Port Usage for Bare-Metal NIOS-X Servers

When deploying a bare-metal NIOS-X server, you must open applicable ports on the server to ensure that all services are functioning properly.

The following table lists the ports that need to be available on the bare-metal NIOS-X server, in addition to the port usage for firewalls, as described in NIOS-X Server Connectivity and Service Requirements.

IP Protocol	Port	Services using this port	Description

IP Protocol	Port	Services using this port	Description
TCP	22	Data Connector NIOS	Required for incoming SCP data transfer from NIOS to Data Connector when deployed as a container. When you deploy Data Connector as a container, ensure that there are no SSH processes listening on port 22. You must terminate these SSH processes for Data Connector to collect data from NIOS.
TCP	53	NIOS-X servers	Ensure that there are no other processes using port 53 on the server system on which your server will be deployed. For example, some Ubuntu systems running local DNS cache (system-resolved) might occupy port 53, and your server might not function properly in this case.
TCP	514	Data Connector	Required for Data Connector secure syslog for RPZ hits data. If you deploy Data Connector as a container, ensure that this port is not used by other processes.
TCP	2222	NIOS-X servers	Used by an internal service for remote monitoring.
TCP	6514	NIOS (SCP data transfer) Data Connector	Used for transferring syslog data from NIOS to Data container. Port 6514 is a default secure port. If you deploy Data Connector as a container, ensure that this port is not used by other processes.
TCP	8125	Data Connector	This is an internal port used for communications between containers. If you deploy Data Connector as a container, ensure that this port is not used by other processes.
TCP	8126	Data Connector	This is an internal port used for communications between containers. If you deploy Data Connector as a container, ensure that this port is not used by other processes.
TCP	50514	Data Connector	This is an internal port used for communications between containers. If you deploy Data Connector as a container, ensure that this port is not used by other processes.
