HI,
CAD opens random port because the option WEBPORT has default value "0 0" and 
CAD randomly assign a free TCPport (the first parameter for CAD, the second for 
WEB client).
I think it’s impossible to prevent this.
As workaround you can set fixed port(s) and close it using firewall.
Example: WEBPORT 55000 0 or WEBPORT 55000 55001
