Use the Networking > WAN > DDNS page to configure Dynamic DNS (DDNS). DDNS is an Internet service that allows routers with varying public IP addresses to be located using Internet domain names. If your ISP has not provided you with a static IP and your WAN connection is configured to use DHCP to obtain an IP address dynamically, then DDNS provides the domain name to map the dynamic IP address for your website. To use DDNS, you must set up an account with a DDNS provider such as DynDNS.com.
The Status column
displays the status of DDNS service. Click Active
to manually update the IP address of the WAN interface to the user
• Non-active: The DDNS service is not active (DDNS daemon does not start).
• Active (initial): The DDNS daemon starts but the DDNS updating process is not complete yet.
• Active (updated WANx): The DDNS updating process is complete and the address of the WAN interface is updated to the user-specified domain name.
Adding or modifying a DDNS service
Click Add to add a new DDNS service. To edit an entry, click the Edit (pencil) icon. To delete an entry, click the Delete (x) icon.
1. Enter the following information:
• Service: Specify the provider for your DDNS service. You can choose either DynDNS or No-IP service.
NOTE: You must sign up for an account with either one of these providers before you can use this service.
• Active on Startup: Check this box to activate the DDNS service when the security appliance starts up.
• WAN Interface: Choose the WAN port for the DDNS service. Traffic for the DDNS services will pass through the specified WAN port.
NOTE: If the WAN redundancy is set as the Failover mode, this option is grayed out. When WAN failover occurs, DDNS will switch traffic to the active WAN port.
• User Name: Enter the username of the account that you registered in the DDNS provider.
• Password: Enter the password of the account that you registered in the DDNS provider.
• Host and Domain Name: Enter the complete host name and domain name for the DDNS service, for example: name.dyndns.org.
• Wildcards: Check this box to allow all subdomains of your DDNS host name to share the same public IP address as the host name.
• Update: Check this box to update the host information every week.
