1.2.3.5 Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the P-330W and other UPnP enabled devices can
dynamically join a network, obtain an IP address and convey its capabilities to other devices
on the network.
1.2.3.6 PPPoE
PPPoE facilitates the interaction of a host with an Internet modem to achieve access to highspeed data networks via a familiar "dial-up networking" user interface.
1.2.3.7 PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of
data from a remote client to a private server, creating a Virtual Private Network (VPN) using a
TCP/IP-based network.
PPTP supports on-demand, multi-protocol and virtual private networking over public
networks, such as the Internet. The P-330W supports one PPTP server connection at any given
time.
1.2.3.8 Dynamic DNS Support
With Dynamic DNS (Domain Name System) support, you can have a static hostname alias for
a dynamic IP address, allowing the host to be more easily accessible from various locations on
the Internet. You must register for this service with a Dynamic DNS service provider.
Chapter 1 Getting to Know Your P-330W
22
ZyXEL P-330W User’s Guide
1.2.3.9 Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).
1.2.3.10 Port Forwarding
Use this feature to forward incoming service requests to a server on your local network. You
may enter a single port number or a range of port numbers to be forwarded, and the local IP
address of the desired server.

3.1 Wizard Setup Overview
The web configurator’s setup wizard helps you configure your device to access the Internet.
The second screen has five variations depending on what encapsulation type you use. Refer to
your ISP checklist in the Quick Start Guide to know what to enter in each field. Leave a field
blank if you don’t have that information.
The fifth wizard screen varies according to the type of encapsulation that you select in the
third wizard screen.
3.2 Wizard Setup: Screen 2
The P-330W offers five choices of encapsulation. They are DHCP Client, Static IP,
PPP over Ethernet, L2TP or PPTP.
3.2.1 DHCP Client
Choose DHCP Client when the WAN port is used as regular Ethernet and your ISP assigns
you an IP address via DHCP.
Figure 4 Wizard 2: DHCP Client Encapsulation
3.2.2 Static IP

3.2.3 PPPoE Encapsulation
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an
IETF (Internet Engineering Task Force) draft standard specifying how a host personal
computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to
achieve access to high-speed data networks.
For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for instance, Radius). For the user, PPPoE provides a login
and authentication method that the existing Microsoft Dial-Up Networking software can
activate, and therefore requires no new learning or procedures for Windows users.
31
Chapter 3 Wizard Setup
ZyXELP-330W User’s Guide
One of the benefits of PPPoE is the ability to let end users access one of multiple network
services, a function known as dynamic service selection. This enables the service provider to
easily create and offer new IP services for specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber’s site.
By implementing PPPoE directly on the P-330W (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the P-330W does that part
of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.
Refer to the appendix for more information on PPPoE.

and partition your physical network into logical networks.
41
Chapter 4 System Screens
ZyXEL P-330W User’s Guide
4.3.1 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the P330W as a DHCP server or disable it. When configured as a server, the P-330W provides the
TCP/IP configuration for the clients. If DHCP service is disabled, you must have another
DHCP server on your LAN, or else the computer must be manually configured.
4.3.2 IP Pool Setup
The P-330W is pre-configured with a pool of 33 IP addresses starting from 192.168.10.33 to
192.168.10.65. This configuration leaves 32 IP addresses (excluding the P-330W itself) in the
lower range for other server computers, for instance, servers for mail, FTP, TFTP, web, etc.,
that you may have.
4.3.3 System DNS Servers
Refer to the IP Address and Subnet Mask section in the Setup Wizard chapter.
4.3.4 LAN TCP/IP
The P-330W has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.
4.3.5 Factory LAN Defaults
The LAN parameters of the P-330W are preset in the factory with the following values:
• IP address of 192.168.10.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 33 client IP addresses starting from 192.168.10.33.
These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), read the embedded web configurator help regarding what fields need
to be configured.

The subnet mask specifies the network number portion of an IP address. Your P330W will automatically calculate the subnet mask based on the IP address that
you assign. Unless you are implementing subnetting, use the subnet mask
computed by the P-330W 255.255.255.0.
DHCP
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (computers) to obtain TCP/IP configuration at startup from a
server. Choose Server box selected unless your ISP instructs you to do
otherwise. Choose Disabled the P-330W acting as a DHCP server. When
configured as a server, the P-330W provides TCP/IP configuration for the clients.
If not, DHCP service is disabled and you must have another DHCP server on
your LAN, or else the computers must be manually configured. When set as a
server, fill in the following four fields.

