SECURITY FILTERS

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.

CLIENT LIST TIMEOUT

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).

UPLINK PORT MAC ADDRESS FILTERING

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.
