ZyAIR G-4100 User’s Guide
Chapter 1
Getting to Know Your ZyAIR
This chapter introduces the features and applications of the ZyAIR.
1.1
Introducing the ZyAIR
The ZyAIR Hot Spot Gateway combines an IEEE 802.11g wireless access point, router, 4-port switch
and service gateway in one box. An “exclusive printer” connects directly to the ZyAIR, allowing you
to easily print subscriber statements. The ZyAIR is ideal for offices, coffee shops, libraries, hotels and
airport terminals catering to subscribers that seek Internet access. You should have an Internet account
already set up and have been given usernames, passwords etc. required for Internet access.
1.2
Features
Your ZyAIR provides the following features to accommodate subscribers with a variety of network
configurations with little or no technical support.
iPnP
The IP Plug and Play feature allows a computer to access the Internet or the ZyAIR without changing
the network settings (such as IP address and subnet mask) of the computer, even when the IP
addresses of the computer and the ZyAIR are not in the same subnet.
WEP Data Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network
to help keep network communications private. The ZyAIR uses 64-bit or 128-bit WEP encryption.
WPA Data Encryption
Wi-Fi Protected Access (WPA) encrypts data frames before transmitting over the wireless network to
help keep network communications private. WPA provides user authentication and better data
encryption than WEP.
VPN (Virtual Private Network) Pass Through
The ZyAIR allows subscribers to create VPN networks (which use data encryption and the Internet to
provide secure communications) that go through the ZyAIR.
VLAN
The ZyAIR can use VLANs (Virtual Local Area Network) to partition the physical network into
multiple logical networks in order to stop subscribers from seeing each other’s data. The ZyAIR also
provides a port-based VLAN via the four 10/100Mbps auto-negotiating Ethernet ports.
SSL Secure Login
With Secure Socket Layer (SSL) activated upon login, data exchanged between the ZyAIR and client
computers are encrypted and protected.
Getting to Know Your ZyAIR
1-1
ZyAIR G-4100 User’s Guide
PPTP Support
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/IPbased network. PPTP supports on-demand, multi-protocol and virtual private networking over public
networks, such as the Internet. Use PPTP to connect to a broadband modem to achieve access to highspeed data networks via a familiar "dial-up networking" user interface.
PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to
use their existing network configuration with newer broadband technologies such as ADSL. The
PPPoE driver on the ZyAIR is transparent to the computers on the LAN, which see only Ethernet and
are not aware of PPPoE thus saving you from having to manage PPPoE clients on individual
computers.
Network Address Translation (NAT)
NAT (Network Address Translation - NAT, RFC 1631) allows the translations of multiple IP
addresses used within one network to different IP addresses known within another network.
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows the individual computers (DHCP clients) to
obtain TCP/IP configuration at start-up from a centralized DHCP server. The ZyAIR has built-in
DHCP server capability. It can assign IP addresses, an IP default gateway and DNS servers to DHCP
clients. The ZyAIR can also act as a surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the DHCP clients.
E-mail Forwarding
The ZyAIR is able to forward and retrieve e-mail messages when the subscriber’s default email server
is down or behind a firewall.
DNS Proxy
With DNS proxy, the ZyAIR provides DNS redirection when a subscriber’s configured DNS server is
behind a firewall or located in a private Intranet.
Local Subscriber Database
The ZyAIR allows you to maintain a subscriber database on the ZyAIR without setting up an external
RADIUS server. Subscriber accounting and authentication are done using the local subscriber
database.
Accounting
Accounting can be done using the built-in accounting feature.
Local Content and Advertising Links
Once connected to the network, the ZyAIR directs the subscriber to a specified web site and display
advertisement links. This can be a source of extra online advertising revenues and increased business
exposure.

