Dynamic DNS Setup
12.1
Overview
DNS
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and
vice versa. The DNS server is extremely important because without it, you must know the IP
address of a machine before you can access it.
In addition to the system DNS server(s), each WAN interface (service) is set to have its own static
or dynamic DNS server list. You can configure a DNS static route to forward DNS queries for certain
domain names through a specific WAN interface to its DNS server(s). The Device uses a system
DNS server (in the order you specify in the
Broadband
screen) to resolve domain names that do
not match any DNS routing entry. After the Device receives a DNS reply from a DNS server, it
creates a new entry for the resolved IP address in the routing table.
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.

What You Can Do in this Chapter
•
Use the
DNS Entry
screen to view, configure, or remove DNS routes (
Section 12.2 on page
183
).
•
Use the
Dynamic DNS
screen to enable DDNS and configure the DDNS settings on the Device
(
Section 12.3 on page 184
).
12.1.2
What You Need To Know
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.
