Firewalla Gold and Unifi Router (Dream Machine Pro) / Switch
I am seeing this weird problem when I upgrade my network equipment at home from EdgeRouter/EdgeSwitch to the newer Unifi router/switch. Ubiquiti has this weird way to "adopt" all the equipment to their application before you can fully configure them. However when I connect four of my ports from Firewalla Gold to the four ports on Dream Machine Pro each is assigned with a different VLAN, it somehow gets the way how the machine can adopt other switches. So all my switches essentially just get stuck in an "adoption loop" non-stop. It took me almost 10 hours after I found turning off Firewalla will just fix the problem. This problem only affect switches but not AP. I am using 1 L3 and 1 L2 switch
I am looking for a suggestion what exactly is happening here? If the somehow there is a conflict in the port can I simply fix it by moving the port to different one?

I found that new new router/switches are automatically added to the quarantine group, which there seems to be a default rule to block all internal-only traffic.
The way these equipment are integrated into a centrally control panel is by having all the "adoption" through communications at TCP Port 8080 / UDP Port 3478. So if router can't talk to the switch they can't adopt it. After I found a bunch of blocked traffic in Firewalla it was a quick fix by moving all these network devices to a new group and set a new rule there. Now everything seems to run smoothly.
