Table 116 ADVANCED > DNS > Insert (Name Server Record)
LABEL | DESCRIPTION |
Domain Zone | This field is optional. |
| 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. |
| Leave this field blank if all domain zones are served by the specified DNS server(s). |
|
|
DNS Server | Select the DNS Server(s) from ISP radio button if your ISP dynamically assigns |
| DNS server information. The fields below display the |
| 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. N/A displays for all of the DNS |
| server IP address fields if the ZyWALL has a fixed WAN IP address. |
| Select Public DNS Server if you have the IP address of a DNS server. The IP |
| address must be public or a private address on your local LAN. Enter the DNS |
| server's IP address in the field to the right. |
| Public DNS Server entries with the IP address set to 0.0.0.0 are not allowed. |
| Select Private DNS Server if the DNS server has a private IP address and is located |
| behind a VPN peer. Enter the DNS server's IP address in the field to the right. |
| With a private DNS server, you must also configure the first DNS server entry for the |
| LAN, DMZ and/or WLAN in the DNS DHCP screen to use DNS Relay. |
| You must also configure a VPN rule since the ZyWALL uses a VPN tunnel when it |
| relays DNS queries to the private DNS server. The rule must include the LAN IP |
| address of the ZyWALL as a local IP address and the IP address of the DNS server |
| as a remote IP address. |
| Private DNS Server entries with the IP address set to 0.0.0.0 are not allowed. |
