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.
For security reasons it is desirable to block client to client communications for wireless clients associated with an Access Point (AP). It is also desirable to block client to client communications between clients associated with different AP’s on the local sub net. For instance an airport may have several AP’s to service several "hot spots" within the airport. However the client to client blocking feature of the AP will only block communications to other clients associated with the same AP. And will not block client to client of another AP communications. By using the Uplink Filtering function of the AP communications to all other clients of all other AP’s on the same sub net can be blocked.
It is important to note that this feature only works if all the AP’s are on the same sub net. If an AP is located on the far side of the gateway (i.e. on a different sub net) its clients will NOT be blocked from communicating with clients on the local sub net of interest.
This feature is accessed on the Filter Page of the user interface. Click on the Uplink Filter List link and add up to eight MAC addresses that WILL be allowed to communicate with clients of the AP. Make sure to include the MAC of the local DHCP server, if it not the same as the gateway as well as and redirect gateways and other servers that should be allowed to communicate with the AP’s wireless clients. Make sure to click on the save button on both the Uplink Filter List page as well as the Filter page to activate the function.
FILTERING BY ETHERNET PROTOCOL TYPE
Use the Ethernet Type Filter table to filter out Ethernet packet frames that match the Ethernet protocol type. Select Ethernet Type Filter Enable, then set the status of each Ethernet frame type in the list.
