CHAPTER 1
Getting to Know Your Router
1.1 Overview
This chapter introduces the main features and applications of the Router.
The Router upgrades the speed of your existing wireless network, providing faster network access
to mobile users. Making use of IEEE 802.11AC technology, it not only upgrades your network to the
next level but also eliminates dead spots, while offering backward compatibility with other IEEE
802.11b/g/n compatible devices.
A range of services such as a firewall and content filtering are also available for secure Internet
computing. You can use media bandwidth management to efficiently manage traffic on your
network. Bandwidth management features allow you to prioritize time-sensitive or highly important
applications such as Voice over the Internet (VoIP).
1.2 Applications
Your can create the following networks using the Router:
•Wired. You can connect network devices via the Ethernet ports of the Router so that they can
communicate with each other and access the Internet.
•Wireless. Wireless clients can connect to the Router to access network resources.
•WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the Router
Use any of the following methods to manage the Router.
• Web Configurator. This is recommended for everyday management of the Router using a
(supported) web browser.
• Wireless switch. You can use the built-in switch of the Router to turn the wireless function on and
off without opening the Web Configurator.
• WPS (Wi-Fi Protected Setup) button. You can use the WPS button or the WPS section of the Web
Configurator to set up a wireless network with your Router.
Chapter 1 Getting to Know Your Router
NBG6503 User’s Guide

1.4 Good Habits for Managing the Router
Do the following things regularly to make the Router more secure and to manage the Router more
effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the Router to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the Router. You
could simply restore your last configuration.

1.6 The WPS Button
Your Router supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless
network. WPS is an industry standard specification, defined by the WiFi Alliance.
WPS allows you to quickly set up a wireless network with strong security, without having to
configure security settings manually. Each WPS connection works between two devices. Both
devices must support WPS (check each device’s documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device
to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set
up a secure network by themselves.
For more information on using WPS, see Section 9.3 on page 73.
1.7 Wall Mounting
You may need screw anchors if mounting on a concrete or brick wall.
1Select a position free of obstructions on a wall strong enough to hold the weight of the
device.
2Mark two holes on the wall at the appropriate distance apart for the screws.
Be careful to avoid damaging pipes or cables located inside the wall
when drilling holes for the screws.
WLAN 2.4 GHz Green On The Router is ready, but is not sending/receiving data through
the wireless LAN 2.4 GHz band.
Blinking The Router is sending/receiving data through the wireless LAN
2.4 GHz band.
Off The wireless LAN 2.4 GHz band is not ready or has failed.
WPS Green On WPS is enabled.
Blinking The Router is negotiating a WPS connection with a wireless
client.
Off The wireless LAN is not ready or has failed.

3If using screw anchors, drill two holes for the screw anchors into the wall. Push the
anchors into the full depth of the holes, then insert the screws into the anchors. Do not
insert the screws all the way in - leave a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not
insert the screws all the way in - leave a gap of about 0.5 cm.
4Make sure the screws are fastened well enough to hold the weight of the Router with the
connection cables.
5Align the holes on the back of the Router with the screws on the wall. Hang the Router on
the screws.

2.3.3 Connection Type: PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) 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).
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 Router (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the Router does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.
Figure 8 Internet Connection Type: PPPoE
Subnet Mask Enter the IP subnet mask in this field.
Default
Gateway Enter the gateway IP address in this field.
Primary DNS DNS (Domain Name System) is for mapping a domain name to its corresponding IP address
and vice versa. The DNS server is extremely important because without it, you must know
the IP address of a computer before you can access it. The Router uses a system DNS
server (in the order you specify here) to resolve domain names for DDNS and the time

CHAPTER 9
Tutorials
9.1 Overview
This chapter provides tutorials for your Router as follows:
•Connecting to the Internet from an Access Point
•Configuring Wireless Security Using WPS
•Enabling and Configuring Wireless Security (No WPS)
•If your connection is successful, open your Internet browser and enter http://www.zyxel.com or
the URL of any other web site in the address bar. If you are able to access the web site, your
wireless connection is successfully configured.
9.2 Connecting to the Internet from an Access Point
This section gives you an example of how to set up an access point (AP) and wireless client (a
notebook (B), in this example) for wireless communication. B can access the Internet through the
access point wirelessly.
Figure 50 Wireless Access Point Connection to the Internet
9.3 Configuring Wireless Security Using WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the Router as the AP and NWD210N as the wireless client which connects to a notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter
or PCI card).
There are two WPS methods for creating a secure connection. This tutorial shows you how to do
both.
Chapter 9 Tutorials
NBG6503 User’s Guide
74
•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a
button. See Section 9.3.1 on page 74.This is the easier method.
•PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the Router’s interface. See Section 9.3.2 on page 75. This is
the more secure method, since one device can authenticate the other.
9.3.1 Push Button Configuration (PBC)
1Make sure that your Router is turned on and that it is within range of your computer.
2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or
WPS button)
4Log into Router’s Web Configurator and press the Push Button button in the Network > Wireless
LAN 2.4G or Wireless LAN 5G > WPS Station screen.
Note: Your Router has a WPS button located on its panel, as well as a WPS button in its
configuration utility. Both buttons have exactly the same function; you can use one
or the other.
Note: It doesn’t matter which button is pressed first. You must press the second button
within two minutes of pressing the first one.
The Router sends the proper configuration settings to the wireless client. This may take up to two
minutes. Then the wireless client is able to communicate with the Router securely.

