Dynamic DNS Setup
11.1
Overview
Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic
DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). 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 will always be able to
call you even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for
people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name.
The Dynamic DNS service provider will give you a password or key.
11.1.1
What You Can Do in the DDNS Screen
Use the
Dynamic DNS
screen (
Section 11.2 on page 139
) to enable DDNS and configure the DDNS
settings on the Device.
11.1.2
What You Need To Know About DDNS
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 be able to use, for example,
www.yourhost.dyndns.org and still reach your hostname.
If you have a private WAN IP address, then you cannot use Dynamic DNS.
11.2
The Dynamic DNS Screen
Use this screen to change your Device’s DDNS. Click
Network Setting > Dynamic DNS
. The
screen appears as shown.
