Installating NT4 RAS as VPN-Dialin to a Network

In this example, I use a Windows NT4 workstation as VPN-dialin to a Novell Netware network. Therefore, this page is using IPX as protocol, which makes this page slightly different from the RAS-installation described for NT4 Server.



Again, I did reload the Service pack 3 after each reconfiguration

(Service pack 3 was required due to another software package on my system)


I am starting with a Windows NT workstation configured for:

As Protocol, I need:
- IPX for connection to the Novell-server
- TCP/IP for the connection to the Internet
In addition to the regular Services,
I use the "Client Services for Netware"
for connection to Novell Netware servers.
Remote Access Service is now loaded
as additional service.
We need to check our Bindings:
(it is a long listed pasted together)
Since we do NOT want any access from
the Internet to our System, we deactivate
all Bindings with TCP/IP to our Network
adapter and to the Server and Workstation
modules
.
For proper connection to the Novell Netware
server, we MUST have valid bindings for
the IPX protocol.

As for the Server RAS installation, we create a connection to the Internet and test it before continuing to install VPN.


We continue with the installation of VPN-dialin:
(again very similar to the
procedure for NT4 server):

Under protocols, we install the VPN
"Point to Point Tunneling Protocol (PPTP)"You will be prompted for the number
of VPN-adapters:
on Windows NT4 Workstation, ONLY ONE
dialin is allowed, so select : 1

Under Services, configure RAS:
First, ADD the VPN1 adapter to the list of
RAS devices, then configure the VPN1 port:
In this example ("receive calls only") to
allow only incoming connections
(again, NT4 workstation will ONLY allow
ONE incoming connection. If you try
to configure more, it will advise you
to change to NT4 SERVER, which can
handle up to 255 incoming connections)






Then, configure the Network options for
RAS, since we have now to define the
RAS Server settings:


In this example, incoming connections are ONLY allowed to use IPX-protocol,
which is configured to allow clients access to the Entire network
(to allow access to the Novell Netware server).
This selecting will cause the message:

and you need to confirm with "YES". This will install:

RIP for NWLink IPX
which will handle the redirection of the
IPX-protocol between the VPN-connection
and your LAN connection
We need to check the Bindings:
RAS needs a binding to IPX.


I do NOT know, why it does NOT show
under the binding tab the adapters,
which are allowed to use IPX.
That information is available under
the tab: Protocols by looking under the
properties of the IPX-protocol:
here is lists the binding to both the
Ethernet board and to RAS.

That's it.
Make sure, that users have the
permission to dial-in (using User Manager):


Make sure, that you now get a connection to the Internet
(either a permanent
connection or via RAS-dialout, again very similar to
Allowing Connection to Windows NT4 RAS-VPN Server) and you can receive incoming VPN-calls,
which you can verify via the "Dialup Networking Monitor":
