System Requirements

Note: 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. See Getting VPN Service for details.

Tunnelblick comes as a ready-to-use application with all necessary binaries and drivers (including OpenVPN and tun/tap). No additional installation is necessary — just add your configuration and encryption information.
