ArcGIS GeoEvent Server uses certain ports to communicate with machines on the Internet and intranet. Below is a description of the ports that you may need to allow on your firewall.
HTTP port 6180
GeoEvent Server communicates through port 6180, and you must ensure that your firewall allows HTTP communication through this port. This port is used by GeoEvent Server REST endpoints.
HTTPS port 6143
When HTTPS is enabled, GeoEvent Server uses port 6143 by default. This port is used by GeoEvent Manager and GeoEvent Server administrator REST endpoints.
Ports 9220 and 9320
The spatiotemporal big data store, available with ArcGIS Data Store, communicates through ports 9220 (HTTP) and 9320 (TCP). If you writing data to the spatiotemporal big data store using GeoEvent Server you will need to open these ports.
Internally used ports (5565, 5575, 27271, 27272, and 27273)
Port 5565 is the default port used by the GeoEvent Server Receive Text from a TCP Socket Input Connector. This port will need to be opened if you are using this connector with the default port setting.
Port 5575 is the default port used by the GeoEvent Server Push Text to an External TCP Socket Output Connector. This port will need to be opened if you are using this connector with the default port setting.
Ports 27271, 27272, and 27273 are ports necessary for GeoEvent Server, specifically RabbitMQ.
Other ports
GeoEvent Server uses the ZooKeeper platform service hosted by ArcGIS Server. See Ports used by ArcGIS Server for information on the ports necessary to open when using GeoEvent Server, specifically ports 2181, 2182, and 2190.
