Hi! I am a newbie Unifi network admin with a few sites for friends, family, colleagues and a couple of small businesses (restaurants) on a self hosted Unifi controller I’ve had for a few years.
L3 adoption of new devices is very straight forward up until the adopted devices update and/or reboot, then they revert back to the default inform URL. This has caused me lots of troubleshooting and head banging/scratching.
Unifi support tells me to use DHCP option 43 (which is not an option for me due to different clients’ non-Ubiquiti gateways/routers). DNS resolving of “Unifi” is not an option for me at all sites, and I think the set-inform command should be persistent.
Has anyone here stumbled upon this issue and found a resolution? I really love Unifi switches and APs, but their gateways do not offer the features or flexibility I need.
This was the (disappointing) response I got from UniFi:
We do not recommend making configuration changes via secure-shell because any configuration applied via secure-shell may vanish after reboot.
If you want to adopt the device using L3-adoption, we strongly recommend using DHCP option 43. This option leverages your DHCP server to inform your UniFi device of the location of the machine running the Network Application remotely. Those with a UniFi Gateway can easily accomplish this by entering the IP address of the remote Network Application in Option 43 Application Host Address field located in the Network Settings .
For those using a third-party gateway or DHCP server, we recommend consulting your manufacturer’s documentation to learn more.
