Primary

Use these fields to set how the ZyWALL determines the IP address that is

 

Binding

mapped to your domain name in the DDNS server. The ZyWALL uses the

 

Address

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.

 

 

 

 

Backup

Use these fields to set an alternate interface to map the domain name to

 

Binding

when the interface specified by the Primary Binding Interface

 

Address

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. Select None to not use a backup address.
