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

¾ DHCP Relay: Select Relay, then you will see the next screen (shown in Figure 4-11), and the

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.
