This table lists the ports used for intra-system communication by the services. On every instance in the system, each of these ports:

  • Must be accessible from every other instance in the system.
  • Should not be accessible from outside the system.

You can find more information on how these ports are used in the documentation for the third-party software underlying each service.

Note: For a secure and recommended firewall setup using these internet ports, see Example HCI firewall setup.
