Cisco SA 500 Series Security Appliances Administration Guide
Dynamic DNS (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 get an IP address dynamically, then DDNS allows you to have a virtual static
address for your website. To use DDNS, you must setup an account with a DDNS
provider such as DynDNS.com.
Click Networking on the menu bar, and then click Dynamic DNS in the navigation
tree.
The Dynamic DNS page appears.
In the WAN Mode area, the Current WAN Mode is displayed.
In the Dedicated WAN (DDNS Status) area or the Optional WAN (DDN Status)
area, enter the following information:
• Select the Dynamic DNS Service: Choose None or choose DynDNS.com.
• Host and Domain Name: Specify the complete Host Name and Domain
Name for the DDNS service.
• User Name: Enter the DynDNS account User Name.
• Password: Enter the password for the DynDNS account.
• Use wildcards: Check this box to allow all subdomains of your DynDNS Host
Name to share the same public IP as the Host Name. This option can be
enabled here if not done on the DynDNS Web site.
• Update every 30 days: Check this box to allow the security appliance to
update the host information on DynDNS and keep the subscription active
after the 30 day trial.
Click Apply to save your settings, or click Reset to revert to the saved settings.
