Frequently Asked Questions

Do I need the UniFi Controller to use the USG?

Yes for full configuration. The UniFi Controller software is bundled at no extra charge and handles device discovery, provisioning, and ongoing management of the USG and other UniFi devices from one interface.

How many ports does the Unifi Security Gateway have?

Three 10/100/1000Base-T gigabit ethernet ports plus a dedicated management port. Typically one port is WAN, one is LAN, and the third is configurable for a second WAN or a separate LAN segment.

Can the USG handle VLANs and guest network separation?

Yes. The USG creates virtual network segments with VLAN support, so you can separate guest, IoT, and trusted traffic and apply distinct firewall policies to each.

Does it support VPN access for remote workers?

It includes a VPN server for secure communications, letting remote users connect to internal network resources over an encrypted tunnel.

Is the USG good for VoIP phone systems?

It offers QoS designed for enterprise VoIP, which prioritizes voice packets so calls stay stable when other traffic saturates the connection.
