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 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. 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.
This displays whether the DNS server IP address is assigned by the ISP
dynamically through a specified interface or configured manually.
