Each type of bridge filter for each operating mode supports a different set of “forwarding actions.”
Your particular set up and device configuration will determine which type of filter and forwarding
arrangement will be the most useful. For our purposes, we will illustrate what we feel to be the
most commonly used filter arrangement: the Destination MAC Address Filter used in Unrestricted
Mode.

Consider the following situation: you know the destination of a packet, and you want to control its
forwarding action. With the use of filters, you can:
•
forwarding action. With the use of filters, you can:
•
specify a Device List for connection
•
specify a Device List for which you would discard the packet
•
specify a LAN or WAN for which you would discard the packet
•
specify a complete discard of the packet for the entire system
The following example illustrates how to configure a filter when you know the Destination MAC
Address. To configure filters in other situations, follow similar principles as you work your way
through the CFGEDIT screens. For details on the differences between filters and their forwarding
actions, refer to the discussion beginning on
