to your frequently changing IP address.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic

Your gateway contains a client that can connect to the Dynamic DNS service that
DynDNS.org provided. First visit their website at
account and host name that you configure in the gateway. Then, whenever your
ISP-assigned IP address changes, your gateway automatically contacts the Dynamic DNS

name is hostname, for example, you can reach your gateway at http://hostname.dyndns.org.
