Wireless-G VPN Broadband Router

The DDNS Tab

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other server behind the Router.

Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers, DynDNS.org or TZO.com.

DDNS

DDNS Service. If your DDNS service is provided by DynDNS.org, then select DynDNS.org in the drop-down menu. (See Figure 6-6.) If your DDNS service is provided by TZO, then select TZO.com. (See Figure 6-7.) The features available on the DDNS screen will vary, depending on which DDNS service provider you use.

•User Name, Password, and Host Name. Enter the User Name, Password, and Host Name of the account you set up with DynDNS.org.
