Some time ago I asked about VNC through a firewall that only allows port 80
to pass through. The following articles were suggested:

They imply that if you change the registry for "PortNumber" to a -5720
(5800-5720=80), you can talk through a firewall that only allows port 80.
This only seems to change the port number that the authentication uses (the
initial contact to the VNC host from the VNC client via web browser). My
understanding is that once the authentication completes, that VNC then
switches to 5900 for the rest of the connection (It may be called RFB). Is
this correct? If so, how do you get the rest of the connection that
switches to 5900 to be on port 80?
I was given the following number to represent -5720 (which you can't enter
in the registry), as a two's complement representation of -5720: 4294961576
Can anyone verify that this is correct and has anyone successfully switched
vnc to port 80 for use through a firewall?
Regards,
Steve
