Override DHCP Default Gateway
If you are using a DHCP range for another device
or subnet you can override the Controller settings using
Networks – Server – DHCP - Override DHCP Default Gateway.
Normal behavior is the DHCP pool must be in the Controller
subnet, and the DHCP Default Gateway is the Controller LAN IP.
Aggressive DHCP Conflict Detection
The DHCP specification calls for clients, not the
server, to detect if there is an unexpected IP Address Conflict in
an offered DHCP lease and decline the lease. Enabling this option
adds an additional check by the DHCP Server itself for conflicts
before a lease is offered.
