The DHCP lease time is the amount of time that the Gateway retains the IP address for the client devices in the network. If the Gateway does not see the client device in the network before the DHCP lease time expires, the IP address is released and available for other client devices to use. This document describes how to change the DHCP lease time in the Gateway.
