The following includes the UDP and TCP ports used by UniFi. This information mainly applies to users with a self-hosted UniFi Network Application, or users with additional third party devices and firewalls. For this reason, we generally recommend a full UniFi deployment for seamless deployment and optimal native compatibility.
- Local Ingress (Incoming) Ports
- Ingress (Incoming) Ports required for L3 management over the internet
- Egress (Exiting) Ports required for UniFi Remote Access
- Changing Default Ports
Local Ingress (Incoming) Ports
|
Protocol |
Port number |
Usage |
| TCP/UDP | 53 | Port used for DNS. This is required for Guest Portal redirection, downloading updates, and remote access. |
| UDP | 3478 | Port used for STUN. |
| UDP | 5514 | Port used for remote syslog capture. |
| TCP | 8080 | Port used for device and application communication. |
| TCP | 443 |
Port used for application GUI/API as seen in a web browser. Applications hosted on a UniFi OS Console |
| TCP | 8443 |
Port used for application GUI/API as seen in a web browser. Applications hosted on Windows/macOS/Linux |
| TCP | 8880 | Port used for HTTP portal redirection. |
| TCP | 8843 | Port used for HTTPS portal redirection. |
| TCP | 6789 | Port used for UniFi mobile speed test. |
| TCP | 27117 | Port used for local-bound database communication. |
| UDP | 5656-5699 | Ports used by AP-EDU broadcasting. |
| UDP | 10001 | Port used for device discovery. |
| UDP | 1900 | Port used for "Make application discoverable on L2 network" in the UniFi Network settings. |
| UDP | 123 | Port used for NTP (date/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 in this article since it is the port used when UniFi devices or the Network application is accessed via SSH.
Ingress (Incoming) Ports required for L3 management over the internet
Note: These ports need to be open at the gateway/firewall as well as on the UniFi Network application host. This would be achieved by creating port forwards on the gateway/firewall where the application is hosted.

Egress (Exiting) Ports required for UniFi Remote Access
Note: In most cases, these ports will be open and unrestricted by default.

| TCP/UDP | 53 | Port used for DNS. This is required for Guest Portal redirection, downloading updates, and remote access. |
| UDP | 3478 | Port used for STUN. |
| TCP/UDP | 443 | Port used for Remote Access service. |
| TCP | 8883 | Port used for Remote Access service. |
| UDP | 123 | Port used for NTP (date/time). Required for establishing secure communication with remote access servers. |
Changing Default Ports
Changing default port assignments can only be done on self-hosted Network applications (Windows/macOS/Linux). This can be accomplished as follows:
1. Close any instances of the UniFi Network application.
2. 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=8081tounifi.shutdown.port=8089
3. Restart the UniFi Network application.
Note: Make sure there are no leading or trailing spaces, comments, or other characters like hash tags (#) on any custom lines. Otherwise, UniFi Network will ignore the customizations.
