Dynamic DNS
If your network has a permanently assigned IP address, you can register a domain name that is linked to your IP address by public Domain Name Servers (DNS). More commonly, Internet accounts have dynamically assigned IP addresses in which the IP addresses change frequently. In this case, use a commercial Dynamic DNS service to register your domain to its IP address and forward traffic directed at your domain to your current IP address.
The wireless router has a client that can connect to a Dynamic DNS service provider. Once you set up Dynamic DNS in the wireless router, when your IP address changes, your wireless router contacts your Dynamic DNS service provider, logs in to your account, and registers your new IP address.
To set up Dynamic DNS:
1.Select Advanced > Dynamic DNS to display the following screen.
2.Access the website of one of the Dynamic DNS service providers whose names appear in the Service Provider
3.Select the Use a Dynamic DNS Service check box.
4.Select the name of your Dynamic DNS service provider.
5.Type the host name that your Dynamic DNS service provider gave you. This is sometimes called the domain name. If your URL is myName.dyndns.org, your host name is myName.
6.Type the user name for your Dynamic DNS account.
7.Type the password (or key) for your Dynamic DNS account.
8.Click Apply to save your settings.
If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the Dynamic DNS service does not work because private addresses are not routed on the Internet.