NBG6503 User’s Guide 75
The following figure shows you an example to set up wireless network and security by pressing a
button on both Router and wireless client (the NWD210N in this example).
Figure 51 Example WPS Process: PBC Method
9.3.2 PIN Configuration
When you use the PIN configuration method, you need to use both Router’s configuration interface
and the client’s utilities.
1Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method
to get a PIN number.
2Enter the PIN number to the PIN field in the Network > Wireless LAN 2.4G or Wireless LAN
5G > WPS Station screen on the Router.
3Click Start button (or button next to the PIN field) on both the wireless client utility screen and the
Router’s WPS Station screen within two minutes.
The Router authenticates the wireless client and sends the proper configuration settings to the
wireless client. This may take up to two minutes. Then the wireless client is able to communicate
with the Router securely.

Wireless LAN
10.1 Overview
This chapter discusses how to configure the wireless network settings in your Router. See the
appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 59 Example of a Wireless Network
The wireless 2.4G network is the part in the blue circle and wireless 5G network is the part in the
green circle. In these wireless networks, devices A, B and C are called wireless clients. The wireless
clients use the access point (AP) to interact with other devices (such as the printer) or with the
Internet.
10.2 What You Can Do
•Use the General screen (Section 10.4 on page 86) to enable the Wireless LAN, enter the SSID
and select the wireless security mode.
•Use the MAC Filter screen (Section 10.5 on page 90) to allow or deny wireless stations based
on their MAC addresses from connecting to the Router.

•Use the Advanced screen (Section 10.6 on page 91) to allow wireless advanced features, such
as intra-BSS networking and set the RTS/CTS Threshold.
•Use the QoS screen (Section 10.7 on page 93) to set priority levels to services, such as e-mail,
VoIP, chat, and so on.
•Use the WPS screen (Section 10.8 on page 94) to quickly set up a wireless network with strong
security, without having to configure security settings manually.
•Use the WPS Station screen (Section 10.9 on page 95) to add a wireless station using WPS.
•Use the Scheduling screen (Section 10.10 on page 96) to set the times your wireless LAN is
turned on and off.
•Use the WDS screen (Section 10.11 on page 97) to configure Wireless Distribution System on
your Router.
10.3 What You Should Know
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific channel, or
frequency, to send and receive information.
• Every wireless client in the same wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network. It can also protect the
information that is sent in the wireless network.
10.3.1 Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless
network.
10.3.1.1 SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the
SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change
the default SSID to something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for unauthorized devices to
get the SSID. In addition, unauthorized devices can still see the information that is sent in the
wireless network.
10.3.1.2 MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is
usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or
1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds
of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 10 Wireless LAN
NBG6503 User’s Guide 85
00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s
Guide or other documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to
use the wireless network. If a wireless client is allowed to use the wireless network, it still has to
have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the
wireless network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized
wireless client. Then, they can use that MAC address to use the wireless network.
10.3.1.3 Encryption
Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.
The types of encryption you can choose depend on the type of user authentication.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. Suppose the wireless network has two wireless clients. Device A only supports
WEP, and device B supports WEP and WPA-PSK. Therefore, you should set up WEP in the wireless
network.
Note: It is recommended that wireless networks use WPA-PSK or stronger encryption.
IEEE 802.1x and WEP encryption are better than none at all, but it is still possible
for unauthorized devices to figure out the original information pretty quickly.
When you select WPA2-PSK in your Router, you can also select an option (WPA Compatible) to
support WPA as well. In this case, if some wireless clients support WPA and some support WPA2,
you should set up WPA2-PSK (depending on the type of wireless network login) and select the
WPA Compatible option in the Router.
Many types of encryption use a key to protect the information in the wireless network. The longer
the key, the stronger the encryption. Every wireless client in the wireless network must have the
same key.
10.3.1.4 WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a wireless network with strong security, without having to configure
security settings manually. Depending on the devices in your network, you can either press a
button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification
Number) in the devices. Then, they connect and set up a secure network by themselves. See how
to set up a secure wireless network using WPS in the Section 9.3 on page 73.

