How to connect OS X Yosemite to a Windows based SSTP VPN? I am trying to connect to a Windows based SSTP VPN network. I am using OS X Yosemite, I was wondering if there is any solution that can allow me to connect to a SSTP based VPN. 

For the record, I have already tried using EasyVPN, iSSTP, iSSTP2. all of which failed to connect, and they all seem to be not supported anymore.
The sstp-client works for me. It is a command-line program. I installed it using the homebrew command:

brew install sstp-client
