Step 5: Configure Dynamic DNS (If Needed)
If your network has a permanently assigned IP address, you can register a domain name and have 
that name linked with your IP address by public Domain Name Servers (DNS). However, if your 
Internet account uses a dynamically assigned IP address, you will not know in advance what your 
IP address will be, and the address can change frequently. In this case, you can use a commercial 
dynamic DNS 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.
which will allow you to register your domain to their IP address, and will forward traffic directed 
to your domain to your frequently-changing IP address. 
For rollover mode, you are going to need a fully qualified domain name 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 either for 
convenience or if you have a dynamic IP address.
The firewall contains a client that can connect to a dynamic DNS service provider. To use this 
feature, you must select a service provider and obtain an account with them. After you have 
configured your account information in the firewall, whenever your ISP-assigned IP address 
changes, your firewall will automatically contact your dynamic DNS service provider, log in to 
your account, and register your new IP address.
Perform the following steps to configure Dynamic DNS:
1.
If you haven’t already, log in to the firewall at its default LAN address of
 
with its default user name of 
admin
, default password of 
password
, or using whatever 
password and LAN address you have chosen for the firewall.
2.
From the Main Menu of the browser interface, under WAN Setup, click on Dynamic DNS. 
a.
Rollover Mode: You will get the screen shown in 
 with AUTO_ROLLOVER 
shown in the pulldown.
b.
Load Balancing Mode: Select WAN1 or WAN2 in the pulldown shown in 
 to 
invoke the appropriate WAN interface to program.
