No problem, but please send responses to the list.

Private Port needs to be 5900
> Public Port - set to 5900

If you also want to use the java viewer, you will need to set up another
port forward using:
Private Port - 5800
Public Port - 5800
> Public IP Address of Router is 126.96.36.199
> and when I use VNC Viewer with 188.8.131.52:5900 (or 5800) I get null
Because you are trying to talk to the HTTP port (5800).

Because to use the Java viewer you need to forward *both* the HTTP port
(5800) and the RFB port (5900).
> When I tried VNC Viewer with this setup I still got null response.
> Would appreciate your further advice.

You can to some extent play around with what external port you want to
use, but the internal ports need to be the ones that VNC is listening on.
