Ports used by KUMA during installation

For the program to run correctly, you need to ensure that the KUMA components are able to interact with other components and programs over the network via the protocols and ports specified during the installation of the KUMA components.

Before installing the Core on the device, make sure that the following ports are free:

The table below shows the default network ports values. The installer automatically opens the ports during KUMA installation

Ports used by the OOTB predefined resources:

KUMA Core traffic in a fault-tolerant configuration

The "KUMA Core traffic in a fault-tolerant configuration" table shows the initiator of the connection (the source) and the destination. The port number on the initiator can be dynamic. Return traffic within the established connection must not be blocked.
