Mac and Windows Server 2008-based SSTP VPN. Does it work?

Question

Does anyone know how to set up a Mac with a Windows Server 2008 SSTP VPN? Is it even supported? We have said VPN installed here, and I need to know if we can have Macs as well as Linux clients working with it.

Answer 1

Unfortunately, this doesn't seem to be possible.
Below are some sources for this information.

wikipedia: Secure Socket Tunneling Protocol

SSTP is only available in Windows since version Windows Vista SP1, and in RouterOS. It is fully integrated with the RRAS architecture in these operating systems, allowing its use with Winlogon or smart card authentication, remote access policies and the Windows VPN client.

SSTP is a great addition to the VPN toolkit to enable users to remotely and securely connect to the corporate network. But there is no solution for Linux, MAC OS and other OS, SSTP limited only for Windows users and seems it's a big problem.

The next two sources are from private VPN providers.

If you use a computer that installed Windows Vista or Windows 7, Congratulates you! you can use SSTP vpn on your computer. It's unfortunate that other operating system do not support SSTP vpn current.

Answer 2

There are two client implementations available for Linux: http://www.hsc.fr/ressources/outils/sstoper/index.html.en and http://sourceforge.net/projects/sstp-client

I am trying to use the first one at the moment. The VPN I am trying to connect to uses EAP with certificates, but pppd does not seem to support it. I am hoping that the EAP_TLS patch for pppd might help but no luck so far.
