This prevents the servers being accessed by un-related people.

In this case, you can simply run VNN on that PC and access it remotely by using that VNN IP.

2. For servers that not running on a Windows PC:

In this case, you need to use a Windows PC running VNN and then create a service from that PC to map a port from that PC to the PC running the server.

The picture below shows the way to map a port 12345 of VNN IP to port 80 of IP (Assume the server runs on the PC with IP of
