The Ubiquiti Cloud Gateway Ultra is a compact wired UniFi gateway for homes and small offices that need centralized management for 30+ UniFi devices and 300+ clients, with 1 Gbps IDS/IPS routing, firewall controls, and multi-WAN failover or load balancing.
Recommended For
- Home or small-office UniFi users with internet service up to 1 Gbps who want the gateway and UniFi Network controller in one device, rather than running a separate controller.
- People building a UniFi network with separate access points and switches who want one place to manage network devices, client settings, and gateway security.
- Households or small offices that want UniFi firewall and intrusion detection features, VLAN-based network separation, and VPN options without assembling a separate router-and-controller setup.
- Users who need a wired gateway with dual-WAN failover or load balancing, and whose internet and wired-device speeds fit within its 1 Gbps routing and 1 GbE LAN-port limits.
Real-World Use Scenarios
- For a home or small office building around UniFi access points and switches, the UCG-Ultra can replace a separate router and controller; network settings and adopted devices are managed from one UniFi interface.
- When a household wants to separate smart-home devices, guest Wi-Fi, and personal computers, the UCG-Ultra can route separate VLANs and apply network rules; UniFi switches and access points help carry those segments to wired and wireless devices.
- For a home worker or small office that needs a fallback when its main internet service drops, a second WAN can be configured for failover; the gateway switches traffic to the backup connection when the primary link is unavailable.
- When traveling, a user who needs to reach a home NAS or other local devices can use Teleport or another supported VPN option to connect back to the home network without exposing each device directly to the internet.
- For a home lab or small office replacing a basic ISP router, the UCG-Ultra can provide firewall inspection and traffic visibility while managing the UniFi network; actual throughput may vary with the ISP connection type and configuration.