5.1 Wireless LAN Overview
This section introduces the wireless LAN(WLAN) and some basic scenarios.
5.1.1 IBSS
An Independent Basic Service Set (IBSS), also called an Ad-hoc network, is the simplest
WLAN configuration. An IBSS is defined as two or more computers with wireless adapters
within range of each other that from an independent (wireless) network without the need of an
access point (AP).
Figure 19 IBSS (Ad-hoc) Wireless LAN
5.1.2 BSS
A Basic Service Set (BSS) exists when all communications between wireless stations or
between a wireless station and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled,
wireless station A and B can access the wired network and communicate with each other.
When Intra-BSS is disabled, wireless station A and B can still access the wired network but
cannot communicate with each other.
Chapter 5 Wireless
46
ZyXEL P-330W User’s Guide
Figure 20 Basic Service set
5.1.3 ESS
An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an
access point, with each access point connected together by a wired network. This wired
connection between APs is called a Distribution System (DS). An ESSID (ESS IDentification)
uniquely identifies each ESS. All access points and their associated wireless stations within
the same ESS must have the same ESSID in order to communicate.
47
Chapter 5 Wireless
ZyXEL P-330W User’s Guide
Figure 21 Extended Service Set
5.1.4 RTS/CTS
A hidden node occurs when two stations are within range of the same access point, but are not
within range of each other. The following figure illustrates a hidden node. Both stations (STA)
are within range of the access point (AP) or wireless gateway, but out-of-range of each other,
so they cannot “hear” each other, that is they do not know if the channel is currently being
used. Therefore, they are considered hidden from each other.
Figure 22 RTS/CTS
When station A sends data to the P-330W, it might not know that station B is already using the
channel. If these two stations send data at the same time, collisions may occur when both sets
of data arrive at the AP at the same time, resulting in a loss of messages for both stations.

5.4.1 Authentication
Three different methods can be used to authenticate wireless stations to the network: Open
System, Shared Key, and Auto. The following figure illustrates the steps involved.
Figure 25 WEP Authentication Steps
Open system authentication involves an unencrypted two-message procedure. A wireless
station sends an open system authentication request to the AP, which will then automatically
accept and connect the wireless station to the network. In effect, open system is not
authentication at all as any station can gain access to the network.
Shared key authentication involves a four-message procedure. A wireless station sends a
shared key authentication request to the AP, which will then reply with a challenge text
message. The wireless station must then use the AP’s default WEP key to encrypt the
challenge text and return it to the AP, which attempts to decrypt the message using the AP’s
default WEP key. If the decrypted message matches the challenge text, the wireless station is
authenticated.
51
Chapter 5 Wireless
ZyXEL P-330W User’s Guide
When your P-330W's authentication method is set to open system, it will only accept open
system authentication requests. The same is true for shared key authentication. However,
when it is set to auto authentication, the P-330W will accept either type of authentication
request and the P-330W will fall back to use open authentication if the shared key does not
match.
5.4.2 Preamble Type
A preamble is used to synchronize the transmission timing in your wireless network. There are
two preamble modes: Long and Short.
Short preamble takes less time to process and minimizes overhead, so it should be used in a
good wireless network environment when all wireless clients support it.
Select Long if you have a ‘noisy’ network or are unsure of what preamble mode your wireless
clients support as all IEEE 802.11b compliant wireless adapters must support long preamble.
However, not all wireless adapters support short preamble. Use long preamble if you are
unsure what preamble mode the wireless adapters support, to ensure interpretability between
the P-330W and the wireless stations and to provide more reliable communication in ‘noisy’
networks..
Note: The P-330W and the wireless stations MUST use the
same preamble mode in order to communicate.

Wireless security is vital to your network to protect wireless communication between wireless
stations, access points and the wired network.
The figure below shows the possible wireless security levels. EAP (Extensible Authentication
Protocol) is used for authentication and utilizes dynamic WEP key exchange. It requires
interaction with a RADIUS (Remote Authentication Dial-In User Service) server either on the

5.7.1 WEP Overview
WEP (Wired Equivalent Privacy) as specified in the IEEE 802.11 standard provides methods
for both data encryption and wireless station authentication.
5.7.2 Data Encryption
WEP provides a mechanism for encrypting data using encryption keys. Both the AP and the
wireless stations must use the same WEP key to encrypt and decrypt data. Your P-330W
allows you to configure up to four 64-bit or 128-bit WEP keys, but only one key can be
enabled at any one time.

