Configure Dynamic DNS

Dynamic DNS (DDNS) is an Internet service that allows devices with varying public IP addresses to be located using Internet domain names. To use DDNS, you need to set up an account with a DDNS provider such as DynDNS.org, TZO.com, Oray.net, or 3322.org. (Links to DynDNS, TZO, Oray, and 3322 are provided for your convenience as option arrows on the DDNS configuration screens.) The UTM firmware includes software that notifies DDNS servers of changes in the WAN IP address, so that the services running on this network can be accessed by others on the Internet.

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 do not know in advance what your 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 forwards DNS requests for the resulting fully qualified domain name (FQDN) to your frequently changing IP address.

After you have configured your account information on the UTM, when your ISP-assigned IP address changes, your UTM automatically contacts your DDNS service provider, logs in to your account, and registers your new IP address.

Consider the following:

•For auto-rollover mode, you need an 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 might still need an 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 DDNS service does not work because private addresses are not routed on the Internet.
