DHCP Relay Agent

When enabled, the DHCP relay agent forwards DHCP requests to the set DHCP server.
Click the Configure > Network > DHCP R A to configure DHCP relay agent servers and enable the DHCP relay agent.
NOTE: At least one DHCP server must be enabled before DHCP Relay Agent can be enabled.
NOTE: If the DHCP relay agent is unable to reach the external DHCP Server specified in the DHCP Server IP Address
Table, the requesting client will receive an IP address from the IP Pool table of the AP's internal DHCP Server,
even if the internal DHCP Server is disabled.
NOTE: If a client requests an available IP address from the IP Pool table of the AP's internal DHPC Server, the client will
receive this address, even if the DHCP server on the AP is disabled. To ensure that clients receive IP addresses
only from the DHCP Relay Agent, disable all entries in the IP Pool table of the AP's internal DHCP server.
The DHCP Relay functionality of the AP supports Option 82 and sends the system name of the AP (as a NAS identifier)
as a sub-option of Option 82.
The AP makes a DHCP Request for lease renewal five minutes ahead of the expiration of the Rebinding time as
specified in the DHCP Offer from the DHCP server obtained during the last renewal.