5.7.4 Introduction to WPA
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification draft.
Key differences between WPA and WEP are user authentication and improved data
encryption.
5.7.4.1 User Authentication
WPA applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate
wireless clients using an external RADIUS database. See later in this chapter and the
appendices for more information on IEEE 802.1x, RADIUS and EAP. Your wireless client
will need to be able to support 802.1x authentication to use RADIUS authentication.
Therefore, if you don’t have an external RADIUS server you should use WPA-PSK (WPA Pre-Shared Key) that only requires a single (identical) password entered into each access
point, wireless gateway and wireless client. As long as the passwords match, a client will be
granted access to a WLAN.
5.7.4.2 Encryption
WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message
Integrity Check (MIC) and IEEE 802.1x.
Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and
distributed by the authentication server. It includes a per-packet key mixing function, a
Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with
sequencing rules, and a re-keying mechanism.
TKIP regularly changes and rotates the encryption keys so that the same encryption key is
never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the
AP that then sets up a key hierarchy and management system, using the pair-wise key to
dynamically generate unique data encryption keys to encrypt every data packet that is
wirelessly communicated between the AP and the wireless clients. This all happens in the
background automatically.
The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data
packets, altering them and resending them. The MIC provides a strong mathematical function
in which the receiver and the transmitter each compute and then compare the MIC. If they do
not match, it is assumed that the data has been tampered with and the packet is dropped.
By generating unique data encryption keys for every data packet and by creating an integrity
checking mechanism (MIC), TKIP makes it much more difficult to decode data on a Wi-Fi
network than WEP, making it difficult for an intruder to break into the network.
The encryption mechanisms used for WPA and WPA-PSK are the same. The only difference
between the two is that WPA-PSK uses a simple common password, instead of user-specific
credentials. The common-password approach makes WPA-PSK susceptible to brute-force
password-guessing attacks but it’s still an improvement over WEP as it employs an easier-touse, consistent, single, alphanumeric password.
59
Chapter 5 Wireless
ZyXEL P-330W User’s Guide
5.7.4.3 WPA-PSK Application Example
A WPA-PSK application looks as follows.
1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key
(PSK) must consist of between 8 and 63 ASCII characters (including spaces and
symbols).
2 The AP checks each client’s password and (only) allows it to join the network if it
matches its password.
3 The AP derives and distributes keys to the wireless clients.
4 The AP and wireless clients use the TKIP encryption process to encrypt data exchanged
between them.
Figure 32 WPA - PSK Authentication
5.7.5 Introduction to WPA2
WPA2 is based on the same 802.11i spec as WPA. The primary difference between WPA and
WPA2 is that WPA2 uses AES encryption in places of TKIP. Like WPA, WPA2 can function
either using a pre-shared key or by using a RADIUS server to perform authentication. WPA2
also offers a mixed mode which allows WPA clients to authenticate and use TKIP encryption
while still allowing WPA2 clients to use AES. Configuration of WPA2 is the same as WPA.
5.7.6 Configuring WPA-PSK Authentication
In order to configure and enable WPA-PSK encryption; click the SECURITY link under
WIRELESS to display the Wireless Security screen. Select WPA (TKIP) from the

ZyXEL P-330W User’s Guide
5.7.7 Introduction to RADIUS
RADIUS is based on a client-sever model that supports authentication and accounting, where
access point is the client and the server is the RADIUS server. The RADIUS server handles
the following tasks among others:
• Authentication
Determines the identity of the users.
• Accounting
Keeps track of the client’s network activity.
RADIUS user is a simple package exchange in which your P-330W acts as a message relay
between the wireless station and the network RADIUS server.
5.7.7.1 Types of RADIUS Messages
The following types of RADIUS messages are exchanged between the access point and the
RADIUS server for user authentication:
• Access-Request
Sent by an access point requesting authentication.
• Access-Reject
Sent by a RADIUS server rejecting access.
• Access-Accept
Sent by a RADIUS server allowing access.
5.7.7.2 Access-Challenge
Sent by a RADIUS server requesting more information in order to allow access. The access
point sends a proper response from the user and then sends another Access-Request message.
The following types of RADIUS messages are exchanged between the access point and the
RADIUS server for user accounting:
5.7.7.3 Accounting-Request
Sent by the access point requesting accounting.
5.7.7.4 Accounting-Response
Sent by the RADIUS server to indicate that it has started or stopped accounting.
Chapter 5 Wireless
62
ZyXEL P-330W User’s Guide
In order to ensure network security, the access point and the RADIUS server use a shared
secret key, which is a password, they both know. The key is not sent over the network. In
addition to the shared key, password information exchanged is also encrypted to protect the
wired network from unauthorized access.
5.7.7.5 EAP Authentication Overview
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the
IEEE802.1x transport mechanism in order to support multiple types of user authentication. By
using EAP to interact with an EAP-compatible RADIUS server, the access point helps a
wireless station and a RADIUS server perform authentication.
The type of authentication you use depends on the RADIUS server or the AP. The P-330W
supports EAP-TLS, EAP-TTLS and PEAP with RADIUS. Refer to the Types of EAP
Authentication appendix for descriptions on the four common types.
Your P-330W supports EAP-MD5 (Message-Digest Algorithm 5) with RADIUS.
The following figure shows an overview of authentication when you specify a RADIUS server
on your access point.
Figure 34 EAP Authentication
The details below provide a general description of how IEEE 802.1x EAP authentication
works. For an example list of EAP-MD5 authentication steps, see the IEEE 802.1x appendix.
1 The wireless station sends a “start” message to the P-330W.
2 The P-330W sends a “request identity” message to the wireless station for identity
information.
3 The wireless station replies with identity information, including username and password.
4 The RADIUS server checks the user information against its user profile database and
determines whether or not to authenticate the wireless station.
5.7.7.6 WPA with RADIUS Application Example
You need the IP address of the RADIUS server, its port number (default is 1812), and the
RADIUS shared secret. A WPA application example with an external RADIUS server looks
as follows. “A” is the RADIUS server. “DS” is the distribution system.
1 The AP passes the wireless client’s authentication request to the RADIUS server.
63
Chapter 5 Wireless
ZyXEL P-330W User’s Guide
2 The RADIUS server then checks the user's identification against its database and grants
or denies network access accordingly.
3 The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then
sets up a key hierarchy and management system, using the pair-wise key to dynamically
generate unique data encryption keys to encrypt every data packet that is wirelessly
communicated between the AP and the wireless clients.

