I am getting this error when I try to connect to my remote PC. Which is a windows Vista machine running TightVNC server on port 5900.

Here are some outputs:

From the last traceroute result !X I think means timeout? That makes me think it could be a firewall, but I have added an exception to the windows firewall during installation. What could be the problem?

Is there a router in between the vista machine and it's internet connection? You will need to NAT port 5900 from the outside to the address of the vista machine. Because of these kinds of challenges, many use GoToMyPC or Teamviewer or another remote access software because they send their information over ports that are generally allowed by the router.

Of course that must be it! Thanks for your tips! – Robse Mar 7 '12 at 14:30
