Chapter 12 Layer-2 Isolation Screen
NWA-3500/NWA-3550 User’s Guide
166
MAC addresses that are not listed in the Allow devices with these MAC
addresses table of the Wireless > Layer-2 Isolation screen 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.
12.2 What You Can Do in the Layer-2 Isolation
Screen
Use the Wireless > Layer-2 Isolation screen (see Section 12.4 on page 167) to
configure the MAC addresses of the wireless client, AP, computer or router that
you want to allow the associated wireless clients to have access to.
12.3 What You Need To Know
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address is assigned at the factory and consists of six pairs of hexadecimal
characters, for example, 00:A0:C5:00:00:02. You need to know the MAC address
of each device to configure MAC filtering on the NWA.
If layer-2 isolation is enabled, you need to know the MAC address of each wireless
client, AP, computer or router that you want to allow to communicate with the
ZyXEL Device's wireless clients.
