43.5.7 Domain Zone Forwarder

A domain zone forwarder contains a DNS server’s IP address. The ZyWALL can query the DNS server to resolve domain zones for features like VPN, DDNS and the time server. A domain zone is a fully qualified domain name without the host. For example, zyxel.com.tw is the domain zone for the www.zyxel.com.tw fully qualified domain name.

DESCRIPTION

Domain Zone

A domain zone is a fully qualified domain name without the 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.

 

Enter * if all domain zones are served by the specified DNS server(s).

 

 

DNS Server

Select DNS Server(s) from ISP if your ISP dynamically assigns DNS server

 

information. You also need to select an interface through which the ISP provides

 

the DNS server IP address(es). The interface should be activated and set to be a

 

DHCP client. The fields below display the (read-only) DNS server IP address(es)

 

that the ISP assigns. N/A displays for any DNS server IP address fields for which

 

the ISP does not assign an IP address.

 

Select Public DNS Server if you have the IP address of a DNS server. Enter the

 

DNS server's IP address in the field to the right. The ZyWALL must be able to

 

connect to the DNS server without using a VPN tunnel. The DNS server could be

 

on the Internet or one of the ZyWALL’s local networks. You cannot use 0.0.0.0.

 

Select Private DNS Server if you have the IP address of a DNS server to which

 

the ZyWALL connects through a VPN tunnel. Enter the DNS server's IP address in

 

the field to the right. You cannot use 0.0.0.0.
