In the "Host Name" field, you have to enter the fully qualified name of your dynamic domain (e.g. If you have multiple host names registered at your DDNS service, you can enter them in the "Host Name" field using the "-a" option.
If you aren't registered, register one and setup (add) your dynamic domain name first.
Once you have the information, you should be able to set it up using DD-WRT.
Example: this URL is similar to dividing the one above: The "ip_server_name" option uses the Location and the URI.
If there is not a URI, use "/" The "ip_server_name" string using the server above should be: "--ip_server_name Note the space beteen the Location and URI.
The IP address option is used to specify an alternate source to get your IP.
Many websites have options to view your IP Address.
