Wireless Access Point
Configuring the Wireless AP 389
Filters
The Wireless AP’s integrated firewall uses stateful inspection to speed the
decision of whether to allow or deny traffic. Filters are used to define the rules
used for blocking or passing traffic. Filters can also set the VLAN and QoS level
for selected traffic.
Filters may be used based on your experience with Application Control Windows
to eliminate or cap the amount of traffic allowed for less desirable applications.
Figure 188. Filters
User connections managed by the firewall are maintained statefully — once a user
flow is established through the AP, it is recognized and passed through without
application of all defined filtering rules. Stateful inspection runs automatically on
the AP. The rest of this section describes how to view and manage filters.
Filters are organized in groups, called Filter Lists. A filter list allows you to apply
a uniform set of filters to SSIDs or Groups very easily. Similarly, you can use a
custom Application Control list to create a set of applications that are handled as a
group for convenience when creating filters.
The read-only Filters window provides you with an overview of all filter lists and
Application Control lists that have been defined for this AP, and the filters that
have been created in each list. Filters are listed in the left side column by name
The air cleaner feature offers a number of predetermined filter rules that
eliminate a great deal of unnecessary wireless traffic. See “Air Cleaner” on
page 466.
