Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It allows
Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP address, your
IP address may change whenever you connect, which makes it difficult to connect to you.
DDNS Services work as follows:
1. You must register for the service at one of the listed DDNS Service providers.
2. After registration, use the Service provider's normal procedure to obtain your desired
Domain name.
3. Enter your DDNS data on the Broadband ADSL Router's DDNS screen, and enable the
DDNS feature.
4. The Broadband ADSL Router will then automatically ensure that your current IP Address
is recorded at the DDNS service provider's Domain Name Server.
5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC)
using your Domain name, as shown on this screen.
