Ubiquiti UXG-Lite UniFi Gateway 1GbE Firewall

UniFi Next-Gen Gateway Lite

The Ubiquiti UXG-Lite Gateway functions as a compact, high-performance security router designed for modern professional network environments. It replaces the legacy UniFi Security Gateway (USG) by providing a significant increase in routing capacity and security feature throughput. This device operates as a dedicated security gateway within a UniFi ecosystem. It requires an external controller such as a Cloud Key, a self-hosted UniFi Network application instance, or a Cloud Console. The hardware serves as the primary barrier between the internet and the internal network, managing traffic flow with precision.

The internal architecture features a dual-core ARM Cortex-A53 processor and 1 GB of DDR4 memory. This hardware configuration allows the unit to maintain gigabit line-rate routing while executing complex security tasks. Unlike previous entry-level models, this unit supports integrated threat management without severely bottlenecking local network speeds. The device utilizes a single 1 GbE RJ45 WAN port and a single 1 GbE RJ45 LAN port to facilitate traffic flow between the external ISP and the internal switch fabric.

Security remains a primary focus for this hardware. The system implements deep packet inspection (DPI) to categorize and monitor traffic across the network. It supports intrusion detection and prevention systems (IDS/IPS) to mitigate potential threats in real-time. These features operate at specialized throughput levels optimized for small-scale deployments or remote office locations. Administrators manage these security profiles through the centralized UniFi interface. This allows for granular control over firewall rules, port forwarding, and traffic shaping policies.

The physical design emphasizes space efficiency and thermal management. Measuring less than 10 centimeters on its longest side, the chassis fits into tight enclosures or sits discreetly on a desk. It receives power through a standard USB-C interface. The lack of an integrated access point or internal controller software allows the CPU to dedicate its entire resource pool to packet processing and firewall operations. This separation of duties ensures high uptime and consistent latency for critical business applications. Deployment involves a straightforward adoption process through the UniFi Network application version 8.0.7 or later.
