DESCRIPTION
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.
This field is only available when the IP Address is Custom. Type the IP address to
use for the domain name.
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
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
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.
This option is only available with a DynDNS account.
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.
Click OK to save your changes back to the ZyWALL.
Click Cancel to exit this screen without saving.
