OpenVPN is a popular open-source VPN (Virtual Private Network) software application to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. OpenVPN uses a custom security protocol that utilizes SSL/TLS for key exchange, and is capable of traversing network address translators (NATs) and firewalls.

In order to connect to a VPN server based on OpenVPN, users normally use the OpenVPN Client. OpenVPN no longer provides a standalone OpenVPN Client (openvpn-client.msi) for Windows desktop operating systems. In order to install the OpenVPN Desktop Client to load the .ovpn file, you need to download the all-in-one OpenVPN GUI setup installer.

How to Download and Install OpenVPN Client on Windows
