Configuring a DDNS

This section describes how to configure a DDNS.

Creating a DDNS

To create a DDNS, take the following steps:

1. On the Navigation pane, click Configure > Network > Network to visit the Network page.
2. On the Task tab in the right auxiliary pane, click DDNS.
3. In the DDNS List dialog, click New.
4. In the DDNS Configuration dialog, configure options.
   • DDNS name: Specifies the name of DDNS.
   • Interface: Specifies the interface to which DDNS is applied.
   • Host name: Specifies the domain name obtained from the DDNS provider.
   • Provider: Specifies a DDNS provider. Choose one from the drop-down list.
   • Server name: Specifies a server name for the configured DDNS.
   • Server port: Specifies a server port number for the configured DDNS. The value range is 1 to 65535.
   • Min update interval: When the IP address of the interface with DDNS enabled changes, system will send an update request to the DDNS server. If the request is not responded, system will send the request again according to the configured min update interval. For example, if the min update interval is set to 5 minutes, then system will send the second request 5 minutes after the first request failure; if failed again, system will send the request again 10 (5x2) minutes later; and 20 (10x2) minutes later, so and forth. The value will not increase anymore when reaching 120, that is, system will send the request at a fixed interval of 120 minutes. Type the min update interval into the box. The value range is 1 to 120 minutes. The default value is 5.
   • Max update interval: On the condition that IP address has not changed, system will send an update request to the DDNS server at the max update interval. Type the max update interval into the box. The value range is 24 to 8760 hours. The default value is 24.
   • Username: Specifies the username registered in the DDNS provider.
   • Password: Specifies the corresponding password.
   • Confirm password: Enter the password again to confirm.
   • OK: Saves the changes and returns to the previous dialog/page.
   • Cancel: Cancels the changes and returns to the previous dialog/page.
5. Click OK to close the dialog and return to DDNS List.

Note: The Server name and Server port in the configuration options must be the corresponding name and port of the DDNS server. Do not configure these options if the exact information is unknown. The server will return the name and port information automatically after connection to the DDNS server has been established successfully.
