DESCRIPTION
DNS Servers
Assigned by DHCP
Server
The device passes a DNS (Domain Name System) server IP address to the
DHCP clients.
Selected Interface
Select an interface from the drop-down list box to configure the DNS servers for
the specified interface.
#
This is the number of an individual entry.
DNS
These read-only labels represent the DNS servers.
IP
Select
From ISP
if your ISP dynamically assigns DNS server information (and
the device's WAN IP address). Use the drop-down list box to select a DNS
server IP address that the ISP assigns in the field to the right.
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 device act as a DNS proxy. The device's LAN,
DMZ or WLAN IP address displays in the field to the right (read-only). The
device tells the DHCP clients on the LAN, DMZ or WLAN that the device itself is
the DNS server. When a computer on the LAN, DMZ or WLAN sends a DNS
query to the device, the device forwards the query to the device's system DNS
server (configured in the
DNS System
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. You must have
another DHCP sever on your LAN, or else the computers must have their DNS
server addresses manually configured. 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 device.
Reset
Click
Reset
to begin configuring this screen afresh.
