Profile

 

 

 

Profile Name

When you are adding a DDNS entry, type a descriptive name for this DDNS entry in

 

the ZyWALL. You may use 1-31 alphanumeric characters, underscores(_), or

 

dashes (-), but the first character cannot be a number. This value is case-sensitive.

 

This field is read-only when you are editing an entry.

 

 

DDNS Type

Select the type of DDNS service you are using.

 

 

Username

Type the user name used when you registered your domain name. You can use up

 

to 31 alphanumeric characters and the underscore. Spaces are not allowed.

 

For a Dynu DDNS entry, this user name is the one you use for logging into the

 

service, not the name recorded in your personal information in the Dynu website.

 

 

Password

Type the password provided by the DDNS provider. You can use up to 64

 

alphanumeric characters and the underscore. Spaces are not allowed.

 

 

DDNS Settings

Click Advanced to display more settings. Click Basic to display fewer settings.

 

 

Domain name

Type the domain name you registered. You can use up to 255 characters.

 

 

Primary Binding

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

Address

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.

 

 

Backup Binding

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

Address

interface specified by the Primary Binding Interface 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.
