The PC is NOT blocked, even if the notification "Blocked-Daily time limit is reached" was received

Dear all,

even if I received a notification "Blocked - Daily time limit reached" the computer of my sons was not blocked.

 

May it caused because that computer is connected to internet via a Router?

In particular the Router receives a dynamic IP Address from ISP, instead the computer of my sons receive a FIXED IP address from the router.

If this is the reason why the PC is not blocked, how can I solve this problem ?

 

Do not hesitate to ask me further informations :)

 

Many Thanks in advance for your attention.

 

Regards,

Mauro.