10.3.1.5 WDS
Wireless Distribution System or WDS security is used between bridged APs. It is independent of the
security between the wired networks and their respective APs. If you do not enable WDS security,
traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same
pre-shared key.
10.4 General Wireless LAN 2.4G/5G Screen
Use this screen to enable the Wireless LAN 2.4G or 5G, enter the SSID and select the wireless
security mode.
Note: If you are configuring the Router from a computer connected to the wireless LAN

A WAN (Wide Area Network) connection is an outside connection to another network or the
Internet. It connects your private networks such as a LAN (Local Area Network) and other
networks, so that a computer in one location can communicate with computers in other locations.

11.2 What You Can Do
•Use the Internet Connection screen (Section 11.4 on page 102) to enter your ISP information
and set how the computer acquires its IP, DNS and WAN MAC addresses.
•Use the Advanced screen (Section 11.5 on page 108) to enable multicasting, configure Windows
networking and bridge.
11.3 What You Need To Know
The information in this section can help you configure the screens for your WAN connection, as well
as enable/disable some advanced features of your Router.

11.3.1 Configuring Your Internet Connection
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username
and password (and service name) for user authentication.
WAN IP Address
The WAN IP address is an IP address for the Router, which makes it accessible from an outside
network. It is used by the Router to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the Router tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP
encapsulation method).
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, you must know the IP address of a computer before you can access
it.
The Router can get the DNS server addresses in the following ways.
1The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2If your ISP dynamically assigns the DNS server IP addresses (along with the Router’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by either using the
factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default
to select the factory assigned default MAC Address.
Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of
the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the
address will be copied to configuration file. It is recommended that you clone the MAC address prior
to hooking up the WAN Port.
Chapter 11 WAN
NBG6503 User’s Guide 101
11.3.2 Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient)
or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of
hosts on the network - not everybody and not just 1.
Figure 72 Multicast Example
In the multicast example above, systems A and D comprise one multicast group. In multicasting,
the server only needs to send one data stream and this is delivered to systems A and D.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership
in a multicast group - it is not used to carry user data. The Router supports both IGMP version 1
(IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the Router queries all directly connected networks to gather group membership. After
that, the Router periodically updates this information. IP multicasting can be enabled/disabled on
the Router LAN and/or WAN interfaces in the Web Configurator (LAN; WAN). Select None to
disable IP multicasting on these interfaces.

11.4.2 PPPoE Encapsulation
The Router supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF 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 dial-up connection using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example Radius).
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 Router (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the Router does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

CHAPTER 12
LAN
12.1 Overview
This chapter describes how to configure LAN settings.
A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is a computer network limited to the immediate area, usually the same building or
floor of a building. The LAN screens can help you configure a LAN DHCP server, manage IP
addresses, and partition your physical network into logical networks.
Figure 77 LAN Example
The LAN screens can help you manage IP addresses.
12.2 What You Can Do
•Use the IP screen (Section 12.4 on page 111) to change the IP address for your Router.
•Use the IP Alias screen (Section 12.5 on page 111) to have the Router apply IP alias to create
LAN subnets.
Chapter 12 LAN
NBG6503 User’s Guide
110
12.3 What You Need To Know
The actual physical connection determines whether the Router ports are LAN or WAN ports. There
are two separate IP networks, one inside the LAN network and the other outside the WAN network
as shown next.
Figure 78 LAN and WAN IP Addresses
The LAN parameters of the Router are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
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.
12.3.1 IP Pool Setup
The Router is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the Router itself) in the lower
range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for mail,
FTP, TFTP, web, etc., that you may have.
12.3.2 LAN TCP/IP
The Router has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.
12.3.3 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The Router supports three logical LAN interfaces via its single physical Ethernet
interface with the Router itself as the gateway for each LAN network.

DHCP Server
13.1 Overview
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 Router’s LAN as a DHCP
server or disable it. When configured as a server, the Router 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.

CHAPTER 14
Network Address Translation (NAT)
14.1 Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in
a packet. For example, the source address of an outgoing packet, used within one network is
changed to a different IP address known within another network.
Each packet has two addresses – a source address and a destination address. For outgoing packets,
NAT maps private (local) IP addresses to globally unique ones required for communication with
hosts on other networks. It replaces the original IP source address in each packet and then
forwards it to the Internet. The Router keeps track of the original addresses and port numbers so
incoming reply packets can have their original values restored. The following figure illustrates this.
Figure 83 NAT Example
For more information on IP address translation, refer to RFC 1631, The IP Network Address
Translator (NAT).
14.2 What You Can Do
•Use the General screen (Section 14.3 on page 118) to enable NAT and set a default server.
•Use the Application screen (Section 14.4 on page 118) o forward incoming service requests to

14.4 NAT Application Screen
Use the Application screen to forward incoming service requests to the server(s) 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. 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.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.

