Dynamic DNS

With Dynamic DNS, you can update your current dynamic IP address with one or

many dynamic DNS services so that anyone can contact you (as in NetMeeting or

CU-SeeMe). You can also access your FTP server or Web site on your own

computer using a domain name (for instance, myhost.dhs.org, where myhost is a

name of your choice) that will never change instead of using an IP address that

changes each time you reconnect. Your friends or relatives can always call you

even if they don't know your IP address.

First of all, you must register a dynamic DNS account with, for example

www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP

server that still wants a domain name. The Dynamic DNS service provider gives

you a password or key.

DYNDNS wildcard

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be

aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you

want to use, for example, www.yourhost.dyndns.org and still reach your host

name.

Configuring Dynamic DNS

To change the DDNS settings, click SYSTEM, then the DDNS tab. The screen

illustrated in Figure 18 appears.

Note: If you have a private WAN IP address, you cannot use Dynamic

DNS.
