About the Dynamic DNS Service
You can register the external IP address of your Firebox with the dynamic Domain Name System (DNS) service DynDNS (dyn.com). A dynamic DNS service makes sure that the IP address attached to your domain name changes when your ISP gives your Firebox a new IP address. This feature is available only in mixed routing network configuration mode.
If you use this feature, your Firebox gets the IP address of members.dyndns.org when it starts up. It makes sure the IP address is correct every time it restarts, and every twenty days. If you make any changes to your DynDNS configuration on your Firebox, or if you change the IP address of the external interface, it immediately sends updated information to dyn.com.