14.5 NAT Advanced Screen
Some services use a dedicated range of ports on the client side and a dedicated range of ports on
the server side. With regular port forwarding you set a forwarding port in NAT to forward a service
(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN).
The problem is that port forwarding only forwards a service to a single LAN IP address. In order to
use the same service on a different LAN computer, you have to manually replace the LAN
computer's IP address in the forwarding port with another LAN computer's IP address.
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take
turns using the service. The Router records the IP address of a LAN computer that sends traffic to
the WAN to request a service with a specific port number and protocol (a "trigger" port). When the
Router's WAN port receives a response with a specific port number and protocol ("incoming" port),
the Router forwards the traffic to the LAN IP address of the computer that sent the request. After
that computer’s connection for that service closes, another computer on the LAN can use the
service in the same manner. This way you do not need to configure a new IP address each time you
want a different LAN computer to use the application.

14.5.1 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.
Figure 87 Trigger Port Forwarding Process: Example
1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a “trigger” port and causes the Router to record Jane’s computer IP address. The
Router associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The Router forwards the traffic to Jane’s computer IP address.
5Only Jane can connect to the Real Audio server until the connection is closed or times out. The
Router times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP
(Transfer Control Protocol/Internet Protocol).
14.5.2 Two Points To Remember About Trigger Ports
1Trigger events only happen on data that is going coming from inside the Router and going to the
outside.
2If an application needs a continuous data stream, that port (range) will be tied up so that another
computer on the LAN can’t trigger it.

Dynamic DNS
15.1 Overview
Dynamic DNS (DDNS) services let you use a domain name with a dynamic IP address.
15.2 What You Can Do
Use the Dynamic DNS screen (Section 15.4 on page 123) to enable DDNS and configure the DDNS
settings on the Router.
15.3 What You Need To Know
Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic
DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access
your FTP server or Web site on your own computer using a domain name (for instance
myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an
IP address that changes each time you reconnect. Your friends or relatives will always be able to
call you even if they don't know your IP address.

Static Route
16.1 Overview
This chapter shows you how to configure static routes for your Router.
Each remote node specifies only the network to which the gateway is directly connected, and the
Router has no knowledge of the networks beyond. For instance, the Router knows about network
N2 in the following figure through remote node Router 1. However, the Router is unable to route a
packet to network N3 because it doesn't know that there is a route through the same remote node
Router 1 (via gateway Router 2). The static routes are for you to tell the Router about the networks
beyond the remote nodes.

CHAPTER 17
Firewall
17.1 Overview
This chapter shows you how to enable and configure the firewall that protects your Router and your
LAN from unwanted or malicious traffic.
Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and
control access between the LAN and WAN. By default the firewall:
• allows traffic that originates from your LAN computers to go to all of the networks.
• blocks traffic that originates on the other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant
Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2).
However other traffic initiated from the WAN is blocked (3 and 4).
Figure 91 Default Firewall Action
17.2 What You Can Do
•Use the General (Section 17.4 on page 130) screen to enable or disable the Router’s firewall.

17.3 What You Need To Know
The Router’s firewall feature physically separates the LAN and the WAN and acts as a secure
gateway for all data passing between the networks.
It is designed to protect against Denial of Service (DoS) attacks when activated (click the General
tab under Firewall and then click the Enable Firewall check box). The Router's purpose is to
allow a private Local Area Network (LAN) to be securely connected to the Internet. The Router can
be used to prevent theft, destruction and modification of data, as well as log events, which may be
important to the security of your network.
The Router is installed between the LAN and a broadband modem connecting to the Internet. This
allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The Router has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically
separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband
(cable or DSL) modem to the Internet.
The LAN (Local Area Network) port attaches to a network of computers, which needs security from
the outside world. These computers will have access to Internet services such as e-mail, FTP and
the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host
is authorized to use a specific service.

Content Filter
18.1 Overview
This chapter provides a brief overview of content filtering using the embedded web GUI.
Internet content filtering allows you to create and enforce Internet access policies tailored to your
needs. Content filtering is the ability to block certain web features or specific URL keywords.
18.2 What You Can Do
Use the Content Filter (Section 18.4 on page 134) screen to restrict web features, add
keywords for blocking and designate a trusted computer.
18.3 What You Need To Know
Content filtering allows you to block certain web features, such as cookies, and/or block access to
specific web sites. For example, you can configure one policy that blocks John Doe’s access to arts
and entertainment web pages.
18.3.1 Content Filtering Profiles
A content filtering profile conveniently stores your custom settings for the following features.
Restrict Web Features
The Router can disable web proxies and block web features such as ActiveX controls, Java applets
and cookies.
Keyword Blocking URL Checking
The Router checks the URL’s domain name (or IP address) and file path separately when performing
keyword blocking.
The URL’s domain name or IP address is the characters that come before the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is
www.zyxel.com.tw.
The file path is the characters that come after the first slash in the URL. For example, with the URL
www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.
Chapter 18 Content Filter
NBG6503 User’s Guide
134
Since the Router checks the URL’s domain name (or IP address) and file path separately, it will not
find items that go across the two. For example, with the URL www.zyxel.com.tw/news/
pressroom.php, the Router would find “tw” in the domain name (www.zyxel.com.tw). It would also
find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.

