Parental Controls with Schedule
How to set in PFSense block specific sites with certain schedules?
Hope there will be an answer with my question.
You might consider separate vlans and put your kids device in 1 of the created vlans. Then set rules that shut down internet access at a certain time(schedule feature in pfsense), https://doc.pfsense.org/index.php/Firewall_Rule_Schedules
Then consider using Opendns parental control ips for that vlan interface: 220.127.116.11
18.104.22.168…see opendns website for more details: https://www.opendns.com/about/press-releases/introducing-familyshield-parental-controls-the-easiest-way-to-keep-kids-safe-online/
