Firewall Throughput: Not published by Ubiquiti; no firewall-only rating on the official spec sheet
Threat Prevention Throughput: 1 Gbps (IDS/IPS, vendor rating); reviews report roughly 900-950 Mbps sustained, and lower on faster or PPPoE links
IPsec VPN Throughput: Not published by Ubiquiti; WireGuard about 300-600 Mbps in server mode (community-reported)
Max Sessions: Not published; spec sheet lists 300+ simultaneous users and 2,000 MAC address table entries
New Sessions/sec: Not published
Interfaces: 1x 2.5GbE RJ45 WAN (default, reassignable); 4x 1GbE RJ45 LAN; up to 4 WAN-capable ports for multi-WAN
Form Factor: Compact desktop, fanless, 141.8 x 127.6 x 30 mm, 520 g, 6.2 W max, USB-C 5V/3A power
Curation Review
✔ Pros:Built-in UniFi controller, so no separate Cloud Key needed; Low price for a gateway with IDS/IPS and controller included; Built-in IDS/IPS with no subscription fee; 2.5GbE WAN port for multi-gig internet; Multi-WAN failover or load balancing; Low power draw and fanless design; VPN (IPsec, OpenVPN, WireGuard) and VLANs without a subscription
✘ Cons:IDS/IPS ceiling of 1 Gbps limits secure throughput on links above about 1 Gbps; Real-world throughput drops further with PPPoE or threat detection enabled; No Wi-Fi radio, so separate access points are required; No PoE output and no UniFi Protect, Access, or Talk support; Only one 2.5GbE port; the other four are 1GbE; Runs warm and should not be stacked on heat-generating equipment; Firewall and VPN throughput figures are not published by Ubiquiti, so buyers must rely on third-party tests
IPsec VPN Throughput: Not published by Ubiquiti; WireGuard/Site-Magic VPN up to 500 Mbps (third-party review, untested method)
Max Sessions: Not published
New Sessions/sec: Not published
Interfaces: 5x 2.5GbE RJ45 (1 WAN + 4 LAN, one LAN port can be remapped to a second WAN)
Form Factor: Compact desktop, 142 x 127 x 30 mm, USB-C 5V/5A power (max 16.1 W)
Curation Review
✔ Pros:2.5GbE WAN and LAN ports on a compact, low-power chassis (max 16.1 W); 512GB built-in NVMe storage on the standard SKU for local UniFi data; Integrated UniFi controller with IDS/IPS and no license or subscription fees; Supports 300+ clients and 30+ UniFi devices; Multi-WAN capable through the remappable LAN port
✘ Cons:Only 1.5 Gbps with IDS/IPS enabled, well below the 2.5 Gbps routing figure; IPsec VPN throughput, session counts and new sessions per second are not published; No PoE output and no built-in Wi-Fi access point; No LAG/LACP support; 500 Mbps VPN throughput is limiting for high-volume site-to-site tunnels
