I have bee asked to set WiFi scheduling as part of parental control on a home network. Hence I have blocked internet access for 2 devices (Apple (iPad & iPhone) from 8pm thru 8am.
However, I have also been asked to block Facetime on these same 2 devices on the same scheduled basis. Although I have blocked internet access as described, Facetime is still accessible on both during the restricted time period.
The router is a Technicolour 582N from Plusnet (UK).
