Configuring Packet Filters
Use the Filter Configuration panel, accessible from the Networking Services menu, to define packet

The panel contains the following tabs:
• Filter Table — View currently defined packet filters, and add or edit filters.
• Filter Stats — View counts of packets that match the filter criteria.
Filter Table
Choose Filter Configuration from the Networking Services menu to open the Filter Table tab
(Figure 89). By default, an incoming and outgoing filter is defined for each of the interfaces wlan0,
wlan1, and eth0. The Filter table displays the name of the interface, whether it is for incoming or
outgoing traffic, whether to accept or discard the packet, and the criteria used to accept or discard it.
