Dynamic DNS Setup
This chapter discusses how to configure your Prestige to use Dynamic DNS.

10.1 Dynamic DNS

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.
10.1.1 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.

10.2 Configuring Dynamic DNS
