There are numerous uses for a VPN (Virtual Private Network) connection, but by far the most popular is for gaining remote access to computers. For anyone who works with computers in more than on location this can be a lifesaver, and one of the most popular free VPN tools is OpenVPN.
While OpenVPN is a powerful tool that boasts many advanced features such as load balancing, access controls and SSL based security, many users have also found that it can be difficult to configure.
This is where Tunnelblick comes into play, offering a graphical front end to this handy utility. The program can be used to control both OpenVPN servers and clients.
Tunnelblick does not necessarily make OpenVPN and instantly accessible, easy to use program for the masses, but it does help to make the life of anyone already managing a VPN connection a little easier.
