Host Name

Enter your host name in this field.

DDNS Type

Press [SPACE BAR] and then [ENTER] to select DynamicDNS if you have the 
Dynamic DNS service. 
Select StaticDNS if you have the Static DNS service.
Select CustomDNS if you have the Custom DNS service.

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

Line Option 

This field is only available when CustomDNS is selected in the DDNS Type field. 
Press [SPACE BAR] and then [ENTER] to select Yes. When Yes is selected, 

http://

www.dyndns.com/

 traffic is redirected to a URL that you have previously specified 

(see 

www.dyndns.com

 for details). 

Bind WAN

Enter the WAN to use for updating the IP address of the domain name.

HA

Press [SPACE BAR] and then [ENTER] to select Yes to enable the high availability 
(HA) feature. 
If the WAN specified in the Bind WAN field does not have a connection, the ZyWALL 
will attempt to use the IP address of another WAN to update the domain name.
When the WAN s are in the active/passive operating mode, the ZyWALL will update 
the domain name with the IP address of whichever WAN has a connection, 
regardless of the setting in the Bind WAN field.
Clear this check box and the ZyWALL will not update the domain name with an IP 
address if the WAN specified in the Bind WAN field does not have a connection.

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.
