Primary Binding
Address
Use these fields to set how the ZyWALL determines the IP address that is mapped to
your domain name in the DDNS server. The ZyWALL uses the Backup Binding
Address if the interface specified by these settings is not available.
Interface Select the interface to use for updating the IP address mapped to the domain name.
Select Any to let the domain name be used with any interface.
IP Address The options available in this field vary by DDNS provider.
Interface -The ZyWALL uses the IP address of the specified interface. This option
appears when you select a specific interface in the Primary Binding Address
Interface field.
Auto - If the interface has a dynamic IP address, the DDNS server checks the source
IP address of the packets from the ZyWALL for the IP address to use for the domain
name. You may want to use this if there are one or more NAT routers between the
ZyWALL and the DDNS server.
Note: The ZyWALL may not determine the proper IP address if there is an HTTP proxy
server between the ZyWALL and the DDNS server.
Custom - If you have a static IP address, you can select this to use it for the domain
name. The ZyWALL still sends the static IP address to the DDNS server.
Custom IP This field is only available when the IP Address is Custom. Type the IP address to use
for the domain name.
