I'm going to be setting up a network at a data center and I was wondering if it's possible to have Windows Server 2008 R2 act as a VPN server.
Also, I've heard there are 3 main types of VPN: PPTP, L2TP/IPSec and SSTP. After some investigation it looks like to allow native (OS level) support for Mac OS X, Linux and Windows I would use PPTP or L2TP/IPSec. I also read that L2TP is more secure than PPTP, is this true?
Lastly, is it a good idea to install the VPN server on the primary domain controller (PDC), if not, why?
