Maybe try the VNC Personal Edition using the One-Port HTTP & VNC feature?

You can email their support first to see if this will resolve the problem.

"One-Port HTTP & VNC
One-Port HTTP & VNC allows VNC Server to serve VNC Viewer for Java and VNC sessions through a single TCP port, simplifying NAT and firewall configuration."

I believe VNC uses Ports 590x (5900 for display 0, 5901 for display 1, etc.).

All you should need to do is forward port 5900 from your router to

You need to forward the port used by VNC to the VNC server computer.  Default port is 5900.  It would be wise to change this port though.

Once the port has been forwarded, use a VNCViewer program with as the hostname and that should be it.
