These days we are seeing a lot of topic oriented to the business world and we are now going to see something that may also interest us but free and simple as we can, although with some drawbacks.
Tunnelblick is nothing more than a fairly simple project that aims to help us with VPN connections in Mac OS X thanks to the use of a configuration file, and that is where it fails: we cannot pretend that an application is simple if we have to edit in text mode , you have to help more from the graphical interface.
In the end, the app is nothing more than a free alternative for moderately advanced users who are friends with editing configuration files.