The Trusted Stations screen allows you to configure the P-330W to give exclusive access to up
to 20 devices. 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 the devices to configure
this screen.

whole inside network appear as a single computer to the outside world.
73
Chapter 6 Advanced Options
ZyXEL P-330W User’s Guide
You may enter a single port number or a range of port numbers to be forwarded, and the local
IP address of the desired server. The port number identifies a service; for example, web
service is on port 80 and FTP on port 21. In some cases, such as for unknown services or
where one server can support more than one service (for example both FTP and web service),
it might be better to specify a range of port numbers. You can allocate a server IP address that
corresponds to a port or a range of ports.
Many residential broadband ISP accounts do not allow you to run any server processes (such
as a Web or FTP server) from your location. Your ISP may periodically check for servers and
may suspend your account if it discovers any active services at your location. If you are
unsure, refer to your ISP.
The most often used port numbers are shown in the following table. Please refer to RFC 1700
for further information about port numbers. .

6.7.3 PPPoE Encapsulation
The P-330W supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband
modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dialup connection using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for example Radius). PPPoE provides a login and
authentication method that the existing Microsoft Dial-Up Networking software can activate,
and therefore requires no new learning or procedures for Windows users.
One of the benefits of PPPoE is the ability to let you access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily
create and offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires
no specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the P-330W (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the P-330W does that part
of the task. Furthermore, with NAT, all of the LANs’ computers will have access.
The screen shown next is for PPPoE encapsulation.

PPPoE
PPPoE in Action
An ADSL modem bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from
your computer to an ATM PVC (Permanent Virtual Circuit) which connects to a DSL Access
Concentrator where the PPP session terminates (see the next figure). One PVC can support
any number of PPP sessions from your LAN. PPPoE provides access control and billing
functionality in a manner similar to dial-up services using PPP.
Benefits of PPPoE
PPPoE offers the following benefits:
• It provides you with a familiar dial-up networking (DUN) user interface.
• It lessens the burden on the carriers of provisioning virtual circuits all the way to the ISP
on multiple switches for thousands of users. For GSTN (PSTN and ISDN), the switching
fabric is already in place.
• It allows the ISP to use the existing dial-up model to authenticate and (optionally) to
provide differentiated services.
Traditional Dial-up Scenario
The following diagram depicts a typical hardware configuration where the computers use
traditional dial-up networking.
Appendix A PPPoE
100
ZyXEL P-330W User’s Guide
Figure 65 Single-Computer per Router Hardware Configuration
How PPPoE Works
The PPPoE driver makes the Ethernet appear as a serial link to the computer and the computer
runs PPP over it, while the modem bridges the Ethernet frames to the Access Concentrator
(AC). Between the AC and an ISP, the AC is acting as a L2TP (Layer 2 Tunneling Protocol)
LAC (L2TP Access Concentrator) and tunnels the PPP frames to the ISP. The L2TP tunnel is
capable of carrying multiple PPP sessions.
With PPPoE, the VC (Virtual Circuit) is equivalent to the dial-up connection and is between
the modem and the AC, as opposed to all the way to the ISP. However, the PPP negotiation is
between the computer and the ISP.
P-330W as a PPPoE Client
When using the P-330W as a PPPoE client, the computers on the LAN see only Ethernet and
are not aware of PPPoE. This alleviates the administrator from having to manage the PPPoE
clients on the individual computers.

