Which port range must be open for Tableau Server License Service?

The correct choice for the port range that must be open for the Tableau Server License Service is 27000-27009. This specific port range is designated for the Tableau Services Manager (TSM) and Tableau Server license management. The License Service uses this range to facilitate communication and ensure that all components of the Tableau Server can validate their licenses appropriately.

The range spanning from 27000 to 27009 allows for multiple instances of the License Manager to run in conjunction, providing flexibility and reliability in licensing across different environments. This is crucial for organizations that may need to support multiple Tableau deployments or have a larger user base requiring concurrent access to Tableau Server functionalities.

Understanding the significance of this port range is essential for ensuring that Tableau Server operates smoothly, as any issues with licensing due to closed ports can prevent the server from functioning correctly or accessing necessary licenses.
