Tunnelblick

Tunnelblick is a free, open source graphic user interface for OpenVPN on Mac 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 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.

Tunnelblick uses Sourceforge to distribute binaries - Tunnelblick's main project page is at http://tunnelblick.net.
