VPN Server on Windows 2008 Server

Question

VPN

Are there any ways to raise a W2k8 VPN without using AD, using workgroups? All the information that I googled in one way or another is tied to AD: or certificates, or authorization, or something else.
At the same time, there are the following difficulties: the server in the main office is behind NAT in the form of an ADSL modem, the second office generally clings through a WiMax dish.
The IPs of both offices are constant, and people from the second office can access the server via RDP, but the VPN connection does not go through.

Answer 1

Yes Easy. You raise the Routing and Remote Access service on the desired server, create users on this server and that's it.

Answer 2

"To connect to the network, users must have accounts on the remote access VPN server or in Active Directory® Domain Services"

why for VPN AD - allah knows
instead of google all sorts of nonsense - it is useful to read the documentation on the manufacturer's website

Answer 3

well, how would you use openvpn.net

Answer 4

AD VPN is not required. it can be both local users on the server, and what is screwed - ldap, hell.
I'm currently having a problem routing vpn users to local networks on a different subnet :(
