I am trying to set up a TightVNC connection between my fathers computer and mine over the internet. We both have broadband connections through routers. The TightVNC program apparently listens for connections via ports 5800 and 5900 and in a nother mode, through ports 5500. There fore I have port forwarded these on each router. However it is still not working.
Is there a way to do a ping test to these specific ports to see if the routher is letting it through to the lan side IP? A normal ping test fails.
