The following table describes the labels in this screen.
First DNS Server
Second DNS Server
Third DNS Server
Select
Obtained From ISP
if your ISP dynamically assigns DNS server information
(and the NBG6716's WAN IP address). The field to the right displays the (read-only)
DNS server IP address that the ISP assigns.
Select
User-Defined
if you have the IP address of a DNS server. Enter the DNS server's
IP address in the field to the right. If you chose
User-Defined
, but leave the IP address
set to 0.0.0.0,
User-Defined
changes to
None
after you click
Apply
. If you set a
second choice to
User-Defined
, and enter the same IP address, the second
User-
Defined
changes to
None
after you click
Apply
.
Select
DNS Relay
to have the NBG6716 act as a DNS proxy. The NBG6716's LAN IP
address displays in the field to the right (read-only). The NBG6716 tells the DHCP
clients on the LAN that the NBG6716 itself is the DNS server. When a computer on the
LAN sends a DNS query to the NBG6716, the NBG6716 forwards the query to the
NBG6716's system DNS server (configured in the
WAN > Internet Connection
screen) and relays the response back to the computer. You can only select
DNS Relay
for one of the three servers; if you select
DNS Relay
for a second or third DNS server,
that choice changes to
None
after you click
Apply
.
Select
None
if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
Apply
Click
Apply
to save your changes back to the NBG6716.

to begin configuring this screen afresh.
