DESCRIPTION

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 Backup Binding Address

 

Interface field.

 

Auto -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.

 

 

Enable Wildcard

This option is only available with a DynDNS account.

 

Enable the wildcard feature to alias subdomains to be aliased to the same IP

 

address as your (dynamic) domain name. This feature is useful if you want to be

 

able to use, for example, www.yourhost.dyndns.org and still reach your hostname.

 

 

Mail Exchanger

This option is only available with a DynDNS account.

 

DynDNS can route e-mail for your domain name to a mail server (called a mail

 

exchanger). For example, DynDNS routes e-mail for john-

 

doe@yourhost.dyndns.org to the host record specified as the mail exchanger.

 

If you are using this service, type the host record of your mail server here.

 

Otherwise leave the field blank.

 

See www.dyndns.org for more information about mail exchangers.

 

 

Backup mail

This option is only available with a DynDNS account.

exchanger

Select this check box if you are using DynDNS’s backup service for e-mail. With

 

this service, DynDNS holds onto your e-mail if your mail server is not available.

 

Once your mail server is available again, the DynDNS server delivers the mail to

 

you. See www.dyndns.org for more information about this service.
