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-
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
Exchanger
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.
