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.
Dynamic DNS Screen
Select
Advanced
on the main menu, then

lecting them in the list and clicking the "Web Site" button.

Details of your DDNS account (Name, password, Domain name)
must then be entered and saved on this screen.
This device will then automatically ensure that your current IP
Address is recorded by the DDNS Service Provider. (You do
NOT need to use the "Client" program provided by some DDNS
Service providers.)
From the Internet, users will now be able to connect to your
Virtual Servers (or DMZ PC) using your Domain name.
DDNS Data
DDNS Service
Select the desired DDNS Service provider.
User Name
Enter your Username for the DDNS Service.
Password/Key
Enter your current password for the DDNS Service.
Domain Name
Enter the domain name allocated to you by the DDNS Service. If you
have more than one name, enter the name you wish to use.
DDNS Status
This message is returned by the DDNS Server
Normally, this message should be "Update successful"
If the message is "No host", this indicates the host name entered
was not allocated to you. You need to connect to DDNS Service
provider and correct this problem.
