First DNS Server
Second DNS
Server
Third DNS Server
The Business Secure Router passes a DNS
(Domain Name System) server IP address (in the
order you specify here) to the DHCP clients.
Select
From ISP
if your ISP dynamically assigns
DNS server information (and the Business Secure
Router's WAN IP address). The
IP Address
field
below displays the (read-only) DNS server IP
address that the ISP assigns. If you chose
From
ISP
, but the Business Secure Router has a fixed
WAN IP address,
From ISP
changes to
None
after
you save your changes. If you chose
From ISP
for
the second or third DNS server, but the ISP does
not provide a second or third IP address,
From ISP
changes to
None
after you save your changes.
Select
User-Defined
if you have the IP address of a
DNS server. Enter the DNS server's IP address in
the
IP Address
field below. If you chose
User-Defined
, but leave the IP address set to
0.0.0.0,
User-Defined
changes to
None
after you
save your changes. If you set a second choice to
User-Defined
, and enter the same IP address, the
second
User-Defined
changes to
None
after you
save your changes.
Select
DNS Relay
to have the Business Secure
Router act as a DNS proxy. The Business Secure
Router's LAN IP address displays in the
IP Address
field below (read-only). The Business Secure Router
tells the DHCP clients on the LAN that the Business
Secure Router itself is the DNS server. When a
computer on the LAN sends a DNS query to the
Business Secure Router, the Business Secure
Router forwards the query to the Business Secure
Router's system DNS server (configured in the
SYSTEM General
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 save your changes.
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 machine in order to
access it.