PPTP
What is PPTP?
PPTP (Point-to-Point Tunneling Protocol) is a Microsoft proprietary protocol (RFC 2637 for
PPTP is informational only) to tunnel PPP frames.
How can we transport PPP frames from a computer to a broadband
modem over Ethernet?
A solution is to build PPTP into the ANT (ADSL Network Termination) where PPTP is used
only over the short haul between the computer and the modem over Ethernet. For the rest of
the connection, the PPP frames are transported with PPP over AAL5 (RFC 2364) The PPP
connection, however, is still between the computer and the ISP. The various connections in
this setup are depicted in the following diagram. The drawback of this solution is that it
requires one separate ATM VC per destination.
Figure 67 Transport PPP frames over Ethernet
PPTP and the P-330W
When the P-330W is deployed in such a setup, it appears as a computer to the ANT.
In Windows VPN or PPTP Pass-Through feature, the PPTP tunneling is created from
Windows 95, 98 and NT clients to an NT server in a remote location. The pass-through feature
allows users on the network to access a different remote server using the P-330W's Internet
connection. In SUA/NAT mode, the P-330W is able to pass the PPTP packets to the internal
PPTP server (i.e. NT server) behind the NAT. You need to configure port forwarding for port
1723 to have the P-330W forward PPTP packets to the server. In the case above as the remote
PPTP Client initializes the PPTP connection, the user must configure the PPTP clients. The P330W initializes the PPTP connection hence; there is no need to configure the remote PPTP
clients.
Appendix B PPTP

ZyXEL P-330W User’s Guide
PPTP Protocol Overview
PPTP is very similar to L2TP, since L2TP is based on both PPTP and L2F (Cisco’s Layer 2
Forwarding). Conceptually, there are three parties in PPTP, namely the PNS (PPTP Network
Server), the PAC (PPTP Access Concentrator) and the PPTP user. The PNS is the box that
hosts both the PPP and the PPTP stacks and forms one end of the PPTP tunnel. The PAC is the
box that dials/answers the phone calls and relays the PPP frames to the PNS. The PPTP user is
not necessarily a PPP client (can be a PPP server too). Both the PNS and the PAC must have IP
connectivity; however, the PAC must in addition have dial-up capability. The phone call is
between the user and the PAC and the PAC tunnels the PPP frames to the PNS. The PPTP user
is unaware of the tunnel between the PAC and the PNS.
Figure 68 PPTP Protocol Overview
Microsoft includes PPTP as a part of the Windows OS. In Microsoft’s implementation, the
computer, and hence the P-330W, is the PNS that requests the PAC (the ANT) to place an
outgoing call over AAL5 to an RFC 2364 server.
Control & PPP Connections
Each PPTP session has distinct control connection and PPP data connection.
Call Connection
The control connection runs over TCP. Similar to L2TP, a tunnel control connection is first
established before call control messages can be exchanged. Please note that a tunnel control
connection supports multiple call sessions.
The following diagram depicts the message exchange of a successful call setup between a
computer and an ANT.
103
Appendix B PPTP
ZyXEL P-330W User’s Guide
Figure 69 Example Message Exchange between Computer and an ANT
PPP Data Connection
The PPP frames are tunneled between the PNS and PAC over GRE (General Routing
Encapsulation, RFC 1701, 1702). The individual calls within a tunnel are distinguished using
the Call ID field in the GRE header.

Wireless LAN and IEEE 802.11
A wireless LAN (WLAN) provides a flexible data communications system that you can use to
access various services (navigating the Internet, email, printer services, etc.) without the use of
a cabled connection. In effect a wireless LAN environment provides you the freedom to stay
connected to the network while roaming around in the coverage area.
Benefits of a Wireless LAN
Wireless LAN offers the following benefits:
• It provides you with access to network services in areas otherwise hard or expensive to
wire, such as historical buildings, buildings with asbestos materials and classrooms.
• It provides healthcare workers like doctors and nurses access to a complete patient’s
profile on a handheld or notebook computer upon entering a patient’s room.
• It allows flexible workgroups a lower total cost of ownership for workspaces that are
frequently reconfigured.
• It allows conference room users access to the network as they move from meeting to
meeting, getting up-to-date access to information and the ability to communicate
decisions while “on the go”.
• It provides campus-wide networking mobility, allowing enterprises the roaming
capability to set up easy-to-use wireless networks that cover the entire campus
transparently.
IEEE 802.11
The 1997 completion of the IEEE 802.11 standard for wireless LANs (WLANs) was a first
important step in the evolutionary development of wireless networking technologies. The
standard was developed to maximize interoperability between differing brands of wireless
LANs as well as to introduce a variety of performance improvements and benefits.
The IEEE 802.11 specifies three different transmission methods for the PHY, the layer
responsible for transferring data between nodes. Two of the methods use spread spectrum RF
signals, Direct Sequence Spread Spectrum (DSSS) and Frequency-Hopping Spread Spectrum
(FHSS), in the 2.4 to 2.4825 GHz unlicensed ISM (Industrial, Scientific and Medical) band.
The third method is infrared technology, using very high frequencies, just below visible light
in the electromagnetic spectrum to carry data.
Appendix D Wireless LAN and IEEE 802.11

