Installation of the Windows NT4 RAS-VPN Server

Back in the Network applet, we add now the PPTP as additional protocol:

You will be prompted for the number of simulatneous VPN-connections
to be allowed (please remember: while NT Server can handle up to 256 RAS
connections, Windows NT4 Workstation allows only ONE incoming RAS connection):

NT Setup will then bring to the RAS SEtup/Configuration:

Enter now via the Add-button the all available VPN - RASPPTPM devices:

Configure now each VPN-adapter on the VPN-server to allow a dialin
connection: to receive calls
(Windows NT 4 workstation will only allow you to configure 1 dialin connection!)

Configure the Network protocol for the Server Settings (for the incoming calls):

In my case and this example, I allow ONLY NetBEUI as protocol for
incoming connections (making it IMPOSSIBLE for break-In ("Hacker-attack")
via the Internet, which has to use TCP/IP)
Since we have now an additional protocol :

and additional network adapters (the VPN-adapters), we need to check
our bindings:

make sure, that TCP/IP is ONLY bound to the Modem- Adapter
(which is [5] Remote Access WAN Wrapper, see: RAS Installation for that)
while the VPN-adapters ( [6] and [7] Remote Access WAN Wrapper) have only
a binding with the local network protocol NetBEUI.

We are ready to allow incoming calls:
