ECURITY ILTERS
These options allow you to block communication among wireless clients
(client-to-client blocking) and prevent wireless clients from performing access
point administration.
Ethernet Broadcast Storm Control—This option allows users to limit
broadcast/multicast traffic coming from the Ethernet network. This feature
allows wireless clients to communicate properly under a heavy broadcast
environment.
When enabled, the access point discards broadcast/multicast packets if the
broadcast rate exceeds 180 packets per second or 30KB of data per second.
Additionally, any single source of broadcast/multicast transmissions is limited
to five packets per second or 8KB of data per second.
Ethernet broadcast storm control improves wireless performance on networks
that have high broadcast data rates. However, if the network requires high
broadcast/multicast data rate transmissions (for example, a media streaming
server) this feature should be disabled.
Local Bridge Filter—Enable this filter to prevent direct communication
between wireless clients, creating a more secure wireless network.
AP Management Filter—Enable this filter to prevent wireless clients from
accessing the access point for management; for example through TELNET or
SNMP.

LIENT IST IMEOUT
This option sets the timeout for inactive clients to be disassociated and removed
from the associated client list. The interval can be set to 1, 5, 10, 30 or 60
minutes (default is 30 minutes).
U P MAC A
PLINK ORT
This feature allows associated wireless clients to communicate only with specific
selected MAC addresses on a sub net. By only allowing clients to communicate
with a few specific servers such as DHCP server, a Gateway, or a local web server,
clients are blocked from communicating with other clients on the local sub net,
but are still allowed (via the gateway) to communicate with severs on the
Internet.
Note: In most cases client to client blocking should also be enabled as the
Uplink Filter only works on packets coming into the AP from its Ethernet (uplink)
port.
