NetWorker Processes and Ports
The rabbitmq process on the NetWorker server uses port 5671. The NetWorker processes use this port/service to relay information between each other and present them in the NetWorker user interfaces.
See operating system vendor instructions for creating firewall rules; The system/security administrator must make these changes. Once changes are applied to the operating system firewall, confirm if port 5672 connectivity succeeds between the NetWorker server and NMC server. If the connection still fails, ensure that a network firewall is not blocking the communication.
