To display the Security function, the firewall option must be enabled in WAN Setup.

6.4.1 MAC Filtering

Each network device has a unique MAC address. You can block or forward the

packets based on the MAC addresses. The MAC Filtering Setup screen allows for

the setup of the MAC filtering policy and rules.

NOTE: This function is only available when in bridge mode. Instead of MAC

filtering, the other connection types use IP Filtering (pg. 62).

The policy FORWARDED means that all MAC layer frames will be FORWARDED

except those matching with any of the specified rules in the following table.

BLOCKED means that all MAC layer frames will be BLOCKED except those

matching with any of the specified rules in the following table. The default is

FORWARDED; this is changed by clicking the Change Policy button.

Choose Add or Remove to configure MAC filtering rules. The following screen

pops up when you click Add. Create a filter to identify the MAC layer frames by

specifying at least one condition below. If multiple conditions are specified, all of

them take effect. Click Save/Apply to save and activate the filter.