Getting to Know Your ZyAIR
ZyAIR G-4100 User’s Guide
Access Control (Walled Garden)
With the walled garden feature, subscribers are able to access predetermined web sites without logging
in. The ZyAIR blocks full Internet access until the subscribers log in.
Subscriber Login Page Customization
You can customize the subscriber login page according to your business needs. The advanced settings
allow you to include welcome messages, company logo and basic formatting.
Web Configurator Management
The ZyAIR comes with an embedded web-based configurator. It offers advanced management features
and allows you to manage the ZyAIR remotely using Internet Explorer.
Watchdog
The ZyAIR can continue working by resetting itself after a system crash.
Upgrade Firmware
The firmware of the ZyAIR can be upgraded via the web configurator.
Syslog
The ZyAIR’s syslog function allows network administrators to monitor the usage status of subscribers
from a remote site. You can set up a syslog server to receive the log of information on current loggedin subscribers that the ZyAIR sends periodically.
IEEE 802.11g Wireless LAN Standard
The ZyAIR complies with the IEEE 802.11g wireless standard, which supports data speeds of up to 54
Mbps.
IEEE 802.11b Wireless LAN Standard
The ZyAIR is also fully compatible with the 802.11b standard. This means an IEEE 802.11b radio
card can interface directly with the ZyAIR (and vice versa) at 11 Mbps or lower depending on range.
Antennas
The ZyAIR is equipped with two reverse SMA connectors and two detachable omni-directional 2dBi
antennas to provide a clear radio signal between the wireless stations and the access points. Refer to
the Antennas appendix for more information.
4-Port Switch
A combination of switch and Internet gateway makes your ZyAIR a cost-effective and viable network
solution. You can connect up to four computers to the LAN ports on the ZyAIR without the cost of a
hub. To connect more than four Ethernet devices, attach a hub or switch.
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface
This auto-negotiating feature allows the ZyAIR to detect the speed of incoming transmissions and
adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100
Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Reset Button
Use the reset button to restore the ZyAIR back to its factory defaults.

ZyAIR G-4100 User’s Guide
Statement Printer
A compact statement printer comes with your ZyAIR. The statement printer allows you to generate
subscriber accounts on the ZyAIR and print out the account information on-site without using a
computer.
The statement printer is also known as an “account generator” or “exclusive printer”.
Ease of Installation
Your ZyAIR is designed for quick, intuitive and easy installation. It can be mounted on a desktop or a
wall.
1.3
Applications
The following sections describe network application examples in which the ZyAIR is used.
1.3.1 Internet Access for LAN Networks
With a broadband modem or router (A), the ZyAIR allows the attached computers to enjoy high speed
Internet access.
Figure 1-1 Application: Internet Access for LAN Networks
1.3.2 Internet Access in Public Areas
In public areas, such as a hotel, the ZyAIR provides high speed Internet access to subscribers. Account
billing and authentication can be done using the statement printer (B) and the built-in billing function
and local subscriber database.
The ZyAIR functions as an access point (AP) to bridge the wired and the wireless network allowing
wireless stations to access the Internet through the ZyAIR.

General System Setup
Use this screen to configure administrative and system-related general settings for your ZyAIR.
3.2
System Name
System Name is for identification purposes. However, because some ISPs check this name you should
enter your computer's "Computer Name".
•
In Windows 95/98 click Start, Settings, Control Panel, Network. Click the Identification tab,
note the entry for the Computer Name field and enter it as the System Name.
•
In Windows 2000, click Start, Settings and Control Panel and then double-click System. Click
the Network Identification tab and then the Properties button. Note the entry for the Computer
name field and enter it as the System Name.
•
In Windows XP, click Start, My Computer, View system information and then click the
Computer Name tab. Note the entry in the Full computer name field and enter it as the ZyAIR
System Name.
3.3
Domain Name
The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this
blank, the domain name obtained by a DHCP server is used. While you must enter the host name
(System Name), the domain name can be assigned from the ZyAIR via DHCP.
3.4
iPnP
Traditionally, you must set the IP addresses and the subnet masks of a computer and the ZyAIR to be
in the same subnet to allow the computer to access the Internet (through the ZyAIR). In cases where
your computer is required to use a static IP address in another network, you may need to manually
configure the network settings of the computer every time you want to access the Internet via the
ZyAIR.
With the iPnP feature and NAT enabled, the ZyAIR allows a computer to access the Internet without
changing the network settings (such as IP address and subnet mask) of the computer, when the IP
addresses of the computer and the ZyAIR are not in the same subnet. Whether a computer is set to use
a dynamic or static (fixed) IP address, you can simply connect the computer to the ZyAIR and access
the Internet.
The following figure depicts a scenario where a computer is set to use a static private IP address in the
corporate environment. In a residential house where a ZyAIR is installed, you can still use the
computer to access the Internet without changing the network settings, even when the IP addresses of
the computer and the ZyAIR are not in the same subnet.
General System Setup
3-1
ZyAIR G-4100 User’s Guide
The iPnP feature does not apply to a computer using either a dynamic IP address or a static IP address
that is in the same subnet as the ZyAIR’s IP address.
You must enable NAT to use the iPnP feature.
3.4.1 How iPnP Works
Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address)
to a physical machine address, also known as a Media Access Control or MAC address, on the local
area network. IP routing table is defined on IP Ethernet devices (the ZyAIR) to decide which hop to
use, to help forward data along to its specified destination.
The following lists out the steps taken, when a computer tries to access the Internet for the first time
through the ZyAIR.
1. When a computer (which is in a different subnet) first attempts to access the Internet, it sends
packets to its default gateway (which is not the ZyAIR) by looking at the MAC address in its ARP
table.
2. When the computer cannot locate the default gateway, an ARP request is broadcast on the LAN.
3. The ZyAIR receives the ARP request and replies to the computer with its own MAC address.
4. The computer updates the MAC address for the default gateway to the ARP table. Once the ARP
table is updated, the computer is able to access the Internet through the ZyAIR.
5. When the ZyAIR receives packets from the computer, it creates an entry in the IP routing table so it
can properly forward packets intended for the computer.
After all the routing information is updated, the computer can access the ZyAIR and the Internet as if
it is in the same subnet as the ZyAIR.

