Primary Binding | Use these fields to set how the ZyWALL determines the IP address that is mapped to |
Address | your domain name in the DDNS server. The ZyWALL uses the Backup Binding |

|
|

IP Address | The options available in this field vary by DDNS provider. |
| Interface |
| 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. |
