MAC Filtering Setup
In some cases, you may want to manage Layer2 MAC address to block or permit a
computer within the home network. When you enable MAC filter rules, the DSL router
serves as a firewall that works at layer 2.
Note:
MAC filtering is only effective on ATM PVCs configured in bridge mode. If the ATM
PVCs are configured in other routing modes (such as PPPoE mode), the MAC
Filtering Setup page does not be configured.
Choose Security > MAC Filtering and the following page appears.
