Tunnelblick is a free, open source graphic user interface for OpenVPN on OS X. It provides easy control of OpenVPN client and/or server connections. It comes as a ready-to-use application with all necessary binaries and drivers (including OpenVPN, easy-rsa, and tun/tap drivers). No additional installation is necessary -- just add your configuration and encryption information.

To use Tunnelblick you need access to a VPN server -- your computer is one end of the tunnel and the VPN server is the other end. For more information, see Getting VPN Service.

Support is provided by the Tunnelblick Discussion Group.
