The simplest way is to forward the connection rather than trying to "proxy" it.  The primary benefit of proxying the connection is to allow an additional level of security given that VNC is seen as insecure.

Check out : http://www.linuxquestions.org/questions/linux-networking-3/forward-port-port-80-to-lan-web-server-31132/ for information about forwarding the connection from "outside" to "inside".  You will need to know the destination port.

I'm not sure where you received your info.  The primary benefit of the VNC Proxy is so you don't have to have a static ip address on every single client computer that you want to connect to.  A workstation that has the UltraVNC Server installed can be connected to simply by knowing it's DNS name.  Additionally, you only have to forward one port to access all those client machines rather than a separate port for every single one of them.

As for VNC being insecure, I'd say that's a matter of opinion, especially as UVNC can utilize MS-II domain login protocol and RC4 encryption.  If it is insecure using that method, I guess the blame would be on the insecurity of ActiveDirectory logins.
