I'm currently renting a virtual server running Windows Server 2008 R2 which I'm trying to set it up as a VPN server but can't figure out how to do it. I tried doing it the simple way; adding an incoming connection in network connections. Unfortunately, the server only has one network adapter which has a remote IP address, so clients are unable to connect because there are no IP addresses available on the same subnet as the server. When manually setting the available range of IP addresses to an internal IP, I can connect to the server but then there is no internet access.
I then followed this guide http://www.windowsecurity.com/articles/Configuring-Windows-Server-2008-Remote-Access-SSL-VPN-Server-Part2.html
, but when I got to figure 15 I couldn't follow any longer because the option for VPN and NAT requires 2 network adapters. I instead selected custom configuration and then VPN and NAT, but this leads to different configuration. I've never been one for managing networking so at this stage I was completely lost.
If anyone could point me in the right direction it would be very much appreciated.
