Hi ! A computer that is behind a firewall that blocks connection om port 5500, 5800 and 5900 is trying to connect to me. I have turned the Key "AutoPortSelect" to 0 and added the DWord "PortNumber" to my registry and set the value to 80 How can VNCViewer connect to VNCServers that is listening on port 80 ? Both computers run Windows2000 Jan-hekan Westbom MECAD
