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 http://192.168.1.1 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 Figure 4-8with AUTO_ROLLOVER shown in the pulldown.

b.Load Balancing Mode: Select WAN1 or WAN2 in the pulldown shown in Figure 4-8to invoke the appropriate WAN interface to program.
