Configuring MAC Address Filtering to Permit or Block Traffic
MAC Address Filtering permits and blocks network access from specific devices
through the use of MAC address list. The MAC Address Filtering settings apply for
all traffic except Intra-VLAN and Intra-SSID.
STEP 1 Click Firewall > MAC Filtering > MAC Address Filtering.
The MAC Address Filtering window opens.
STEP 2 Click On to enable the MAC Address Filtering feature, or click Off to disable it.
STEP 3 If you enable MAC Address Filtering, choose one of the following options as the
MAC Address Filtering policy:
• Block MAC Addresses (and allow all others): The MAC addresses in the list
are blocked and all other MAC addresses not included in the list are
permitted.
• Allow MAC Addresses (and block all others): Only the MAC addresses in
the list are permitted and all other MAC addresses not included in the list are
blocked.
STEP 4 In the MAC Address Filtering Rules area, specify the list of MAC addresses. To
add a MAC address, click Add. To edit an entry, click the Edit (pencil) icon. To
delete an entry, click the Delete (x) icon. To delete multiple entries, check them and
click Delete.
For example, if you click Add, the MAC Address Filtering Rule - Add/Edit window
opens. Choose the MAC address object from the MAC Address drop-down list
and click OK. If the MAC address object that you want is not in the list, choose
Create a new address to create a new MAC address object. To maintain the MAC
address objects, go to the Networking > Address Management page. See
Address Management, page175.
