The following table describes the labels in this screen.
Table 114
System 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 (read-only) DNS server IP
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 in
the
DNS LAN
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.

to save your changes back to the ZyWALL.
