Tried to block internet access for one of my iPhone for testing purpose (it has dummy SIM means no cellular data)

Enable Parental Controls (i.e it is ON)

Choose a specific home device that I want to block then choose option : "Always" ,,,,,,,,,,,,my router screenshot same as the link above

Click Apply

But it didn't work !!!!

Tried another iphone same issue

I have latest firmware and I did restart the router as well

Am I missing something ?

Practical troubleshooting note for (and for later readers): when a router “Apply” for parental controls appears to succeed but an iPhone still has internet, the root cause is usually one of a few repeatable configuration or protocol gaps rather than the phone itself. The checklist below targets the things routers commonly miss.

  • Verify which network the iPhone is actually on: Settings > Wi‑Fi > tap the (i). Confirm SSID, IPv4/IPv6 addresses and the device’s Wi‑Fi Address (MAC). If the phone is on a guest SSID or a different band, the rule may not apply.
  • Cross-check the MAC shown on the phone with the router’s client list. Modern iOS can use a Private/Randomized MAC per network; if enabled, disable the Private Address for that SSID or use the router’s current MAC to create a rule.
  • Check for IPv6 bypass: parental filters often cover only IPv4. If the iPhone has an IPv6 global address, either enable IPv6 filtering on the router or disable IPv6 while testing.
  • Test whether the router is only blocking DNS/content filtering: set the phone’s Wi‑Fi DNS temporarily to a public resolver (e.g., 8.8.8.8). If internet returns, the router was using DNS-only blocking.
  • Make the policy robust: reserve a DHCP IP for the phone’s MAC, then create a firewall deny rule for that IP to WAN (or use MAC-based blocking). Reconnect the phone so it gets the reserved lease.
  • Check router logs and apply/reboot sequence: some routers require a device DHCP renew or a router reboot before rules take effect. Also confirm router time and timezone if schedules are used.
  • If none of the above work, suspect a firmware/implementation bug: try a factory-default and reconfigure parental settings, test with a different router, or consult the vendor’s support/KB.

As noted, this question shows up a lot because the visible UI often hides these edge cases. The steps above cover the usual overlooked reasons and give practical fixes that work across most home routers.

You've asked this exact same question in at least three other forums, all on 18th August, and had responses with regard to the solution from all of them. Why are you asking it again here?
