WinVNC server connecting automatically to clients over WAN

I may be misinterpreting what you said, but it appears you're saying
that the VNC client connections drop as soon as you stop the VNC
service.  That's expected; they are no longer connected to anything.

Does NetxXray show you the connected ports?

If not, you can go to the server and issue this command in a console
prompt:

netstat -an

this will show you all connections in numeric form.  You should see on
the lefthand side the server address listing and ports; for example, if
the server address is 192.168.1.1 you will see lines like

UDP 192.168.1.1:139 yadda-yadda
TCP 192.168.1.1:5900 yadda

Connections to port 59xx on the server  are from *live* VNC connections.
If you have connections on port 139, those are Windows clients actually
accessing fileshares over the network.  See if you are showing clients
on port 139.

I saw
