2.3 DHCP Configuration
The scope of DHCP client pool that corresponds to the selected interface and subnet are defined in this menu.
Lease (D) is the duration that the DHCP server grants to the DHCP client permission to use a particular IP
address. Lease (M) is the maximum lease time.
Each Ethernet or wireless interface can be the gateway of its own subnet. Hence there can be three subnet
domains in one AP in routing mode. This DHCP configuration is only available when SYSTEM is operating
in router mode.
