CHAPTER 9
Other Wireless Configuration
This chapter describes how to configure the Layer-2 Isolation and MAC Filter screens on
your ZyXEL Device.
9.1 Layer-2 Isolation Introduction
Layer-2 isolation is used to prevent wireless clients associated with your ZyXEL Device from
communicating with other wireless clients, APs, computers or routers in a network.
In the following example, layer-2 isolation is enabled on the ZyXEL Device (Z, in the figure)
to allow a guest wireless client (A) to access the main network router (B). The router provides
access to the Internet (C) and the network printer (D) 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.
" Intra-BSS Traffic Blocking is activated when you enable layer-2 isolation.
