You can register the external IP address of your Firebox or XTM device with the dynamic Domain Name System (DNS) service DynDNS.org. A dynamic DNS service makes sure that the IP address attached to your domain name changes when your ISP gives your device a new IP address. This feature is available in either mixed routing or drop-in network configuration mode.
If you use this feature, your Firebox or XTM device 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 at an interval of every twenty days. If you make any changes to your DynDNS configuration on your Firebox or XTM device, or if you change the IP address of the default gateway, it updates DynDNS.com immediately.
