Multiple access ports on nodes hosting the Hybrid Data Pipeline server must be opened and unassigned to other functions. The following tables document the required ports and default port numbers. The installation program for the Hybrid Data Pipeline server confirms that default ports are available and allows new port values to be assigned when needed. Port values are passed during the installation of Hybrid Data Pipeline servers.

A Server Access Port must be opened for the load balancer. As a matter of best practices, the load balancer should be configured for SSL/TLS termination.

The Shutdown Port must be opened. However, as a matter of best practice, the Shutdown Port should not be available outside the firewall of the Hybrid Data Pipeline server. For a load balancer installation, the Internal API Port on any node must be open to all the other nodes in the cluster. The Internal API Port should not be available outside the firewall.

The Message Queue Port must be opened. For a load balancer installation with the On-Premises Connector, the On-Premises Access Port and the TCP Notification Server Port must be opened for the load balancer.
