DNS server
Third system
DNS server
DNS (Domain Name System) is for mapping a domain
name to its corresponding IP address and vice versa.
The DNS server is extremely important because
without it, you must know the IP address of a machine
before you can access it. The Business Secure Router
uses a system DNS server (in the order you specify
here) to resolve domain names for VPN, DDNS and
the time server.
Press [SPACE BAR] and then [ENTER] to select an
option. 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 select
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. The IP address can be public or a private
address on your local LAN. Enter the DNS server's IP
address in the field to the right.
A
User-Defined
entry with the IP address set to
0.0.0.0 changes to
None
after you save your changes.
A duplicate
User-Defined
entry 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 system DNS server,
you must use IP addresses when configuring VPN,
DDNS and the time server.
Select
Private DNS
if the DNS server has a private IP
address and is located behind a VPN peer. Enter the
DNS server IP address in the field to the right.
With a private DNS server, you must also configure
the first DNS server entry in SMT menu 3.1 to use
DNS Relay
.
