Dynamic DNS

It allows Internet users to connect to your gateway using a static URL, rather than an IP Address. This is particularly useful because a dynamic IP address, by definition, is constantly changing making it difficult for internet users to find you.

The Service works as follows:

1.Obtain a free account for the service by registering at http://www.dyndns.org.

2.www.dyndns.org will automatically notify you confirming your account information.

3.Return to http://www.dyndns.org and use the "Create New Host" option to register your preferred Domain name. It is recommended that you register a name within the xxxx.dyndns.org hostname.

4.Details of your http://www.dyndns.org account (Name, password, Domain name) must then be entered and saved in the DDNS page of the TVP-221H. The TVP- 221H will then automatically notify DynDNS of your changing IP Address and DynDNS will in turn, map it to your registered Domain Name. Internet users will now be able to easily connect to your Virtual Servers (or DMZ PC) using your easy to remember Domain name.
