IP address will be, and the address can change frequently—hence, the need for a commercial
DDNS service, which allows you to register an extension to its domain, and restores DNS requests
for the resulting FQDN to your frequently-changing IP address.
After you have configured your account information in the firewall, whenever your ISP-assigned
IP address changes, your firewall will automatically contact your DDNS service provider, log in to
your account, and register your new IP address.
•
For auto-rollover mode, you will need a fully qualified domain name (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 fully qualified domain name (FQDN) either for
convenience or if you have a dynamic IP address.
To configure Dynamic DNS:
1.
Select
Network Configuration
from the primary menu and
Dynamic DNS
from the sub-
menu. The
Dynamic DNS Configuration
screen will display.
The
WAN Mode
section displays 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.
Check the Dynamic DNS Service radio box you want to enable. The fields corresponding to
the selection you have chosen will be highlighted. Each DNS service provider requires its own
parameters.
3.
Access the Web site of one of the DDNS service providers and set up an account. A link to
each DDNS provider is opposite the DNS Configuration screen name.
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.
