5.1.4 DHCP Reservation
DHCP reservation, also known as static DHCP, allows the ZyXEL Device to assign specific IP
addresses on the LAN to specific individual computers based on their MAC addresses.
Configure DHCP Reservation settings in the LAN screen. You can also view the list of
reserved IP addresses in this screen.

DHCP Lease
Time
Specify the time (in minutes) a DHCP client is allowed to use the assigned IP
address from the ZyXEL Device. Once the lease time is up, the DHCP client has to
renew the lease.
Always Broadcast Some older DHSP client software disable DHCP broadcasting, thus some
computers may not be able to obtain an IP address from the ZyXEL Device.
Select this option to set the ZyXEL Device to broadcast DHCP replies. This
ensures that all LAN computers can get an IP address at the cost of increased
broadcast traffic on the LAN.
