2 Guest_SSID. This profile is intended for use by visitors and others who require
access to certain resources on the network (an Internet gateway or a network
printer, for example) but must not have access to the rest of the network. Layer 2
isolation is enabled (see Section on page 166), and QoS is set to NONE. Intra-
BSS traffic blocking is also enabled (see Section 9.4.1 on page 144). These fields
are all user-configurable.
1.2.6 Configuring Dual WLAN Adaptors
The NWA is equipped with dual wireless adaptors. This means you can configure
two different wireless networks to operate simultaneously.
In the following example, the NWA (Z) uses WLAN1 in Access Point mode to
allow IEEE 802.11b and IEEE 802.11g clients to access the wired network, and
WLAN2 in AP+Bridge mode to allow an IEEE 802.11a AP to communicate with
the wired network.

1.3 CAPWAP
The NWA supports CAPWAP (Control And Provisioning of Wireless Access Points).
This is ZyXEL’s implementation of the IETF’s (Internet Engineering Task Force)
CAPWAP protocol.
