Unifi Cloud Gateway WAN2 Failover Setup

Here is a complete, step-by-step guide for setting up a dual-WAN failover on a UniFi Cloud Gateway (UCG) Max or Ultra network controller!

UniFi Console Migration Guide:

Dream Machine Upgrade or Migration: Including Cloud Account Claiming, Cellular WAN Failover, SSH Credential Capture & Orphaned Device Recovery

This guide covers migrating all adopted UniFi devices (APs, switches, cameras) from a Dream Machine (UDM) to a Dream Machine Pro (UDM-Pro) with minimal disruption. It assumes you are replacing the UDM entirely and the UDM-Pro will take the same network role.

This guide has been updated with real-world field experience from an actual UDM → UDM-Pro migration, including the cloud account claiming procedure, Mesh AP tweaks required post-restore, and cellular WAN failover configuration using a designated LAN port as WAN3.

Network Rack Upgrade

After 2 months of careful planning, part sourcing, and even some 3D printing magic, my freshly upgraded network rack is finally live! From a robust Tecmojo 12U frame to a lineup of SBCs and mini-PCs, every component has been placed with purpose. In this post, I’ll walk you through the hardware, share product links, and highlight the key modules that bring my homelab, and the Pacific Northwest Computers’ infrastructure, to life!!
