I think if you have access to your firewall, you can setup IP forwarding on 
it. For example you can set to forward incoming connection from 6000 port on 
the firewall to your <internal computer IP>:5900

After that when you connects with the vncviewer to <Firewall IP>:6000 form 
outside, firewall will forward your connection to <internal computer 

Hope, this helps.

Yours, Rick.
