Hi,

I'm looking for a solution on how to setup our corporate VPN.

For now, we have a Windows NT4-Domain secured by Checkpoint Firewall-1
running on NT4 server.

For some employees we'd like to setup a VPN. All employees use either NT4
Workstation or Windows 98. Then they connect to the VPN they should act as a
domain-member.

On the firewall I was thinking about forwarding one port to a Linux NAT box
that accepts SSH-connections (so all connections are secured by SSH). As an
experiment we've tried connection from our LAN over SSH to another
(external) Linux box by using the ppp-daemon. This gave no problem at all.
Problem is that we would like to have the possibility to initiate a
connection from the outside to the Linux NAT server and the connecting side
should only be running NT4 WS or Win98. Anybody who's got some clues where I
can look for possible solutions?

Regards,

Koen
