Benefits of specifying DNS servers and adding routes
When you first log on to the appliance, the DNS and Routing page displays the servers and routes that you
specified in the Setup Wizard. Use this page to review the entries, add or remove routes and servers,
and change their priority.
Domain Name System (DNS) servers translate or "map" the names of network devices into IP
addresses. Use the arrows to move the servers up and down the list. The first server in the list must
be your nearest, or most reliable server. If the first server cannot resolve the request, the appliance
contacts the second server. If no servers in the list can resolve the request, the appliance forwards the
request to the DNS root name servers on the Internet.
