DESCRIPTION
Address/PTR
Record
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.

#

FQDN
This is a host’s fully qualified domain name.
IP Address
This is the IP address of a host.
Domain Zone
Forwarder
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.

and click
Move
to display a field to type a number for where you want
to put it and press [ENTER] to move the rule to the number that you
typed.
#
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.
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.
A “*” means all domain zones.
Type
This displays whether the DNS server IP address is assigned by the ISP
dynamically through a specified interface or configured manually
(
User-Defined
).
