At first, sorry for my English but I try to answer...
First, add your domain in Dynamic DNS Services menu in dynu.com portal.
The next step is to add service DDNS in your OpenWRT router system. I use OpenWRT with LuCI. In GUI, in Services/Dynamic DNS, I added new service named eg "dynu". In Basic Settings tab, in field named "DDNS Service Provider" you must choose "own" or "other" and in field "Custom address update" enter link "http://api.dynu.com/nic/update?username=[USERNAME]&password=[PASSWORD]". In field "Hostname/Domain" enter your domain name which you entered in dynu.com portal. Of course, fields username and password should be entered.
In Advanced settings tab, I set 1) IP address source=URL 2) URL to detect=http://checkip.dynu.com 3) Enter network=WAN. Other fields are optional.
With this configuration my router check and update IP address.
This configuration you can see in file /etc/config/ddns
This is a part of that file:
config service 'dynu'
option domain 'yourdomain.dynu.com'
option username 'your_name_in_dynu.com'
option interface 'wan'
option use_syslog '2'
option use_logfile '1'
option ip_source 'web'
option ip_url 'http://checkip.dynu.com'
option update_url 'http://api.dynu.com/nic/update?username=[USERNAME]&password=[PASSW
ORD]'
option password 'your_password_in_dynu.com'
option enabled '1'

I just changed the UPDATE URL for just one domain:
http://api.dynu.com/nic/update?hostname=mmmmxxx.com&password=PASSWORD

It worked. Thank you.
