AiProtection - DNS Filtering not working

Hi together,

I hope somebody can help me. Iam using an AC-87U with merlin 378.55. AiProtection - DNS Filtering is configured that all unknown devices should use the Norton Children DNS Server, Devices which I know and manually configure in AIProtection should use the Norton Safe DNS Server.

1.) Problem is:
that still all Devices are able to open all sites unfiltert.

AiProtection - DNS Filtering Config...
