FIELD DESCRIPTION
Host Name Enter your host name in this field.
DDNS Type Press [SPACE BAR] and then [ENTER] to select DynamicDNS if you have a dynamic
IP address(es). Select StaticDNS if you have a static IP address(s).
Select CustomDNS to have dyns.org provide DNS service for a domain name that
you already have from a source other than dyndns.org.
Enable
Wildcard
Option
Your ZyWALL supports DYNDNS Wildcard. Press [SPACE BAR] and then [ENTER]
to select Yes or No. This field is N/A when you choose DDNS client as your service
provider.
Enable Off Line

Press [SPACE BAR] and then [ENTER] to select Yes. When Yes is selected, http://
www.dyndns.org/ traffic is redirected to a URL that you have previously specified
(see www.dyndns.org for details).
IP Address
Update Policy:
You can select Yes in either the Let DDNS Server Auto Detect field (recommended)
or the Use User-Defined field, but not both.
With the Let DDNS Server Auto Detect and Use User-Defined fields both set to No,
the DDNS server automatically updates the IP address of the host name(s) with the
ZyWALL’s WAN IP address.
DDNS does not work with a private IP address. When both fields are set to No, the
ZyWALL must have a public WAN IP address in order for DDNS to work.
Let DDNS
Server Auto
Detect
Only select this option when there are one or more NAT routers between the ZyWALL
and the DDNS server. Press [SPACE BAR] to select Yes and then press [ENTER] to
have the DDNS server automatically detect and use the IP address of the NAT router
that has a public IP address.
Note: The DDNS server may not be able to detect the proper IP
address if there is an HTTP proxy server between the ZyWALL
and the DDNS server.
Use User-
Defined
Press [SPACE BAR] to select Yes and then press [ENTER] to update the IP address
of the host name(s) to the IP address specified below.
Only select Yes if the ZyWALL uses or is behind a static public IP address.
