VPN Activator 0.4Free
The free application is a GUI for the hidden VPN server in Mac OSX client OS.
The application will configure and start/stop the L2TP &PPTP VPN server hiding in your Mac.
All files necessary to do this are already part of the OS… so no Apple files are needed nor distributed by this application.
This application is not intended for large scale enterprise use. It is rather intended for common folks that wish to establish a VPN connection to their home network via their personal Mac.
