Chapter 3 Configuring the DOCSIS Residential Gateway
Setup Basic Settings - Save RG Configuration to Local PC Page
The following illustration is an example of the Setup Basic Settings - Save RG
Configuration to Local PC page.
To Save your current setting to your computer, click the floppy disk icon in the
lower portion of the screen. You will be prompted to provide a file name and
location for the backup configuration file.
To Restore your setting, click Browse and select the backup configuration file name
that you saved on your PC. The path and filename of the backup configuration
appears in the File Name field. Then, click Download to restore your configuration
file. A Download Success message appears when the restore is complete.
Configure Dynamic DNS
Use the Setup Advanced Settings - Dynamic DNS page to configure the Dynamic
Domain Name Service (DDNS). This service provides the residential gateway that
has a variable and frequently changing IP address with a well known host name
resolvable by network applications through standard DNS queries. If you have a
fixed IP address, you don't need to use DDNS. It is useful when you are hosting your
own website, FTP server, or other server behind the device. Before using this feature,
you need to sign up for DDNS service at a supported DDNS service provider.
