4.2.8 DHCP Relay
Configure DHCP Relay on this page. DHCP Relay is used to forward and to transfer DHCP messages
between the clients and the server when they are not on the same subnet domain.
The DHCP option 82 enables a DHCP relay agent to insert specific information into a DHCP request
packets when forwarding client DHCP packets to a DHCP server and remove the specific information
from a DHCP reply packets when forwarding server DHCP packets to a DHCP client. The DHCP server
can use this information to implement IP address or other assignment policies. Specifically the option
works by setting two sub-options:
 Circuit ID (option 1)
 Remote ID (option2).