Chapter 4
WAN, LAN and Server Setup
This chapter shows you how to configure LAN and WAN ports and server settings.
4.1
Factory Ethernet Defaults
The Ethernet parameters of the ZyAIR are preset to the following values:
•
Dynamic WAN IP address.
•
LAN IP address of 192.168.1.1 with subnet mask of 255.255.255.0
•
DHCP server enabled on the LAN with a 253 client IP address pool starting from
192.168.1.2.
These parameters should work for the majority of installations. If you wish to change the factory
defaults or to learn more about TCP/IP, please read on.
4.2
LANs and WANs
A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same
building or floor of a building. A WAN (Wide Area Network), on the other hand, is an outside
connection to another network or the Internet.
4.3
IP Address Assignment
A static IP is a fixed IP that the ZyAIR obtains from a DHCP server on a network. A dynamic IP is not
fixed; the DHCP server provides an IP address to the ZyAIR each time it connects to the network.
When an Ethernet device is configured to obtain a dynamic IP address from a DHCP server, it is
known as a DHCP client.
4.4
DHCP Configuration
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (Ethernet device) to
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The ZyAIR has built-in
DHCP server capability, which means it can assign IP addresses, an IP default gateway and DNS
servers to computer systems that support the DHCP client when this feature is activated. The ZyAIR
can also act as a surrogate DHCP server where it relays IP address assignment from the actual DHCP
server to the clients.
4.4.1 IP Address and Subnet Mask
Like houses on a street that share a common street name, the computers on a LAN share one common
network number.
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.
The Internet Assigned Number Authority (IANA) reserved a block of addresses specifically for private
use (refer to Section 4.4.2); please do not use any other number unless you are told otherwise. Let’s
WAN, LAN and Server Setup
4-1
ZyAIR G-4100 User’s Guide
say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from
192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers
specify the network number while the last number identifies an individual computer on that network.
The subnet mask specifies the network number portion of an IP address.
4.4.2 Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the
Internet, for example, only between your two branch offices, 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.
4.5
DNS Server Address
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
machine before you can access it. The DNS server addresses that you enter in the DHCP setup are
passed to the client machines along with the assigned IP address and subnet mask.
There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a
customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up.
The second is to obtain the DNS server information automatically when a computer is set as a DHCP
client.
4.6
PPPoE
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. It preserves the existing Microsoft Dial-Up Networking experience and requires no new
learning or procedures.
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.
4-2
WAN, LAN and Server Setup
ZyAIR G-4100 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 ZyAIR (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the ZyAIR does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.
4.6.1 PPP MTU
A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-bit
bytes) that can be sent in a packet- or frame-based network. The Transmission Control Protocol (TCP)
uses the MTU to determine the maximum size of each packet in any transmission. Too large an MTU
size may mean retransmissions if the packet encounters a router that can't handle that large a packet.
Too small an MTU size means relatively more header overhead and more acknowledgements that
have to be sent and handled.
4.6.2 TCP MSS
The maximum segment size (MSS) is the largest amount of data, specified in bytes, that a computer or
communications device can handle in a single, unfragmented piece. For optimum communications, the
number of bytes in the data segment and the header must add up to less than the number of bytes in the
maximum transmission unit (MTU).
4.7
PPTP
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers of data from a
remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based
networks.
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks, such
as the Internet.

