5.5.2 MAC Filtering
NOTE: This option is only available in bridge mode. Other modes use IP Filtering
to perform a similar function.
Each network device has a unique 48-bit MAC address. This can be used to filter
(block or forward) packets based on the originating device. MAC filtering policy and
rules for the VR-3030 can be set according to the following procedure.
The MAC Filtering Global Policy is defined as follows. FORWARDED means that all
MAC layer frames will be FORWARDED except those matching the MAC filter rules.
BLOCKED means that all MAC layer frames will be BLOCKED except those
matching the MAC filter rules. The default MAC Filtering Global policy is
FORWARDED. It can be changed by clicking the Change Policy button.