ZyXEL P-330W User’s Guide
Ad-hoc Wireless LAN Configuration
The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of
computers with wireless nodes or stations (STA), which is called a Basic Service Set (BSS). In
the most basic form, a wireless LAN connects a set of computers with wireless adapters. Any
time two or more wireless adapters are within range of each other, they can set up an
independent network, which is commonly referred to as an Ad-hoc network or Independent
Basic Service Set (IBSS). The following diagram shows an example of notebook computers
using wireless adapters to form an Ad-hoc wireless LAN.
Figure 83 Peer-to-Peer Communication in an Ad-hoc Network
Infrastructure Wireless LAN Configuration
For Infrastructure WLANs, multiple Access Points (APs) link the WLAN to the wired
network and allow users to efficiently share network resources. The Access Points not only
provide communication with the wired network but also mediate wireless network traffic in
the immediate neighborhood. Multiple Access Points can provide wireless coverage for an
entire building or campus. All communications between stations or between a station and a
wired network client go through the Access Point.
The Extended Service Set (ESS) shown in the next figure consists of a series of overlapping
BSSs (each containing an Access Point) connected together by means of a Distribution System
(DS). Although the DS could be any type of network, it is almost invariably an Ethernet LAN.
Mobile nodes can roam between Access Points and seamless campus-wide coverage is
possible.

Wireless LAN With IEEE 802.1x
As wireless networks become popular for both portable computing and corporate networks,
security is now a priority.
Security Flaws with IEEE 802.11
Wireless networks based on the original IEEE 802.11 have a poor reputation for safety. The
IEEE 802.11b wireless access standard, first published in 1999, was based on the MAC
address. As the MAC address is sent across the wireless link in clear text, it is easy to spoof
and fake. Even the WEP (Wire Equivalent Privacy) data encryption is unreliable as it can be
easily decrypted with current computer speed
Deployment Issues with IEEE 802.11
User account management has become a network administrator’s nightmare in a corporate
environment, as the IEEE 802.11b standard does not provide any central user account
management. User access control is done through manual modification of the MAC address
table on the access point. Although WEP data encryption offers a form of data security, you
have to reset the WEP key on the clients each time you change your WEP key on the access
point.
IEEE 802.1x
In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to
support extended authentication as well as providing additional accounting and control
features. It is supported by Windows XP and a number of network devices.
Advantages of the IEEE 802.1x
• User based identification that allows for roaming.
• Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for
centralized user profile and accounting management on a network RADIUS server.
• Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional
authentication methods to be deployed with no changes to the access point or the wireless
clients.

ZyXEL P-330W User’s Guide
Appendix F
Types of EAP Authentication
This appendix discusses the five popular EAP authentication types: EAP-MD5, EAP-TLS,
EAP-TTLS, PEAP and LEAP.
The type of authentication you use depends on the RADIUS server or the AP. Consult your
network administrator for more information.
EAP-MD5 (Message-Digest Algorithm 5)
MD5 authentication is the simplest one-way authentication method. The authentication server
sends a challenge to the wireless station. The wireless station ‘proves’ that it knows the
password by encrypting the password with the challenge and sends back the information.
Password is not sent in plain text.
However, MD5 authentication has some weaknesses. Since the authentication server needs to
get the plaintext passwords, the passwords must be stored. Thus someone other than the
authentication server may access the password file. In addition, it is possible to impersonate an
authentication server as MD5 authentication method does not perform mutual authentication.
Finally, MD5 authentication method does not support data encryption with dynamic session
key. You must configure WEP encryption keys for data encryption.
EAP-TLS (Transport Layer Security)
With EAP-TLS, digital certifications are needed by both the server and the wireless stations
for mutual authentication. The server presents a certificate to the client. After validating the
identity of the server, the client sends a different certificate to the server. The exchange of
certificates is done in the open before a secured tunnel is created. This makes user identity
vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the
sender’s identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to
handle certificates, which imposes a management overhead.
EAP-TTLS (Tunneled Transport Layer Service)
EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the
server-side authentications to establish a secure connection. Client authentication is then done
by sending username and password through the secure connection, thus client identity is
protected. For client authentication, EAP-TTLS supports EAP methods and legacy
authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2.
Appendix F Types of EAP Authentication
124
ZyXEL P-330W User’s Guide
PEAP (Protected EAP)
Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection,
then use simple username and password methods through the secured connection to
authenticate the clients, thus hiding client identity. However, PEAP only supports EAP
methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card),
for client authentication. EAP-GTC is implemented only by Cisco.

