Dynamic DNS update interval

[kermus]

Hey!

Is there any way to shorten the Dynamic DNS update time interval?
The firewall will update the IP DDNS server only once every 25 days but the service provider will drop the IP control out within 7 days.

Hello!

Maybe some variation of :

awk '{print "0.0.0.0|0" > FILENAME}' /cf/conf/dyndns*

...in a cron task?
