Filters
The Wireless Array’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 168. Filters
User connections managed by the firewall are maintained statefully — once a user
flow is established through the Array, it is recognized and passed through
without application of all defined filtering rules. Stateful inspection runs
automatically on the Array. The rest of this section describes how to view and
manage filters.

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 426.
