I have a client machine (say A ) connectected to a linux router . I can browse internet without any problem . In router , i can configure MAC address filters . If i configure A's mac address should be disabled , A cannot access Router itself ? . Question : What exactly mac address filter mean ? disabling router access or disabling internet access ?
