Securing communication ports
To ensure secure transmission of network traffic to and from the Cloud Pak for Data cluster, you need to configure the communication ports used by the network.
Cluster ports
Ports for services
When you provision a new service or integration on your Cloud Pak for Data cluster, the services might require connections to be made from outside the cluster. For example, you might require connections when you access databases or virtualize data through an ODBC/JDBC connection. If the service or integration requires connections to be made to the cluster, locate the port numbers from each service's Details page and open those network ports. Each port is TCP, and randomly allocated between the 30000-32767 range.
Some services implement network policies so that only the ports that are needed by the services are opened. You might need to verify which ports are available. For more information, see Additional network policies implemented by individual services.