CHAPTER 21
Universal Plug-and-Play (UPnP)
21.1 Overview
This chapter introduces the UPnP feature in the web configurator.
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
21.2 What You Can Do
Use the UPnP screen (Section 21.4 on page 148) to enable UPnP on your Router.
21.3 What You Need to Know
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP
compatible device installed on your network will appear as a separate icon. Selecting the icon of a
UPnP device will allow you to access the information and properties of that device.
21.3.1 NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP
network devices can automatically configure network addressing, announce their presence in the
network to other UPnP devices and enable exchange of simple product and service descriptions.
NAT traversal allows the following:
• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the NAT chapter for more information on NAT.
Chapter 21 Universal Plug-and-Play (UPnP)
NBG6503 User’s Guide
148
21.3.2 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configuration may also
be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the Router allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.

local time. So in the United States you would select First, Sunday, April and select 2 in
the o'clock field.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of the
time zones in the European Union start using Daylight Saving Time at the same moment
(1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March.
The time you select in the o'clock field depends on your time zone. In Germany for
instance, you would select 2 because Germany's time zone is one hour ahead of GMT or
UTC (GMT+1).
End Date Configure the day and time when Daylight Saving Time ends if you selected Daylight
Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time ends in the United States on the last Sunday of October. Each time
zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So in the
United States you would select Last, Sunday, October and select 2 in the o'clock field.
Daylight Saving Time ends in the European Union on the last Sunday of October. All of the
time zones in the European Union stop using Daylight Saving Time at the same moment

23.2 Router Access and Login
I don’t know the IP address of my Router.
1The default IP address is 192.168.1.1.
2If you changed the IP address and have forgotten it, you might get the IP address of the Router by
looking up the IP address of the default gateway for your computer. To do this in most Windows
computers, click Start > Run, enter cmd, and then enter ipconfig. The IP address of the Default
Gateway might be the IP address of the Router (it depends on the network), so enter this IP
address in your Internet browser.Set your device to Router Mode, login (see the Quick Start Guide
for instructions) and go to the Device Information table in the Status screen. Your Router’s IP
address is available in the Device Information table.
•If the DHCP setting under LAN information is None, your device has a fixed IP address.
•If the DHCP setting under LAN information is Client, then your device receives an IP
address from a DHCP server on the network.
3If your Router is a DHCP client, you can find your IP address from the DHCP server. This information
is only available from the DHCP server which allocates IP addresses on your network. Find this
information directly from the DHCP server or contact your system administrator for more
information.
4Reset your Router to change all settings back to their default. This means your current settings are
lost. See Section 23.4 on page 169 in the Troubleshooting for information on resetting your

APPENDIX A
IP Addresses and Subnetting
This appendix introduces IP addresses and subnet masks.
IP addresses identify individual devices 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.
Subnet masks determine the maximum number of possible hosts on a network. You can also use
subnet masks to divide one network into multiple sub-networks.
Introduction to IP Addresses
One part of the IP address is the network number, and the other part is the host ID. In the same
way that houses on a street share a common street name, the hosts on a network share a common
network number. Similarly, as each house has its own house number, each host on the network has
its own unique identifying number - the host ID. Routers use the network number to send packets
to the correct network, while the host ID determines to which host on the network the packets are
delivered.
Structure
An IP address is made up of four parts, written in dotted decimal notation (for example,
192.168.1.1). Each of these four parts is known as an octet. An octet is an eight-digit binary
number (for example 11000000, which is 192 in decimal notation).
Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in
decimal.
Appendix A IP Addresses and Subnetting
NBG6503 User’s Guide
172
The following figure shows an example IP address in which the first three octets (192.168.1) are
the network number, and the fourth octet (16) is the host ID.
Figure 122 Network Number and Host ID
How much of the IP address is the network number and how much is the host ID varies according
to the subnet mask.
Subnet Masks
A subnet mask is used to determine which bits are part of the network number, and which bits are
part of the host ID (using a logical AND operation). The term “subnet” is short for “sub-network”.
A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the corresponding bit in the IP
address is part of the network number. If a bit in the subnet mask is “0” then the corresponding bit
in the IP address is part of the host ID.
The following example shows a subnet mask identifying the network number (in bold text) and host
ID of an IP address (192.168.1.2 in decimal).
By convention, subnet masks always consist of a continuous sequence of ones beginning from the
leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.
Subnet masks can be referred to by the size of the network number part (the bits with a “1” value).
For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24
bits are zeroes.

