UniFi - Ports Used

This article shows what UDP and TCP ports are used by the UniFi Network application by default. The information applies to both Network applications hosted on UniFi OS Consoles, such as UniFi Cloud Key (UCK-G2, UCK-G2-PLUS, and UC-CK) or UniFi Dream Machine (UDM or UDM-Pro), as well as self-hosted Network applications. 

For more information on how to change the default ports, see UniFi - Advanced: Changing Default Ports.

Note: Make sure to always update your Network application to the latest version.