signal to the antenna, which propagates the signal through the air. The antenna also operates in
reverse by capturing RF signals from the air.
Choosing the right antennas and positioning them properly increases the range and coverage
area of a wireless LAN.
Antenna Characteristics
Frequency
An antenna in the frequency of 2.4GHz (IEEE 802.11b) or 5GHz(IEEE 802.11a) is needed to
communicate efficiently in a wireless LAN.
Radiation Pattern
A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s
coverage area.
Antenna Gain
Antenna gain, measured in dB (decibel), is the increase in coverage within the RF beam width.
Higher antenna gain improves the range of the signal for better communications.
For an indoor site, each 1 dB increase in antenna gain results in a range increase of
approximately 2.5%. For an unobstructed outdoor site, each 1dB increase in gain results in a
range increase of approximately 5%. Actual results may vary depending on the network
environment.
Antenna gain is sometimes specified in dBi, which is how much the antenna increases the
signal power compared to using an isotropic antenna. An isotropic antenna is a theoretical
perfect antenna that sends out radio signals equally well in all directions. dBi represents the
true gain that the antenna provides.
Types of Antennas For WLAN
There are two types of antennas used for wireless LAN applications.
Appendix G Antenna Selection and Positioning Recommendation

ZyXEL P-330W User’s Guide
• Omni-directional antennas send the RF signal out in all directions on a horizontal plane.
The coverage area is torus-shaped (like a donut) which makes these antennas ideal for a
room environment. With a wide coverage area, it is possible to make circular overlapping
coverage areas with multiple access points.
• Directional antennas concentrate the RF signal in a beam, like a flashlight. The angle of
the beam width determines the direction of the coverage pattern; typically ranges from 20
degrees (less directional) to 90 degrees (very directional). The directional antennas are
ideal for hallways and outdoor point-to-point applications.
Positioning Antennas
In general, antennas should be mounted as high as practically possible and free of
obstructions. In point-to –point application, position both transmitting and receiving antenna
at the same height and in a direct line of sight to each other to attend the best performance.
For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For
omni-directional antennas mounted on a wall or ceiling, point the antenna down. For a single
AP application, place omni-directional antennas as close to the center of the coverage area as
possible.
For directional antennas, point the antenna in the direction of the desired coverage area.

Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but
changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it.
By contrast, the GNU General Public License is intended to guarantee your freedom to share
and change free software--to make sure the software is free for all its users. This General
Public License applies to most of the Free Software Foundation's software and to any other
program whose authors commit to using it. (Some other Free Software Foundation software is
covered by the GNU Library General Public License instead.) You can apply it to your
programs, too.
Appendix H Open Saftware Announcements

