In this video, I am diving into UniFi’s High Availability (HA) Firewall setup—known as Sharrow Mode. As of Febuary 2025 it’s supported for the Dream Machine Pro, Dream Machine Special Edition, Dream Machine Pro Max, and the Enterprise Fortress Gateway. Whether you’re running a business network or building a robust homelab, this guide covers everything you need to configure HA and to maximize your network uptime.
