Internet Features
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 VPN Gateway's DDNS screen (shown below).
4. The Broadband VPN Gateway will then automatically ensure that your current IP Address is recorded and updated 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, as shown on this
screen.
