OpenVPN is a full-featured SSL VPN which implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or username/password credentials, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface. OpenVPN is not a web application proxy and does not operate through a web browser.

OpenVPN 2.0 expands on the capabilities of OpenVPN 1.x by offering a scalable client/server mode, allowing multiple clients to connect to a single OpenVPN server process over a single TCP or UDP port. OpenVPN 2.3 includes a large number of improvements, including full IPv6 support and PolarSSL support.


The OpenVPN management interface allows a great deal of control over a running OpenVPN process. You can use the management interface directly, by telneting to the management interface port, or indirectly by using an OpenVPN GUI which itself connects to the management interface.

To enable the management interface on either an OpenVPN server or client, add this to the configuration file:

management localhost 7505

This tells OpenVPN to listen on TCP port 7505 for management interface clients (port 7505 is an arbitrary choice – you can use any free port).
