44.5.2 Configuring the DNS Screen

Click System > DNS to change your ZyWALL's DNS settings. Use the DNS screen to
configure the ZyWALL to use a DNS server to resolve domain names for ZyWALL system
features like VPN, DDNS and the time server. You can also configure the ZyWALL to accept
or discard DNS queries. Use the Network > Interface screens to configure the DNS server
information that the ZyWALL sends to the specified DHCP client devices.

DESCRIPTION
This record specifies the mapping of a fully qualified domain name (FQDN) to an IP
address. An FQDN consists of a host and domain name. For example,
www.zyxel.com.tw is a fully qualified domain name, where "www" is the host,
"zyxel" is the third-level domain, "com" is the second-level domain, and "tw" is the
top level domain.
This is the index number of the address/PTR record.
This is a host's fully qualified domain name.
This is the IP address of a host.
Click the Add icon in the heading row to open a screen where you can add a new
address/PTR record. Refer to
Click the Edit icon to go to the screen where you can edit the record.
Click the Delete icon to remove an existing record. A window display asking you to
confirm that you want to delete the record. Note that subsequent records move up
by one when you take this action.
This specifies 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.
When the ZyWALL needs to resolve a domain zone, it checks it against the domain
zone forwarder entries in the order that they appear in this list.
This is the index number of the domain zone forwarder record. The ordering of your
rules is important as rules are applied in sequence.
A hyphen (-) displays for the default domain zone forwarder record. The default
record is not configurable. The ZyWALL uses this default record if the domain zone
that needs to be resolved does not match any of the other domain zone forwarder
records.
