9.8 Dynamic DNS Setup
Tools > Dynamic DNS
Dynamic DNS (DDNS) is an Internet service that allows routers with varying public
IP addresses to be located using Internet domain names. To use DDNS, you must
setup an account with a DDNS provider such as DynDNS.org, D-Link DDNS, or
Oray.net.
Each configured WAN can have a different DDNS service if required. Once
configured, the router will update DDNS services changes in the WAN IP address so
that features that are dependent on accessing the router’s WAN via FQDN will be
directed to the correct IP address. When you set up an account with a DDNS service,
the host and domain name, username, password and wildcard support will be provided
by the account provider.
