6.4.4.5.3.1.3 Configuration | Network | Routing | DHCP
DHCP (Dynamic Host Configuration Protocol) allows a device to be configured automatically,
eliminating the need for intervention by a network administrator, and provides a server located
at the hub for keeping track of devices that have been connected to the network. This prevents
two devices from accidentally being configured with the same IP Address.

DHCP Relay
The CDM-840 DHCP Relay feature allows the operator to deploy a single DHCP server at the hub
that manages all of the devices throughout the operator's remote networks. When a device on
the CDM-840 network issues a DHCP request, it is relayed to the DHCP server as specified by the
"Relay IP Address". The DHCP response is then sent directly to the requesting device.
• Relay Feature – Use the drop-down list to select the DHCP Relay feature as Enable or
Disable.
• Relay IP Address – Specify the IP Address to be used for the DHCP server at the hub in the
form XXX.XXX.XXX.XXX.
