 [[https://unifi-network.ui.com/|Ubiquiti UniFi]] is a line of networking equipment including Wi-Fi access points and switches.  Most of these devices need a "UniFi Controller" to allow the device to be configured and managed.  A LXC container in AstLinux offers a good method to act as a local UniFi Controller for Wi-Fi access points and switches.

+**UniFi DHCP option 43, Controller Assignment**
+If the UniFi controller is not in the same subnet (broadcast domain) as your UniFi devices, before adopting UniFi devices you can edit your ''/mnt/kd/dnsmasq.static'' file with the following:
+  ## UniFi DHCP option 43, Controller Assignment
+  dhcp-option=vendor:ubnt,1,192.168.200.20
+Replace the ''192.168.200.20'' IP address with your controller's static address.  In the web interface, select "Restart DNS & DHCP" to apply the change to the dnsmasq configuration.
