If your router's configuration is accessible from a web browser, try accessing it by logging into the local IP address of your router (for example, or ) and look for the Dynamic DNS (DDNS) settings. Each Dynamic DNS service may work better with a particular utility.
You will also be prompted for the username/password your registered with your Dynamic DNS service.
Lastly, you will be asked which ethernet port you primarily use to connect to the Internet (eth0 for wired or wlan0 for wireless, usually).
