You could go and forward the interesting ports to the NT machine.
Your problem is that the privat IP's you are using are not routable on
the internet. If you are using a VPN which is tunneling your subnet
through the internet, you will only need to put some routing information
into the /etc/route.conf which points through the VPN device. The tunnel
will then take the data through the internet to the remote LAN.
Which VPN protocol are you using???
