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.
