DHCP
The DHCP page is used to adjust the settings used by the router’s built in DHPC Server which assigns IP addresses to locally connected devices.
DHCP relay configuration
In advanced networks configurations where the 3G Light Industrial M2M Router should not be responsible for DHCP assignment, but instead an existing DHCP server is located on the Wireless
WAN connection, the clients behind the 3G Light Industrial M2M Router are able to communicate with the DHCP server when DHCP relay is enabled. This enables the 3G Light Industrial M2M
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.