Subnet masks are expressed in dotted decimal notation just like IP addresses. The following
examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks.
Network Size
The size of the network number determines the maximum number of possible hosts you can have
on your network. The larger the number of network number bits, the smaller the number of
remaining host ID bits.
An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 with a 24-bit
subnet mask, for example). An IP address with host IDs of all ones is the broadcast address for that
network (192.168.1.255 with a 24-bit subnet mask, for example).
As these two IP addresses cannot be used for individual hosts, calculate the maximum number of
possible hosts in a network as follows:
Notation
Since the mask is always a continuous number of ones beginning from the left, followed by a
continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the
number of ones instead of writing the value of each octet. This is usually specified by writing a “/”
followed by the number of bits in the mask after the address.
For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128.
The following table shows some possible subnet masks using both notations.

Subnetting
You can use subnetting to divide one network into multiple sub-networks. In the following example
a network administrator creates two sub-networks to isolate a group of servers from the rest of the
company network for security reasons.
In this example, the company network address is 192.168.1.0. The first three octets of the address
(192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum
of 28 – 2 or 254 possible hosts.
The following figure shows the company network before subnetting.
Figure 123 Subnetting Example: Before Subnetting
You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-
networks. The subnet mask is now 25 bits (255.255.255.128 or /25).
The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25
and 192.168.1.128 /25.

The following figure shows the company network after subnetting. There are now two sub-
networks, A and B.
Figure 124 Subnetting Example: After Subnetting
In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126
possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s
broadcast address).
192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask
255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to
an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126.
Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.
Example: Four Subnets
The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two
subnets. Similarly, to divide a 24-bit address into four subnets, you need to “borrow” two host ID
bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits
(11111111.11111111.11111111.11000000) or 255.255.255.192.
Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a host ID of all
zeroes is the subnet itself, all ones is the subnet’s broadcast address).

Configuring IP Addresses
Where you obtain your network number depends on your particular situation. If the ISP or your
network administrator assigns you a block of registered IP addresses, follow their instructions in
selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user
account and the ISP will assign you a dynamic IP address when the connection is established. If this
is the case, it is recommended that you select a network number from 192.168.0.0 to
192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block of addresses
specifically for private use; please do not use any other number unless you are told otherwise. You
must also enable Network Address Translation (NAT) on the Router.
Once you have decided on the network number, pick an IP address for your Router that is easy to
remember (for instance, 192.168.1.1) but make sure that no other device on your network is using
that IP address.
The subnet mask specifies the network number portion of an IP address. Your Router will compute
the subnet mask automatically based on the IP address that you entered. You don't need to change
the subnet mask computed by the Router unless you are instructed to do otherwise.
Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the
Internet (running only between two branch offices, for example) you can assign any IP addresses to
the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has
reserved the following three blocks of IP addresses specifically for private networks:
• 10.0.0.0 — 10.255.255.255
• 172.16.0.0 — 172.31.255.255
• 192.168.0.0 — 192.168.255.255
You can obtain your IP address from the IANA, from an ISP, or it can be assigned from a private
network. If you belong to a small organization and your Internet access is through an ISP, the ISP
can provide you with the Internet addresses for your local networks. On the other hand, if you are
part of a much larger organization, you should consult your network administrator for the
appropriate IP addresses.
Regardless of your particular situation, do not create an arbitrary IP address; always follow the
guidelines above. For more information on address assignment, please refer to RFC 1597, Address
Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.

IP Address Conflicts
Each device on a network must have a unique IP address. Devices with duplicate IP addresses on
the same network will not be able to access the Internet or other resources. The devices may also
be unreachable through the network.
Conflicting Computer IP Addresses Example
More than one device can not use the same IP address. In the following example computer A has a
static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to
computer B which is a DHCP client. Neither can access the Internet. This problem can be solved by
assigning a different static IP address to computer A or setting computer A to obtain an IP address
automatically.
Figure 125 Conflicting Computer IP Addresses Example
Conflicting Router IP Addresses Example
Since a router connects different networks, it must have interfaces using different network
numbers. For example, if a router is set between a LAN and the Internet (WAN), the router’s LAN
and WAN addresses must be on different subnets. In the following example, the LAN and WAN are
on the same subnet. The LAN computers cannot access the Internet because the router cannot
route between networks.

