You may need to open the following ports in your firewall to allow ArcGIS Data Store machines to communicate with each other and with other parts of the web GIS:
- 2443: ArcGIS Data Store communicates through this port.
- 9876: Relational data stores communicate through this port.
- 29080 (HTTP) and 29081 (HTTPS): Scene tile cache data stores communicates through these ports.
- 9220 (HTTP) and 9320 (TCP): Spatiotemporal big data stores communicate through these ports.
ArcGIS Data Store also uses port 9006 to internally communicate with Tomcat. You don't need to open this port in the firewall.