Billing
This chapter shows you how to set up subscriber billing on the ZyAIR.
6.1
About the Built-in Billing
You can use the built-in billing function to setup billing profiles. A billing profile describes how to
charge subscribers.
6.1.1 Accumulation Accounting Method
The accumulation accounting method allows multiple re-logins until the allocated time period or until
the subscriber account is expired. The ZyAIR accounts for the time the subscriber logs in for Internet
access.
6.1.2 Time-to-finish Accounting Method
The time-to-finish accounting method is good for one-time logins. Once a subscriber logs in, the
ZyAIR stores the MAC address of the subscriber’s computer for the duration of the time allocated.
Thus the subscriber does not have to enter the user name and password again for re-login within the
allocated time.
Once activated, the subscriber account is valid until the allocated time is reached even if the subscriber
disconnects Internet access for a certain period within the allocated time. For example, Joe purchases a
one-hour time-to-finish account. He starts using the Internet for the first 20 minutes and then
disconnects his Internet access to go to a 20-minute meeting. After the meeting, he only has 20
minutes left on his account.

Accounting
This chapter shows you how to set up and manage subscriber accounts.
7.1
About Subscriber Accounts
Once the time allocated to a dynamic account is used up or a dynamic account remains un-used after
the expiration time, the account is deleted from the account list. Accounts are automatically generated
either by pressing a button on the connected exclusive printer or using the web configurator (the
Account Generator Panel screen).
7.2
Discount Price Plan
You can configure a custom discount pricing plan. This is useful for providing reduced rates for
purchases of longer periods of time. You can charge higher rates per unit at lower levels (fewer units
purchased) and lower rates per unit at higher levels (more units purchased).
The discount price plan only works when the hot spot operator does the billing through the statement
printer or the web-based account generator panel. The discount price plan does not apply to
subscribers purchasing access time online with a credit card.
7.2.1 Charge by Levels
The discount price plan gives you the option to charge by levels. This allows you to charge the rate at
each successive level from the first level (most expensive per unit) to the highest level (least expensive
per unit) that the total purchase reaches.
Otherwise you can disable the charge by level function and charge all of the time units only at the
highest (least expensive) level that the total purchase reaches.
See section 7.3.1 for an example of the charge by levels accounting function.

7.3.1 Charge By Levels Example
This is an example of how charge by levels accounting works. The discount price plan allows you to
make the unit price lower as the subscriber purchases more (meaning a higher number of button
pushes). The Unit Price for level 1 is always the same as the base charge ($2.00 for this example).
The following screen has discount price level 2 set to $1.75 and level 3 set to $1.50. Taxes are not
included in this example.
Figure 7-2 Charge By Levels Example
A subscriber purchases 11 units. Without charge by levels accounting, the total would be the number
of button presses (11) multiplied by the unit price for the level that the number of button presses
matches. In this case it would be 11x $1.50 for a total of $16.50 (excluding tax).
7-4
Accounting
ZyAIR G-4100 User’s Guide
With charge by levels accounting, you charge the subscriber the rate at each successive level from the
first level (most expensive per unit) to the highest level (least expensive per unit) that the purchase
reaches. In this example, the ZyAIR would charge as follows:
Table 7-2 Charge By Levels Example
The base charge ($2.00) per unit for button presses 1-4.
($2.00 x 4= $8.00)
The level 2, unit price ($1.75) per unit for button presses 5-9.
($1.75 x 5= $8.75)
The level 3, unit price ($1.50) per unit for button presses 10-11.
($1.50 x 2= $3.00)
For a total of:

Pass Through
This chapter shows you how to specify devices that can have traffic pass through the ZyAIR.
11.1 About the Pass Through
You can set up two types of pass through on the ZyAIR: by device or by web site address.
You can set the ZyAIR to allow specific computers on the LAN (based on the IP or MAC address) to
access the Internet without prompting for a user name and password. This feature is useful, for
example, if you want to set up computers to provide free Internet access in the VIP room or for
sponsors in events.
To allow global access to web sites, specify the web site address (by IP address or URL) that any user
can access without logging in. This is similar to the walled garden feature, but without displaying the
web site link(s) in the subscriber login screen. You have to inform the users about which web sites
they can access for free.
11.2 Configuring Pass Through
To configure pass through on the ZyAIR, click ADVANCED and then PASS THROUGH.

