Static Leases

Static IP leases are used to reserve specific IP addresses for specific devices by binding them to their MAC address.
This is useful when you have a stationary device connected to your network that you need to reach frequently, e.g.,
printer, fax, etc.
Field Name Sample Value
1. Hostname Printer
2. MAC address 10:a5:d0:70:9c:72 (192.168.1.104)

Explanation
Enables Dynamic allocation of client addresses. If this is disabled,
only clients that have static IP leases will be served
Enables DNS rebind attack protection by discarding upstream
RFC1918 responses (leave default unless necessary otherwise)
By default the router's DHCP server will not start when it is
connected to a network segment that already has a working DHCP
server. If enabled, the DHCP force function ensures that the router
will always start it's DHCP server, even if there is another DHCP
server already running in the router's network
Overrides your LAN netmask thus making the DHCP server think that
it's serving a larger or smaller network than it actually is
Additional options to be added to the DHCP server. For example with
'26,1470' or 'option:mtu, 1470' you can assign an MTU per DHCP
Explanation
