Dynamic DNS

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.

The Service works as follows:

1.

You must register for the service at one of the listed DDNS Service Providers.

2.

After registration, follow the service provider's procedure to request a Domain Name and

have it allocated to you.

3.

Enter your DDNS data on the Broadband Router's DDNS screen.

4.

The TW100-BRF114U will then automatically ensure that your current IP Address is

recorded at the DDNS server.

If the DDNS Service provides software to perform this "IP address update"; you should

disable the "Update" function, or not use the software at all.

5.

From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC)

using your Domain Name.
