OpenVPN is software that can be used to easily set up virtual private networks (VPN) via a secure connection. Typical applications for a VPN are, for example, the connection of two company locations over the internet, or the connection of field employees to the corporate network. For encryption, OpenVPN uses OpenSSL. The software is compatible with Linux, Solaris, various BSD derivatives, and Microsoft Windows 2000/XP.
OpenVPN is free software and is available for download on the project page .
