Once you have the Dynamic DNS update URL, open your DD-WRT Control Panel. Navigate “Setup” >> “DDNS”. In the “Dynamic Domain Name System (DDNS)” section, please configure as follows:
DDNS Service: Custom
DYNDNS Server ipv4.cloudns.net
For “Username” and “Password” you must use your ClouDNS login credentials.
In the “Hostname” field you must type the hostname, for which the DDNS feature is activated.
