This document is specific to the Cortexa 7202 and previous models. New Cortexa hardware (2009) cannot use this method to update Dynamic DNS (DDNS) accounts. For new Cortexa hardware, DDNS accounts can be updated by some network routers or by other computers on the home network through update clients. The Cortexa 7202 supports several versions of dynamic DNS. The version explained here is DynDNS. This walk through assumes you have already created a DynDNS acount and host name.
