When performing DNS relay, the ADSL Modem/Router
itself is not a DNS server, it forwards DNS requests from LAN PCs
to a DNS server at the ISP. It then relays the DNS response to the
PCs.
The ADSL Modem/Router learns DNS address in either
or both of the following ways:
Learned through PPP

Follow these steps to configure DNS relay:
1. Configure the LAN PCs.
Just set the LAN PCs as DHCP clients of the ADSL
Modem/Router.
2. On the ADSL Modem/Router, go to
LAN
>
DHCP Server
, enter the LAN IP address (e.g.,
192.168.1.1
) or
0.0.0.0
as the DNS address in the DHCP
server pool.
By default, 0.0.0.0 is already set as the DNS of the DHCP
pool.
3. Determines how the router will learn the DNS server
address:
Option 1: Using a PPP connection to learn the DNS
Use DNS
must be enabled in the PPP interface properties.
Go to
Routing
>
PPP
and check the PPP interface details. If
Use DNS
is disabled, you must delete the interface and
recreate it with the new setting.
