The gateway offers a Dynamic Domain Name System (DDNS) feature. The DDNS lets you assign a fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other servers behind the gateway. Before you can use this feature, you need to sign up for DDNS service at www.dyndns.org or other DDNS service providers. Please refer to the gateway manual APPENDIX G for more DDNS service providers.
Enable Dynamic DNS. Click the checkbox to enable the DDNS service.
DDNS Account. The hostname you registered to the DDNS service provider.
Choose from list. If you found your DDNS service provider from the pull down menu, type the first part of the hostname in the input box, and select the DDNS provider.
Enter your account name. If your service provider cannot be found on the list, please type your registered full hostname in the input box.
User Name, Password. These DDNS services require you to login, please enter the your user name and password here for login.
Wild Card Enable. If you like to have an unregistered hostname followed by the registered hostname and domain name to work as well, click the Wild Card Enable checkbox.
Usage: <unregistered_hostname>.<registered_hostname and domain_name>.
For example: The registered hostname on the service provider side is xyz.dyndns.org, you can use abc.xyz.dyndns.org or abc.efg.xyz.dyndns.org as your hostname.
Mail Exchanger. If you wish to use a mail exchanger, put its hostname in the Mail Exchanger field. Others sent mails to your DDNS name will be redirected to the mail server you specified here.
Backup MX. If you need to backup the Mail Exchanger’s address while you login the DDNS service provider every time, please click the checkbox.
Update Status. The status of your DDNS service. Please refer to the gateway manual APPENDIX E for details.
Click the Update to update the DDNS service, or click Refresh to refresh display. Please do not click the Update for many times, some DDNS service providers forbid multiple successive updates from the same IP address. If you are using Static IP address as your Internet connection, please uncheck the Enable Dynamic DNS box, after a successful update to the DDNS service provider. Otherwise, the DDNS will update again with the static IP address next time you reboot the gateway. When using a dynamic IP address of the Internet port, you don’t have to worry this problem.