Conflicting Computer and Router IP Addresses Example
More than one device can not use the same IP address. In the following example, the computer and
the router’s LAN port both use 192.168.1.1 as the IP address. The computer cannot access the
Internet. This problem can be solved by assigning a different IP address to the computer or the
router’s LAN port.

Wireless LANs
Wireless LAN Topologies
This section discusses ad-hoc and infrastructure wireless LAN topologies.
Ad-hoc Wireless LAN Configuration
The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of
computers with wireless adapters (A, B, C). 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 134 Peer-to-Peer Communication in an Ad-hoc Network
BSS
A Basic Service Set (BSS) exists when all communications between wireless clients or between a
wireless client and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless
client A and B can access the wired network and communicate with each other. When Intra-BSS is
Appendix C Wireless LANs
NBG6503 User’s Guide
210
disabled, wireless client A and B can still access the wired network but cannot communicate with
each other.
Figure 135 Basic Service Set
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).
This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only
provide communication with the wired network but also mediate wireless network traffic in the
immediate neighborhood.
Appendix C Wireless LANs
NBG6503 User’s Guide 211
An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated
wireless clients within the same ESS must have the same ESSID in order to communicate.
Figure 136 Infrastructure WLAN
Channel
A channel is the radio frequency(ies) used by wireless devices to transmit and receive data.
Channels available depend on your geographical area. You may have a choice of channels (for your
region) so you should use a channel different from an adjacent AP (access point) to reduce
interference. Interference occurs when radio signals from different access points overlap causing
interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should
be on a channel at least five channels away from a channel that an adjacent AP is using. For
example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to
select a channel between 6 or 11.
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
Appendix C Wireless LANs
NBG6503 User’s Guide
212
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 137 RTS/CTS
When station A sends data to the AP, it might not know that the 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.
RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest
size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is
invoked.
When a data frame exceeds the RTS/CTS value you set, the station that wants to transmit this
frame must first send an RTS (Request To Send) message to the AP for permission to send it. The
AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify
them to defer their transmission. It also reserves and confirms with the requesting station the time
frame for the requested transmission.
Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS
(Request To Send)/CTS (Clear to Send) handshake.
You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and
the "cost" of resending large frames is more than the extra network overhead involved in the RTS
(Request To Send)/CTS (Clear to Send) handshake.
If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the
RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be
fragmented before they reach RTS/CTS size.
Note: Enabling the RTS Threshold causes redundant network overhead that could
negatively affect the throughput performance instead of providing a remedy.
Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size that can be sent in the wireless
network before the AP will fragment the packet into smaller data frames.
A large Fragmentation Threshold is recommended for networks not prone to interference while
you should set a smaller threshold for busy networks or networks that are prone to interference.
Appendix C Wireless LANs
NBG6503 User’s Guide 213
If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you
set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames
will be fragmented before they reach RTS/CTS size.
Preamble Type
Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of
the synchronization field in a packet.
Short preamble increases performance as less time sending preamble means more time for sending
data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short
preamble.
Use long preamble if you are unsure what preamble mode other wireless devices on the network
support, and to provide more reliable communications in busy wireless networks.
Use short preamble if you are sure all wireless devices on the network support it, and to provide
more efficient communications.
Use the dynamic setting to automatically use short preamble when all wireless devices on the
network support it, otherwise the Router uses long preamble.
Note: The wireless devices MUST use the same preamble mode in order to communicate.
Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless
clients, access points and the wired network.
Wireless security methods available on the Router are data encryption, wireless client
authentication, restricting access by device MAC address and hiding the Router identity.
The following figure shows the relative effectiveness of these wireless security methods available on
your Router.
Note: You must enable the same wireless security settings on the Router and on all
wireless clients that you want to associate with it.

Appendix C Wireless LANs
NBG6503 User’s Guide
214
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. Some advantages of IEEE 802.1x
are:
• 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.
RADIUS
RADIUS is based on a client-server model that supports authentication, authorization and
accounting. The access point is the client and the server is the RADIUS server. The RADIUS server
handles the following tasks:
• Authentication
Determines the identity of the users.
•Authorization
Determines the network services available to authenticated users once they are connected to the
network.
• Accounting
Keeps track of the client’s network activity.
RADIUS is a simple package exchange in which your AP acts as a message relay between the
wireless client and the network RADIUS server.
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.
• 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:
Appendix C Wireless LANs
NBG6503 User’s Guide 215
• Accounting-Request
Sent by the access point requesting accounting.
• Accounting-Response
Sent by the RADIUS server to indicate that it has started or stopped accounting.
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 network from
unauthorized access.
Types of EAP Authentication
This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and
LEAP. Your wireless LAN device may not support all authentication types.
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE
802.1x transport mechanism in order to support multiple types of user authentication. By using EAP
to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a
RADIUS server perform authentication.
The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that
supports IEEE 802.1x. .
For EAP-TLS authentication type, you must first have a wired connection to the network and obtain
the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used
to authenticate users and a CA issues certificates and guarantees the identity of each certificate
owner.
EAP-MD5 (Message-Digest Algorithm 5)
MD5 authentication is the simplest one-way authentication method. The authentication server
sends a challenge to the wireless client. The wireless client ‘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 clients 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.
Appendix C Wireless LANs
NBG6503 User’s Guide
216
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.
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.
LEAP
LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x.
Dynamic WEP Key Exchange
The AP maps a unique key that is generated with the RADIUS server. This key expires when the
wireless connection times out, disconnects or reauthentication times out. A new WEP key is
generated each time reauthentication is performed.
If this feature is enabled, it is not necessary to configure a default encryption key in the wireless
security configuration screen. You may still configure and store keys, but they will not be used while
dynamic WEP is enabled.
Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange
For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic
keys for data encryption. They are often deployed in corporate environments, but for public
deployment, a simple user name and password pair is more practical. The following table is a
comparison of the features of authentication types.
Table 83 Comparison of EAP Authentication Types

