Note:
If Use Auto Discovered DNS Server Only is selected in DNS Relay, this modem router will
accept the first received DNS assignment from one of the PPPoA, PPPoE or MER/DHCP
enabled PVC(s) during the connection establishment. If Use User Discovered DNS Server
Only is selected in DNS Relay, it is necessary for you to enter the primary and optional
secondary DNS server IP addresses. After typing in the address, click SAVE to save it and
invoke it.
DHCP Relay: Select Relay, then you will see the following 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 that 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.
