Every Globe subscriber, who applied for wired internet includes a free modem/router with Wi-Fi capable to connect your wireless devices like smartphones, tablets and laptops. In this MAC filtering tutorial we are using Prolink H5004NK model but this concept will also work on other router models (H5001NS). All you need to know is the idea on how your router firewall settings or configuration work, especially MAC Filter options.

How to block devices MAC address:

1. Connect to your router / Wi-Fi, open your browser then access the web UI by typing 192.168.254.254.
3. Go to Firewall tab, look for MAC filter options. Outgoing and Incoming Default Policy must be set to "Allow".
4. By default policy, settings are configured to allow all MAC address as there’s no rule listed on the filter table.

  • Direction: Outgoing
  • Action:  Deny
  • Source MAC: “input the MAC address you are trying to block without colon (:) e.g. 00E076510401”

Try to browse using the device with the MAC blocked on the Globe router, it shouldn’t connect to the internet.
