After you have configured your account information in the network storage, whenever your
ISP-assigned IP address changes, your network storage will automatically contact your
DDNS service provider, log in to your account, and register your new IP address.
You may need to use a fully qualified domain name (FQDN):
For auto-rollover mode, you will need a FQDN to implement features such as exposed
hosts and virtual private networks regardless of whether you have a fixed or dynamic IP
address.
For load balancing mode, you may still need a FQDN either for convenience or if you
have a dynamic IP address.
Note: If your ISP assigns a private WAN IP address such as 192.168.x.x
or 10.x.x.x, the dynamic DNS service will not work because private
addresses will not be routed on the Internet.
To configure dynamic DNS:
1. Select Network Configuration > Dynamic DNS from the menu and click the Dynamic
DNS Configuration tab. The Dynamic DNS Configuration screen is displayed.
The Current WAN Mode section reports the currently configured WAN mode. (For
example, Single Port WAN1, Load Balancing or Auto Rollover.) Only those options that
match the configured WAN Mode will be accessible.
2. Select the tab for the DDNS service provider you will use.
