Dynamic Dns (Domain Name Server) - NETGEAR MR814V2 User Manual

From the Internet, ALL Virtual Servers have the IP
Address allocated by your ISP.
Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use
the Internet IP Address (the IP Address allocated to you by your ISP).
e.g.
http://203.70.212.52
ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic.
However, you can use the Dynamic DNS feature, described in the following section, to allow
users to connect to your Virtual Servers using a URL, rather than an IP Address.

Dynamic DNS (Domain Name Server)

This free service is very useful when combined with the Virtual Server feature. It allows Inte r-
net 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 wh enever you connect, which makes it difficult to connect to you.
The Service works as follows:
1. You must register for the service at http://www.dyndns.org (Registration is free). Your
password will be E-mailed to you.
2. After registration, use the "Create New Host" option (at www.dyndns.org) to request your
desired Domain name.
3. Enter your data from www.dyndns.org in the Wireless Router's DDNS screen.
4. The Wireless Router will then automatically ensure that your current IP Address is re-
corded at http://www.dyndns.org
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.
