Use these screens to configure the mail server settings and alert settings.
24.5.1 Mail Server
Use this screen to configure a mail server so you can receive reports and notification emails such as
when your password is about to expire. After you configure the screen, you can test the settings in
IP Address The options available in this field vary by DDNS provider.
Interface -The Zyxel Device 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 Zyxel Device
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 Zyxel Device and the DDNS server.
Note: The Zyxel Device may not determine the proper IP address if there is an
HTTP proxy server between the Zyxel Device and the DDNS server.
Custom - If you have a static IP address, you can select this to use it for the domain name.
The Zyxel Device 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.
DYNDNS Server Type the IP address of the server that will host the DDSN service.
URL Type the URL that can be used to access the server that will host the DDSN service.
Additional DDNS
Options
These are the options supported at the time of writing:
• dyndns_system to specify the DYNDNS Server type - for example, dyndns@dyndns.org
• ip_server_name which should be the URL to get the server’s public IP address - for
example, http://myip.easylife.tw/
Advanced Settings Click the arrow in the Advanced Settings field to show the following options.
Enable Wildcard 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 DynDNS can route email for your domain name to a mail server (called a mail exchanger).
For example, DynDNS routes email 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
Exchanger
Select this check box if you are using DynDNS’s backup service for email. With this service,
DynDNS holds onto your email 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.
