DESCRIPTION
Enter your user name. You can use up to 31 alphanumeric characters (and the

Enter the password associated with the user name above. You can use up to 31
alphanumeric characters (and the underscore). Spaces are not allowed.
Enter the host names in these fields.
Select the type of service that you are registered for from your Dynamic DNS
service provider.
Select Dynamic if you have the Dynamic DNS service.
Select Static if you have the Static DNS service.
Select Custom if you have the Custom DNS service.
This option is available when Custom is selected in the DDNS Type field.
Check with your Dynamic DNS service provider to have traffic redirected to a
URL (that you can specify) while you are off line.
Select the check box to enable DYNDNS Wildcard.
Select the WAN interface to use for updating the IP address of the domain
name.
Select Use WAN IP Address to have the ZyWALL update the domain name
with the WAN interface's IP address.
Select Use User-Defined and enter the IP address if you have a static IP
address.
Select Let DDNS Server Auto Detect only when there are one or more NAT
routers between the ZyWALL and the DDNS server. This feature has 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.
Select this check box to enable the high availability (HA) feature. High
availability has the ZyWALL update a domain name with another interface's IP
address when the normal WAN interface does not have a connection.
If the WAN interface specified in the WAN Interface field does not have a
connection, the ZyWALL will attempt to use the IP address of another WAN
interface to update the domain name.
When the WAN interfaces are in the active/passive operating mode, the
ZyWALL will update the domain name with the IP address of whichever WAN
interface has a connection, regardless of the setting in the WAN Interface field.
Disable this feature and the ZyWALL will only update the domain name with an
IP address of the WAN interface specified in the WAN Interface field. If that
WAN interface does not have a connection, the ZyWALL will not update the
domain name with another port's IP address.
Note: If you enable high availability, DDNS can also function
when the ZyWALL uses the dial backup port. DDNS does
not function when the ZyWALL uses traffic redirect.
