DESCRIPTION

Domain Name

Enter the domain name you want to resolve.

You can use the wildcard character, an “*” (asterisk) as the left most part of a domain

name, such as *.example.com. The Router forwards DNS queries for any domain name

ending in example.com to the WAN interface specified in this route.

IP Subnet Mask

Enter the subnet mask of the network for which to use the DNS route.

Interface

Select a WAN interface through which the matched DNS query is sent. You must have

the WAN interface(s) already configured in the

WAN

screen.

DNS Route

10.1 Overview

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.

In addition to the system DNS servers, each WAN interface (service) is set to have its own static or

dynamic DNS server list. You can configure a DNS static route to forward DNS queries for certain

domain names through a specific WAN interface to its DNS servers. The Router uses a system DNS

server (in the order you specify in the

Broadband

screen) to resolve domain names that do not

match any DNS routing entry. After the Router receives a DNS reply from a DNS server, it creates a

new entry for the resolved IP address in the routing table.

10.2

The DNS Route Screen

The

DNS Route

screens let you view and configure DNS routes on the Router. Click

Network

Setting > Routing > DNS Route

to open the

DNS Route

screen. A DNS route forwards DNS queries

for a specific domain name through a specific WAN interface to its DNS server.
