35.6.3 DNS Command Example

This command sets an A record that specifies the mapping of a fully qualified domain name

(www.abc.com) to an IP address (210.17.2.13).

35.7 SNAT 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.

[no] ip dns server zone-forwarder

{<1..32>|append|insert <1..32>}

{domain_zone_name|*} interface interface_name

Sets a domain zone forwarder record that

specifies a fully qualified domain name. You can

also use a star (*) if all domain zones are served

by the specified DNS server(s).

domain_zone_name: This is a domain zone, not

a host. For example, zyxel.com.tw is the domain

zone for the www.zyxel.com.tw fully qualified

domain name. For example, whenever the

ZyWALL receives needs to resolve a

zyxel.com.tw domain name, it can send a query

to the recorded name server IP address.

interface_name: This is the interface through

which the ISP provides a DNS server. The

interface should be activated and set to be a

DHCP client.

The

no command deletes a zone forwarder

record.

ip dns server zone-forwarder

{<1..32>|append|insert <1..32>}

{domain_zone_name|*} user-defined w.x.y.z

[private | interface {interface_name | auto}]

Sets a domain zone forwarder record that

specifies a DNS server’s IP address.

private | interface: Use private if the

ZyWALL connects to the DNS server through a

VPN tunnel. Otherwise, use the interface

command to set the interface through which the

ZyWALL sends DNS queries to a DNS server.

The auto means any interface that the ZyWALL

uses to send DNS queries to a DNS server

according to the routing rule.

ip dns server zone-forwarder move <1..32> to

<1..32>

Changes the index number of a zone forwarder

record.

no ip dns server rule <1..32> Deletes a service control rule.
