Parental controls on EA6300 work only occasionally

Hi All,

I have EA6300 behind of SmartRG 505n VDSL router, which operates in bridge mode.  I am connecting to Internet via PPPoE.  User name and password are entered in EA6300 settings.

Parental controls on EA6300 work sometimes work, sometimes do not.  Time zone should not be an issue, because things do not work even when I select to Always block a device.

Reboot of router couple of times fixed the problem, and parental controls started working, but it does not always help.

Did anyone have similar problems?  What is the solution?  Any help would be appreciated.

Thanks

Archie
