Filtering
The Access Point’s Packet Filtering features help control the amount of traffic exchanged between the wired and wireless
networks. There are four sub-tabs under the Filtering heading:
• Ethernet Protocol
• Static MAC
• Advanced
• TCP/UDP Port
Ethernet Protocol
The Ethernet Protocol Filter blocks or forwards packets based on the Ethernet protocols they support.
Follow these steps to configure the Ethernet Protocol Filter:
1. Select the interface or interfaces that will implement the filter from the Ethernet Protocol Filtering drop-down menu.
• Ethernet: Packets are examined at the Ethernet interface
• Wireless-Slot A or Wireless-Slot B: Packets are examined at the Wireless A or B interfaces
• All Interfaces: Packets are examined at both interfaces
• Disabled: The filter is not used
2. Select the Filter Operation Type.
• If set to Passthru, only the enabled Ethernet Protocols listed in the Filter Table will pass through the bridge.
• If set to Block, the bridge will block enabled Ethernet Protocols listed in the Filter Table.

3. Configure the Ethernet Protocol Filter Table. This table is pre-populated with existing Ethernet Protocol Filters,
however, you may enter additional filters by specifying the appropriate parameters.
