DNS Settings

The DNS Settings page provides the option of setting up a

name server for the Quadro. It offers the following components:

The Nameserver Assignment radio buttons are as follows:

• The Dynamically by provider selection automatically

configures the assignment of the name server address

from the provider party.

• Fixed Nameserver address is a manually selected name

server. The Nameserver text field requires the IP address

of an external name server. The Alternative Nameserver

text field requires the IP address of the secondary name

server. The Alternative Nameserver is used if the main

name server cannot be accessed.

DNS Server Settings

The DNS Server on the Quadro provides the services to the hosts in the Quadro’s LAN. With this service, Quadro returns the correct IP address to

the requested domain name, so that any device in the LAN can be accessed by its hostname or alternative alias name.

The DNS Server Settings page is used to configure DNS server settings on the Quadro and to define a list of aliases for the devices in the Quadro’s

LAN. This page contains the following components:

Zone field displays the Quadro’s host domain name as it is

configured in the

System Configuration Wizard.

Time to live (TTL) text field indicates the time (in seconds)

during which the DNS server will keep the resolved names in its

cache. During this time the same address will be resolved from

the cache of the DNS server. When this timeout expires, the

requested address will be resolved newly.

Mail Exchange (MX) text field indicates the mail server’s

hostname. When resolving the email address, the reference will

go to the mail server defined in this field, before being sent out

to the external network. The value in this field will be used in the

MX record in the DNS server on the Quadro.

The table on this page lists aliases for each of the device in the

Quadro’s LAN to be resolves through the DNS server.