NBG6503 User’s Guide 217
WPA and WPA2
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a
wireless security standard that defines stronger encryption, authentication and key management
than WPA.
Key differences between WPA or WPA2 and WEP are improved data encryption and user
authentication.
If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use
WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use
WPA2-PSK (WPA2-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 wireless
client will be granted access to a WLAN.
If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on
whether you have an external RADIUS server or not.
Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less
secure than WPA or WPA2.
Encryption
WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity
Check (MIC) and IEEE 802.1x. WPA2 also uses TKIP when required for compatibility reasons, but
offers stronger encryption than TKIP with Advanced Encryption Standard (AES) in the Counter
mode with Cipher block chaining Message authentication code Protocol (CCMP).
TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server.
AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm
called Rijndael. They both include 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.
WPA and WPA2 regularly change and rotate 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 PMK 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), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi
network than WEP and difficult for an intruder to break into the network.
The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference
between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific
credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force
Appendix C Wireless LANs
NBG6503 User’s Guide
218
password-guessing attacks but it’s still an improvement over WEP as it employs a consistent,
single, alphanumeric password to derive a PMK which is used to generate unique temporal
encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of
WEP)
User Authentication
WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate
wireless clients using an external RADIUS database. WPA2 reduces the number of key exchange
messages from six to four (CCMP 4-way handshake) and shortens the time required to connect to a
network. Other WPA2 authentication features that are different from WPA include key caching and
pre-authentication. These two features are optional and may not be supported in all wireless
devices.
Key caching allows a wireless client to store the PMK it derived through a successful authentication
with an AP. The wireless client uses the PMK when it tries to connect to the same AP and does not
need to go with the authentication process again.
Pre-authentication enables fast roaming by allowing the wireless client (already connecting to an
AP) to perform IEEE 802.1x authentication with another AP before connecting to it.
Wireless Client WPA Supplicants
A wireless client supplicant is the software that runs on an operating system instructing the wireless
client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch
for Windows XP, Funk Software's Odyssey client.
The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero
Configuration" wireless client. However, you must run Windows XP to use it.
WPA(2) with RADIUS Application Example
To set up WPA(2), you need the IP address of the RADIUS server, its port number (default is 1812),
and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server
looks as follows. "A" is the RADIUS server. "DS" is the distribution system.
1The AP passes the wireless client's authentication request to the RADIUS server.
2The RADIUS server then checks the user's identification against its database and grants or denies
network access accordingly.
3A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS
server and the client.
Appendix C Wireless LANs
NBG6503 User’s Guide 219
4The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and
management system, using the PMK to dynamically generate unique data encryption keys. The
keys are used to encrypt every data packet that is wirelessly communicated between the AP and
the wireless clients.
Figure 138 WPA(2) with RADIUS Application Example
WPA(2)-PSK Application Example
A WPA(2)-PSK application looks as follows.
1First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must
consist of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and
symbols).
2The AP checks each wireless client's password and allows it to join the network only if the password
matches.
3The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not
sent over the network, but is derived from the PSK and the SSID.
Appendix C Wireless LANs
NBG6503 User’s Guide
220
4The AP and wireless clients use the TKIP or AES encryption process, the PMK and information
exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data
exchanged between them.

Positioning the antennas properly increases the range and coverage area of a wireless LAN.
Antenna Characteristics
Frequency
An antenna in the frequency of 2.4GHz or 5GHz 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.
• 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 does with the light
from its bulb. The angle of the beam determines the width of the coverage pattern. Angles
typically range from 20 degrees (very directional) to 120 degrees (less directional). 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 antennas at the same height and in a direct line of sight to
each other to attain 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.
