What happens to open connections when a schedule change takes place?

    Good question!  Why not simply test it out and report back?

    My guess is that as long as the same TCP socket session is being used, it will stay up.  Only if a new DNS query (or connection?) is to be supplied, it may be blocked.

    Hello,

    That's a great question. Any open connections like streaming through Netflix would be unaffected. Only new, uncached DNS requests would be affected by the time-based filtering change. Typically, DNS caches in the browser are not cleared until exit so Netflix streams would continue past the time limit. 

    To impose a full network blackout, you may also configure some of NETGEAR's Advanced controls to disable networking completely (some models support full traffic stopping on a schedule that would stop Netflix at midnight). 

    If you have any questions or concerns, please don't hesitate to respond.

    Best regards,

    We bought our Netgear router because we read that it had great parental controls. This issue makes these controls (and thus this router) virtually worthless! Clearly not designed by anyone who has ever parented teenagers - who, as others have pointed ou,t will quickly figure out that if they are on Youtube at 10 PM they can stay on all night. Please fix this or else quit calling this Parental Control!

    "if they are on Youtube at 10 PM they can stay on all night."

    Was this what you understood from above?  LOL, this is "clearly" wrong understanding.  For each page or different object often a new DNS query and always a new HTTP connection (TCP socket) is opened which would be blocked then.  In terms of e.g YouTube that means that only the currently running video continues to play at the end - then this and everything else is blocked during the schedule.

    You can improve this while disabling the local resolver cache.

    Does this sound better?  Still going for "this issue makes these controls (and thus this router) virtually worthless! Clearly not designed by anyone who has ever parented teenagers"?  Whatever, simply test it out yourself.

    The time-based control feature has been developed entirely by NETGEAR, therefore please voice any suggestions or concerns regarding the time-based controls directly to NETGEAR. We are unable to deploy a fix or develop features for time-based controls because they have not been developed by OpenDNS. DNS requests may be cached locally on the computer for a period of time, and this includes youtube.com, and therefore the blocking may not apply exactly at 10pm.
