Overview

UniFi Network Application 9.5.18 includes the improvements and bugfixes listed below.

 

Added Channel AI

Uses neighboring AP signals to optimize channel distribution. Designed for controlled, very high-density deployments where external interference is limited.

Provides a visual channel map for quick insights.Automated optimization ensures balanced channel usage.Requires AP firmware 8.2.14/6.7.31 or newer.

Added WiFi Multicast Filtering and VLAN Bridging

Enhances WiFi performance by allowing selective filtering of multicast services to reduce unnecessary airtime usage. Also introduces VLAN Bridging, enabling multicast proxying between VLANs for WiFi clients. VLAN Bridging is available only when the Gateway mDNS Proxy is disabled.

Requires UAP firmware 8.2.14 or newer.

 

Improved Port Manager

Port AI anomaly reporting – Gain deeper insights into port health with anomaly detection and scoring. In addition to live insights, Port AI now generates a 24-hour Anomaly Score across key categories:Cables & Power.Network Loops & Storm Control.Broadcasts & Discovery.Traffic Path Health.Enhanced Port Details – The side panel now provides richer visibility and context for each port, including:Port status at a glance.Activity logs for anomaly events and admin changes.MAC table displaying currently connected devices.We recommend using UniFi Switch firmware 7.2.123 or newer.

 

Added Default Security Posture Setting (Allow All / Block All)

Introduces a global default security posture with options to Allow All or Block All. Selecting Block All will isolate all newly created VLANs, Ethernet Port Profiles, and devices by default, while existing configurations remain unchanged.

Improvements

Added adoption instructions in the Dashboard for UniFi OS Servers.Added support for Auto IPv6 WAN Prefix Delegation Size.Added a banner to Apple TV devices to update their firmware when experiencing connectivity issues.Improved validation for Object-Oriented Networking.Improved the RADIUS Local User management user experience.Improved the NeXT AI Flows filtering user experience.Moved Profiles to Settings Overview.

Bugfixes

Fixed an issue where the Objects page could freeze in rare cases.Fixed an issue where the Port Forward overlap validation was incorrectly triggered.Fixed an issue where DS-Lite Auto & MAP-E didn’t work with Static and Single Network IPv6.Fixed an issue where deleting a client group or network used in Objects could introduce dead ends.Fixed an issue where Site-to-Site VPN configurations weren’t updated when the WAN DHCP IP changed.Fixed an issue where Dashboard WiFi Upload/Download data was shown incorrectly when using a single Radio.Fixed an issue where Firewall rules for NAT IPv6 were incorrectly generated in rare cases.Fixed an issue where SLA profile changes are not provisioned.Fixed an issue where Source NAT didn’t use the interface’s IPv6 address in Policies/NAT.Fixed an issue where some VLAN Settings were not removed when setting up MC-LAG.

UniFi Network Native Application for UniFi OS

A specific application version that is only compatible with the UDM, UDR, UDR7, Express, Express 7, UCG-Ultra, UCG-Max, and UCG-Fiber (running UniFi OS 3.1.6 or newer).

The UniFi OS update uses the application version required for your console.The manual update process via SSH requires you to use the compatible package. Incompatible packages will be rejected on installation.Older UniFi OS versions (before UniFi OS 3.1.6) on the UDM and UDR still use regular UniFi Network Application for UniFi OS.
