You may try the following settings:

Service Type: dyndns
Server: api.dynu.com
Username: your Dynu account username
Password: your Dynu account password
Hostname: your Dynu hostname

Service Type: dyndns
Server: api.dynu.com
Username: **********
Password: **********
Hostname: *****.dynu.net

I've done already that, but nothing happens, router did not update ip address
