Change ddns update number of days

[spazio]

I use dynamic DNS.
If the ip doesn't change or 25 days have past. PFsense doesn't update the ddns provider.
The problem is some provider required more frequent update.
Is it possible to change the 25 days to let's say 10 days.

thanks for any input

I'm not aware of any provider that requires more frequent than that, which are you seeing where that's the case? Generally it's a month or more. That's hard coded in the source, /etc/inc/dyndns.class
