VNC Remote Viewing into LAN

Mon Jul 28 20:16:00 2003

Thanks for William Hooper's reply of Friday July 5.
I have set up port routing on my D-Link 614+ router as:
Port1: Private Port = 5800, Public Port = 5800
Port2: Private Port = 5900, Public Port = 5900
Both into which is where my VNC server sits.
I then used my dialed-in PC and Internet Explorer  with the address and got message "page cannot be displayed" (also
tried :5800 with same result)
Then used VNC Remote Viewer with address and got message
"Failed to connect to server"
Any further advice?
