5.2 What You Need to Know
The following terms and concepts may help as you read through the chapter.
Rogue AP
Rogue APs are wireless access points operating in a network’s coverage area that are not under the
control of the network’s administrators, and can open up holes in a network’s security. See Chapter 11
on page 126 for details.
Friendly AP
Friendly APs are other wireless access points that are detected in your network, as well as any others that
you know are not a threat (those from neighboring networks, for example). See Chapter 11 on page 126
for details.

NWA/WAC.
The Internet Protocol (IP) address identifies a device on a network. Every networking device (including
computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
These networking devices are also known as hosts.
Figure 41 IP Setup
CHAPTER 6
Network
The figure above illustrates one possible setup of your NWA/WAC. The gateway IP address is 192.168.1.1
and the managed IP address of the NWA/WAC is 192.168.1.2 (default), but if the NWA/WAC is assigned
an IP address by a DHCP server, the default (192.168.1.2) will not be used. The gateway and the NWA/
WAC must belong in the same IP subnet to be able to communicate with each other.
6.1.1 Management Mode
This discusses using the NWA/WAC in management mode, which determines whether the NWA/WAC is
used in its standalone mode, or as part of a Control And Provisioning of Wireless Access Points (CAPWAP)
network.
About CAPWAP
The NWA/WAC supports CAPWAP. This is Zyxel’s implementation of the CAPWAP protocol (RFC 5415).
The CAPWAP data flow is protected by Datagram Transport Layer Security (DTLS).
The following figure illustrates a CAPWAP wireless network. You (U) configure the AP controller (C), which
then automatically updates the configurations of the managed APs (M1 ~ M4).
NWA / WAC Series User’s Guide

Chapter 6 Network
Figure 42 CAPWAP Network Example
Note: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP.
CAPWAP Discovery and Management
The link between CAPWAP-enabled access points proceeds as follows:
1An AP in managed AP mode joins a wired network (receives a dynamic IP address).
2The AP sends out a discovery request, looking for a CAPWAP AP controller.
3If there is an AP controller on the network, it receives the discovery request. If the AP controller is in
Manual mode it adds the details of the AP to its Unmanaged Access Points list, and you decide which
available APs to manage. If the AP controller is in Always Accept mode, it automatically adds the AP to
its Managed Access Points list and provides the managed AP with default configuration information, as
well as securely transmitting the DTLS pre-shared key. The managed AP is ready for association with
wireless clients.
Managed AP Finds the Controller
A managed NWA/WAC can find the controller in one of the following ways:
• Manually specify the controller’s IP address in the Web Configurator’s AC (AP Controller) Discovery
screen.
• Get the controller’s IP address from a DHCP server with the controller’s IP address configured as
option 138.
• Get the controller’s IP address from a DNS server SRV (Service) record.
NWA / WAC Series User’s Guide
76
Chapter 6 Network
• Broadcasting to discover the controller within the broadcast domain.
Note: The AP controller needs to have a static IP address. If it is a DHCP client, set the DHCP
server to reserve an IP address for the AP controller.
CAPWAP and IP Subnets
By default, CAPWAP works only between devices with IP addresses in the same subnet.
However, you can configure CAPWAP to operate between devices with IP addresses in different
subnets by doing the following.
• Activate DHCP. Your network’s DHCP server must support option 138 defined in RFC 5415.
• Configure DHCP option 138 with the IP address of the CAPWAP AP controller on your network.
DHCP Option 138 allows the CAPWAP management request (from the AP in managed AP mode) to
reach the AP controller in a different subnet, as shown in the following figure.
Figure 43 CAPWAP and DHCP Option 138
Notes on CAPWAP
This section lists some additional features of Zyxel’s implementation of the CAPWAP protocol.
• When the AP controller uses its internal Remote Authentication Dial In User Service (RADIUS) server,
managed APs also use the AP controller’s authentication server to authenticate wireless clients.
• If a managed AP’s link to the AP controller is broken, the managed AP continues to use the wireless
settings with which it was last provided.

6.3 VLAN
This section discusses how to configure the NWA/WAC’s VLAN settings.
NWA / WAC Series User’s Guide

Chapter 6 Network
Figure 45 Management VLAN Setup
In the figure above, to access and manage the NWA/WAC from computer A, the NWA/WAC and
switch B’s ports to which computer A and the NWA/WAC are connected should be in the same VLAN.
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN
membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority.
The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to
process the frame across the network.
Use this screen to configure the VLAN settings for your NWA/WAC. To access this screen, click
Configuration > Network > VLAN.
The screen varies depending on whether the NWA/WAC has an extra Ethernet port (except the uplink
port).

6.4 AC (AP Controller) Discovery
This section discusses how to configure the NWA/WAC’s AC (AP Controller) Discovery settings. You can
have the NWA/WAC managed by an AP controller on your network. When you do this, the NWA/WAC
can be configured ONLY by the AP controller. See Section 6.1.1 on page 75 for more information on
management mode and AP Controller.
Note: The AC (AP Controller) Discovery settings are not available in all NWA/WACs. See
Section 1.1 on page 13 for more information.
If you want to return the NWA/WAC to standalone AP mode, you can do one of the two following
options:
• Press the Reset button.
• Check the AP controller for the NWA/WAC’s IP address and use FTP to upload the default
configuration file to the NWA/WAC. You can get the configuration file at conf/system-default.conf.
You must reboot the device after uploading the configuration file.
To access the Controller Discover screen, click Configuration > Network > AC Discovery.
