The DR814Q offers the DHCP relay function to forward packets between a DHCP client 

and a DHCP server that are in different network segments, thereby making DHCP 

clients on multiple networks use the DHCP server across network segments. 

To allow communications between DHCP clients with a DHCP server through the relay 

function of the DR814Q, select the DHCP Relay option in the [DHCP] status section, 

and then type the IP address of the DHCP server in the corresponding field. 

 

To make DHCP relay work properly, note to disable NAT and the firewall on the 

corresponding service interface, that is, the service interface set for the DHCP server in 

route configuration.

To disable NAT, click the [NAT] tab on the security setup page, and then set [NAT 

Setting] as Disable for the corresponding interface.

Click the [DHCP Clients] tab of the LAN setup page to enter the DHCP client setting 

page shown in Figure 4-15. This page provides the current IP address assignment 

information of the DHCP server, including the host name, IP address and MAC address.
