I used this "enabler" app to set up a VPN Server on Mac OS X Mavericks before I went to China, so I can access Facebook, etc, from my iPhone and MacBook Air, while I was on WIFI networks in Chengdu, Sichuan. The iPhone or MacBook Air connects back to the VPN Server, which I'll show how on the latter part of this page, and all interaction with the Internet from that point on goes through the local private network, on an encrypted channel, totally bypassing proxies and filters that may have been set up on public networks to deny access to sites like Twitter and Facebook.
As far as I can test myself, this VPN Server works well (wonderfully, if I may add :)
There is an VPN Server built into every plain Mac OS X machine, only it's not activated unless you know how to type in a lot of geeky commands and dive into a lot of configuration files. What VPN Enabler does is to do all that stuff for you in just three (OK, maybe four) steps and just one click.
What is new in this release:
VPN Enabler can now save a signed mobileconfig profile, if the server it is running on has an SSL cert for the domain. It can also save the account password into the profile, if the profile is created while the user account is being newly created or having its password reset.
