code is public and has been audited multiple times.
  • Highly Configurable: Offers very fine-grained control over encryption protocols, ports and network options.
  • Cross-platform: Clients exist for virtually every operating system (Windows, macOS, Linux, Android, iOS).
  • Solid Security: Uses the OpenSSL library and the TLS protocol for cutting-edge security.

Prerequisites

  • A dedicated Linux server (Ubuntu/Debian recommended), which will be your VPN server.
  • Root access or sudo privileges.
  • A static IP address on the server.
