Multiple hop VNC?

Another option for Windows to just redirect a port would be 's portmapper.

Install it on the server
Then forward port 5901 on the server to a machine 5900. Then if you have
many machines you could forward port 5902 to machine b 5900.

It is free software. Now there is no encryption, so ssh would still be
the best. But you could allow only certain IP's.

One way (that also gets you encryption over the Internet leg) is to look
into SSH tunneling.  You would install the SSH server on the machine
can be accessed directly and have SSH forward the ports to the internal
machines.  Check out "More advanced use" on the VNC/SSH page:

It appears this is also possible with Zebedee.

Another option (that doesn't get you encryption) is VNCProxy:
