Set Up and Manage Dynamic DNS
Internet service providers (ISPs) assign numbers called IP addresses to identify each
Internet account. Most ISPs use dynamically assigned IP addresses. This means that the IP
address can change at any time. You can use the IP address to access your network
remotely, but most people do not know what their IP addresses are or when this number
To make it easier to connect, you can get a free account with a Dynamic DNS service that
lets you use a domain name to access your home network. To use this account, you must set
up the modem router to use Dynamic DNS. Then the modem router notifies the Dynamic
DNS service provider whenever its IP address changes. When you access your Dynamic
DNS account, the service finds the current IP address of your home network and
automatically connects you.
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.
Your Personal FTP Server
With a dynamic DNS account, you can use FTP to access your network when you are not
home through Dynamic DNS.
To set up your personal account and use FTP:
1. Register for an account with a supported Dynamic DNS service provider.
For more information, see Set Up Dynamic DNS on page 126.
2. Make sure that your Internet connection is working.
Your modem router must use a direct Internet connection. It cannot connect to a different
router to access the Internet.
3. Connect a USB storage device to the USB port of the modem router.
4. Set up FTP access in the modem router.
For more information, see Set Up FTP Access Through the Internet on page 127.
5. On a remote computer with Internet access, you can use FTP to access your modem router
