9.6 Layer-2 Isolation List

Layer-2 isolation is used to prevent wireless clients associated with your NWA from communicating
with other wireless clients, APs, computers or routers in a network.
In the following example, layer-2 isolation is enabled on the NWA to allow a guest wireless client
(A) to access the main network router (B). The router provides access to the Internet and the
network printer (C) while preventing the client from accessing other computers and servers on the
network. The client can communicate with other wireless clients only if Intra-BSS Traffic blocking is
disabled.
Note: Intra-BSS Traffic Blocking is activated when you enable layer-2 isolation.
Figure 56 Layer-2 Isolation Application
MAC addresses that are not listed in the layer-2 isolation table are blocked from communicating
with the NWA's wireless clients except for broadcast packets. Layer-2 isolation does not check the
traffic between wireless clients that are associated with the same AP. Intra-BSS traffic allows
wireless clients associated with the same AP to communicate with each other.
This screen allows you to specify devices you want the users on your wireless networks to access.
