The Firebox gets the IP address of members.dyndns.org when it
starts up. The Firebox connects to the IP address it finds for
members.dyndns.org to register the current Firebox external
interface IP address with the DynDNS service.
The Firebox does not operate with other Dynamic DNS services,
only DynDNS.org.
