I've been considering a similar problem.
The most secure way I have come up with is to use the port forwarding
features of SSH. In this way (as far as I know) you only need to allow
the ssh port though the firewall. Note that I have not tested this at
all and I could be misunderstanding the SSH docs.
For example you could set it up so that when you connect to
localhost:5900 from your computer it goes though the ssh tunnel to the
sshserver:5900 which then forwards the request to workstation1:5900. A
bit of ASCII ard required
VNC Viewer
localhost:5900

Using something like this you would be able to map a local:remote port
combination for every vnc server. At least in theory. Take a look at:-
