Table 200 System > DNS
LABEL | DESCRIPTION |
Address/PTR | This record specifies the mapping of a fully qualified domain name (FQDN) to an IP |
Record | 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 |
| top level domain. |
|
|
# | This is the index number of the address/PTR record. |
|
|
FQDN | This is a host’s fully qualified domain name. |
|
|
IP Address | This is the IP address of a host. |
|
|
Add icon | Click the Add icon in the heading row to open a screen where you can add a new |
| address/PTR record. Refer to Table 201 on page 583 for information on the fields. |
| 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. |
|
|
Domain Zone | This specifies a DNS server’s IP address. The ZyWALL can query the DNS server |
Forwarder | 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. |
|
|
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. 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. |
