UniFi Network - Required Ports Reference

The following lists the UDP and TCP ports used by UniFi. This information mainly applies to users with a self-hosted UniFi Network Server, or users with third-party devices and firewalls. For this reason, we generally recommend a full UniFi deployment for seamless deployment and optimal native compatibility.

Local Ingress Ports (Incoming)

Protocol Port Number Usage
TCP/UDP 53 Used for DNS. This is required for Guest Portal redirection, downloading updates, and remote access.
UDP 3478 Used for STUN.
UDP 5514 Used for remote syslog capture.
TCP 8080 Used for device and application communication.
TCP 443 Used for application GUI/API as seen in a web browser. Applications running on a UniFi Console
TCP 8443 Used for application GUI/API as seen in a web browser. Applications running on a Windows/macOS/Linux machine
TCP 8880 Used for HTTP portal redirection.
TCP 8843 Used for HTTPS portal redirection.
TCP 6789 Used for UniFi mobile speed test.
TCP 27117 Used for local-bound database communication.
UDP 5656-5699 Used by AP-EDU broadcasting.
UDP 10001 Used for device discovery.
UDP 1900 Used to "Make application discoverable on L2 network" in the UniFi Network settings.
UDP 123 Used for NTP (date and time). Required for establishing secure communication with remote access servers.

Note: Although TCP 22 is not one of the ports UniFi Network operates on by default, it is worth mentioning that is the port used when UniFi devices or the Network application is accessed via SSH.

Ingress Ports Required for L3 Management Over the Internet (Incoming)

These ports need to be open at the gateway/firewall as well as on the machine running the UniFi Network application. This would be achieved by creating port forwards on the gateway/firewall where the application is running.

Protocol Port Number Usage
UDP 3478 Used for STUN.
TCP 8080 Used for device and application communication.
TCP 443 Used for application GUI/API as seen in a web browser. Applications running on an UniFi Console
TCP 8443 Used for application GUI/API as seen in a web browser. Applications running on Windows/macOS/Linux machines
TCP 6789 Used for UniFi mobile speed test.
TCP 8880 Used for HTTP portal redirection. (only needed if using Guest hotspot)
TCP 8843 Used for HTTPS portal redirection. (only needed if using Guest hotspot)

Egress Ports Required for UniFi Remote Access (Exiting)

In most cases, these ports will be open and unrestricted by default.

Protocol Port Number Usage
TCP/UPD 53 Used for DNS This is required for Guest Portal redirection, downloading updates, and remote access.
UDP 3478 Used for STUN.
TCP/UDP 443 Used for Remote Access service.
TCP 8883 Used for Remote Access service.
UDP 123 Used for NTP (date and time). Required for establishing secure communication with remote access servers.

Changing Default Ports

Changing default port assignments can only be done on self-hosted UniFi Network Servers (Windows/macOS/Linux). This can be accomplished as follows:

  • Close any instances of the UniFi Network application.
  • Modify the system.properties file, which can be found in the directory <unifi_base>/data/system.properties. For example, if port 8081 was in use and port 8089 was open, you could change it by modifying unifi.shutdown.port=8081 to unifi.shutdown.port=8089
  • Restart the UniFi Network application.

Note: Make sure there are no leading or trailing spaces, comments, or other characters (i.e., #) on any custom lines. Otherwise, UniFi Network will ignore the customizations.
