For consumer router “parental” control, blocking, quotaing, monitoring, as far as I’m aware Gargoyle Router is the best option out there.
Based on DDWRT it allows you granular control for IP address, IP ranges, download quotas, time restriction and you can do a whole lot of different filtering/blocking.
Takes a little bit of time to work out the logic and to setup but a great tool if you’ve need to restrict or monitor those kids or flatmates 
Sadly it only runs on the AR150, MT300N, MT300N-V2 and AR750
