IP Port Number Requirements
The install process prompts for two IP port numbers: the TCP lListener and HTTP listener. It also uses the next two consecutive ports after the supplied HTTP listener port for FDS use. This results in a total of four IP ports.
The supplied IP port numbers must be above the IANA registered well-known reserve range (numbers under 1024) and not over the maximum legal number (65535). Additionally, do not use IP port numbers already being used by other applications or products. Netstat, or netstat like commands, should reveal what actual ports are in use.
