I wanted to setup a UniFi USG (Ubiquiti Unifi Security Gateway) with round robin multi-WAN and incoming port forwarding on both WAN connections.
Quite a few links were the result:
- [WayBack] USG (not Pro) can you run dual WAN | Ubiquiti Community:
- You will need controller 5.5x and its bundled firmware to have the (Ex VoiP) WAN2 or LAN2 possibility.
- You can set 2 modes with the dual WAN configuration. You have the option to use them in a failover configuration or in weighted load balanced configuration. Weighted load balancing allows you to specify a percentage of traffic to go over the second link.
- [WayBack] Ubiquiti USG UniFi Firewall dual wan – Google Search
- [WayBack] install Ubiquiti USG UniFi Firewall multi-wan – Google Search
- [WayBack] UniFi – USG Port Forward: Port Forwarding Configuration and Troubleshooting – Ubiquiti Networks Support and Help Center
- [WayBack] install Ubiquiti USG UniFi Firewall – Google Search
Adoption was another headache. Some links on that too:
- [WayBack] UniFi – Troubleshooting Device Adoption Failures – Ubiquiti Networks Support and Help Center
- [WayBack] UniFi – Device Adoption Methods for Remote UniFi Controllers – Ubiquiti Networks Support and Help Center
- [WayBack] USG won’t adopt, tried manual upgrade of firmware | Ubiquiti Community
- [WayBack] Newbie stuck – USG set up and upgrade | Ubiquiti Community

- [WayBack] Can’t adopt, provision, or upgrade firmware on any devices with new controller install | Ubiquiti Community

If you end up in a cannot adopt state, then a reset is the only practical way to go:
