addresses; make sure the LAN Client is in the same subnet as this
broadband router if you want the router to be your LAN client’s default
gateway
Lease Time

address. In the Lease Time setting you can specify the time period that the
DHCP lends an IP address to your LAN clients. The DHCP will change your
LAN client’s IP address when this time threshold period is reached

address.
