Orchestrator uses specific ports to communicate with the other systems. The ports are set with a default value that cannot be changed.

Default Configuration Ports

To provide the Orchestrator service, you must set default ports and configure your firewall to allow incoming TCP connections.

Note:

Other ports might be required if you are using custom plug-ins.
