MAC Filter
The MAC-address-based filtering allows forwarding and blocking traffic subject to the source and
destination MAC addresses.
!
MAC-address-based filtering is active only when the device is configured as a transparent
bridge (the Bridge mode).
On the Configuration tab, you can select the operating mode of the MAC filter. Select the Allow
value from the Action drop-down list to allow traffic affected by the rules from the MAC
addresses tab and block the other traffic. Select the Deny value from the drop-down list to block
only traffic affected by the rules from the MAC addresses tab.
