to a DNS server at the ISP. It then relays the DNS response to the
PCs.

or both of the following ways:

Follow these steps to configure DNS relay:
1. Configure the LAN PCs.
Just set the LAN PCs as DHCP clients of the RTA100+ ADSL

2. On the RTA100+ 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
