DHCP
The DHCP page is used to adjust the settings used by the router’s built in DHC
P Server which assigns IP addresses to locally
connected devices. To access the LAN configuration page, click on the Networking menu at the top of the screen, click on the LAN
menu on the left then select the DHCP menu item.
DHCP relay configuration
In advanced networks configurations where the NTC-140-01 router should not be responsible for DHCP assignment, but instead an
existing DHCP server is located on the Wireless WAN or LAN connections, the clients behind the NTC-140-01 router are able to
communicate with the DHCP server when DHCP relay is enabled. This enables the NTC-140-01 router to accept client broadcast
messages and to forward them onto another subnet.
To configure the router to act as a DHCP relay agent click the DHCP relay toggle key to turn it ON and enter the DHCP server
address into the DHCP server address field. DHCP relay is disabled by default.
