provides two DNS servers.
¾ DHCP Relay: Select Relay, then you will see the next screen, and the modem router will work
as a DHCP Relay. A DHCP relay is a computer that forwards DHCP data between computers
that request IP addresses and the DHCP server that assigns the addresses. Each of the
device's interfaces can be configured as a DHCP relay. If it is enabled, the DHCP requests
from local PCs will forward to the DHCP server runs on WAN side. To have this function
working properly, please run on router mode only, disable the DHCP server on the LAN port,
and make sure the routing table has the correct routing entry.

the LAN as "Obtain an IP Address automatically".

3) If you select Disabled, the DHCP function will not take effect.
