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
Enabled
next
to the Uplink Port MAC Address Filtering 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.