ZyXEL P-330W User’s Guide
When we speak of free software, we are referring to freedom, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free
software (and charge for this service if you wish), that you receive source code or can get it if
you want it, that you can change the software or use pieces of it in new free programs; and that
you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights
or to ask you to surrender the rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the software, or if you modify it. For example, if you distribute
copies of such a program, whether gratis or for a fee, you must give the recipients all the rights
that you have. You must make sure that they, too, receive or can get the source code. And you
must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license
which gives you legal permission to copy, distribute and/or modify the software. Also, for
each author's protection and ours, we want to make certain that everyone understands that
there is no warranty for this free software. If the software is modified by someone else and
passed on, we want its recipients to know that what they have is not the original, so that any
problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the
danger that redistributors of a free program will individually obtain patent licenses, in effect
making the program proprietary. To prevent this, we have made it clear that any patent must
be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the
copyright holder saying it may be distributed under the terms of this General Public License.
The "Program", below, refers to any such program or work, and a "work based on the
Program" means either the Program or any derivative work under copyright law: that is to say,
a work containing the Program or a portion of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter, translation is included without limitation in the
term "modification".) Each licensee is addressed as "you". Activities other than copying,
distribution and modification are not covered by this License; they are outside its scope. The
act of running the Program is not restricted, and the output from the Program is covered only if
its contents constitute a work based on the Program (independent of having been made by
running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive
it, in any medium, provided that you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to
this License and to the absence of any warranty; and give any other recipients of the Program a
copy of this License along with the Program. You may charge a fee for the physical act of
transferring a copy, and you may at your option offer warranty protection in exchange for a
fee.
131
Appendix H Open Saftware Announcements
ZyXEL P-330W User’s Guide
2. You may modify your copy or copies of the Program or any portion of it, thus forming a
work based on the Program, and copy and distribute such modifications or work under the
terms of Section 1 above, provided that you also meet all of these conditions:
a.) You must cause the modified files to carry prominent notices stating that you changed
the files and the date of any change.
b.) You must cause any work that you distribute or publish, that in whole or in part contains
or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all
third parties under the terms of this License.
c.) If the modified program normally reads commands interactively when run, you must cause it,
when started running for such interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice that there is no warranty (or else,
saying that you provide a warranty) and that users may redistribute the program under these conditions,
and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive
but does not normally print such an announcement, your work based on the Program is not
required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work
are not derived from the Program, and can be reasonably considered independent and separate
works in themselves, then this License, and its terms, do not apply to those sections when you
distribute them as separate works. But when you distribute the same sections as part of a whole
which is a work based on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the entire whole, and thus to
each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim
rights or contest your rights to work written entirely by you; rather, the intent is to exercise the
right to control the distribution of derivative or collective works based on the Program. In
addition, mere aggregation of another work not based on the Program with the Program (or
with a work based on the Program) on a volume of a storage or distribution medium does not
bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object
code or executable form under the terms of Sections 1 and 2 above provided that you also do
one of the following:
a.) Accompany it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a medium customarily used
for software interchange; or,
b.) Accompany it with a written offer, valid for at least three years, to give any third party,
for a charge no more than your cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange; or, c)
Accompany it with the information you received as to the offer to distribute corresponding
source code. (This alternative is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such an offer, in accord with
Subsection b above.) The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface definition files, plus the
Appendix H Open Saftware Announcements
132
ZyXEL P-330W User’s Guide
scripts used to control compilation and installation of the executable. However, as a special
exception, the source code distributed need not include anything that is normally distributed
(in either source or binary form) with the major components (compiler, kernel, and so on) of
the operating system on which the executable runs, unless that component itself accompanies
the executable. If distribution of executable or object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the source code from the
same place counts as distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly
provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute
the Program is void, and will automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this License will not have their
licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program
(or any work based on the Program), you indicate your acceptance of this License to do so, and all its
terms and conditions for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient
automatically receives a license from the original licensor to copy, distribute or modify the
Program subject to these terms and conditions. You may not impose any further restrictions on
the recipients' exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any
other reason (not limited to patent issues), conditions are imposed on you (whether by court
order, agreement or otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot distribute so as to satisfy
simultaneously your obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Program at all. For example, if a patent license
would not permit royalty-free redistribution of the Program by all those who receive copies
directly or indirectly through you, then the only way you could satisfy both it and this License
would be to refrain entirely from distribution of the Program. If any portion of this section is
held invalid or unenforceable under any particular circumstance, the balance of the section is
intended to apply and the section as a whole is intended to apply in other circumstances. It is
not the purpose of this section to induce you to infringe any patents or other property right
claims or to contest validity of any such claims; this section has the sole purpose of protecting
the integrity of the free software distribution system, which is implemented by public license
practices. Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that system; it is up to
the author/donor to decide if he or she is willing to distribute software through any other
system and a licensee cannot impose that choice. This section is intended to make thoroughly
clear what is believed to be a consequence of the rest of this License.
133
Appendix H Open Saftware Announcements
ZyXEL P-330W User’s Guide
8. If the distribution and/or use of the Program is restricted in certain countries either by
patents or by copyrighted interfaces, the original copyright holder who places the Program
under this License may add an explicit geographical distribution limitation excluding those
countries, so that distribution is permitted only in or among countries not thus excluded. In
such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General
Public License from time to time. Such new versions will be similar in spirit to the present
version, but may differ in detail to address new problems or concerns. Each version is given a
distinguishing version number. If the Program specifies a version number of this License
which applies to it and "any later version", you have the option of following the terms and
conditions either of that version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of this License, you may choose
any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution
conditions are different, write to the author to ask for permission. For software which is copyrighted by
the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of
our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING
BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO
OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY
HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND
CONDITIONS. All other trademarks or trade names mentioned herein, if any, are the property of their
respective owners.
