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 VPN firewall 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.
