Virtual Private Network in Linux

I need to set something up in Linux, but I'm not sure how to do it.

I run an operating system (non Linux) as a guest under Linux. That guest
can be accessed anywhere in my private network - over my LAN via TCP/IP.
For example - the operating system can be connected to via tcp/ip address
192.168.0.10 . The guest doesn't use ports - but has it's own network
protocol. You connect to it via an emulator designed for the OS - you
supply the emulator an IP address - in this case 192.168.0.10 - and you
connect.

I would like to access the guest operating system outside of my network -
over the internet.

Lets say my ip address on the internet is 63.65.100.72 . What I need to do
is to be able to access my guest at 63.65.100.72 - that request would be
routed to 192.168.0.10 . I think of it as accessing a virtual private
network. The IP address I would supply my emulator would be 63.65.100.72
and somehow internally this would be forwarded or routed to the ip address
192.168.0.10 .

Is there a way to do this with Linux? Is there a software component I can
install to achieve this task?

Thanks ,

Bob

If you set up a VPN to your network, then all addresses on that network
should be available. I do that here. If you want to connect only to that
one system, you can set up your firewall, to pass the connection to that
system, provided suitable software is available. A good choice for VPN is
OpenVPN. It has both Linux & Windows clients.