DDNS
This chapter shows you how to set the ZyAIR to use DDNS.
15.1 About DDNS
DDNS (Dynamic Domain Name System) allows you to update your dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe or other
services). This is for cases where the ISP gives the ZyAIR a dynamic IP address but you still want to
use a domain name. You can also access your FTP server or Web site on your own computer using a
domain name (for example, myhost.dhs.org, where myhost is a name of your choice), which will never
change instead of using an IP address that changes each time you reconnect.
You must go to the Dynamic DNS service provider’s website
and register a user account and a domain name before you can use
the Dynamic DNS service with your ZyAIR.
The Dynamic DNS service provider will give you a password or key.
If you have a private WAN IP address, then you cannot use
Dynamic DNS.
15.1.1 DYNDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP
address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example,
www.yourhost.dyndns.org and still reach your hostname.

LAN Devices
This chapter describes how you can remotely access devices on the LAN through the ZyAIR.
16.1 LAN Devices and NAT 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.
Traditionally, when you have a device (for example, a switch) on a LAN using NAT, you cannot
access the device from the WAN since the LAN device is assigned a private IP address.
Your ZyAIR is a NAT-enabled device that makes your whole inside network appear as a single
computer to the outside world.
16.1.1 Port Mapping
To make LAN devices behind the ZyAIR visible to the outside world, you configure a mapping
between a virtual port on the ZyAIR and a server port on a LAN device. A virtual port is a port on the
ZyAIR that appears as a physical port to the attached devices. A server port defines a server to which
all specified requests are forwarded.
In addition, centralized LAN device management is possible through the ZyAIR using port mapping.
You can access the management interface on the LAN device remotely provided that the LAN device
has allowed remote management.
16.2 Configuring LAN Devices Port Mapping

In this example, there is a manageable switch and a wireless access point behind the ZyAIR and you
want to be able to remotely access the web-based management interfaces on the manageable switch
(on the left) and access point over the Internet.
Figure 16-2 LAN Device Remote Management Example 1
You map virtual port 60001 on the ZyAIR to the web server port on the access point and 60002 to the
web server port on the manageable switch.
Figure 16-3 LAN Devices: Example 1
To access the web-based management interface, enter the WAN IP address of your ZyAIR and the
virtual port number of the LAN device separated by a colon. In this example, to access the access
point (AP), enter “http:// 192.168.1.1:60001” where 192.168.1.1 is the WAN IP address of the ZyAIR.
The login screen of the LAN device management interface should display.
You can also access the LAN devices through the ZyAIR web configurator, refer to the section on
accessing the LAN devices for more information.

Chapter 18
Wireless LAN
This chapter shows you how to configure wireless LAN settings on the ZyAIR and set up
WEP encryption keys.
18.1 Wireless LAN Overview
This section introduces the wireless LAN (WLAN) and some basic scenarios.
18.1.1 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 and can set up an independent (wireless) network without the need of an access point (AP).
Figure 18-1 IBSS (Ad-hoc) Wireless LAN
18.1.2 BSS
A Basic Service Set (BSS) is 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.
Figure 18-2 Basic Service set
Wireless LAN
18-1
ZyAIR G-4100 User’s Guide
18.1.3 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.
Figure 18-3 Extended Service Set
18.2 Wireless LAN Basics
This section provides background information on Wireless LAN features.
18.2.1 Wireless Standards
The ZyAIR complies with the IEEE 802.11g wireless standard and is also fully compatible with the
802.11b standard. This means an IEEE 802.11b radio card can interface directly with an IEEE 802.11g
device (and vice versa) at 11 Mbps or lower depending on range.
The IEEE 802.11b data rate and corresponding modulation techniques are shown in the table below.
The modulation technique defines how bits are encoded onto radio waves.
Table 4 IEEE 802.11b Data Rates and Modulation
DATA RATE (MBPS)
MODULATION
1
DBPSK (Differential Binary Phase Shift Keyed)
2
DQPSK (Differential Quadrature Phase Shift Keying)
5.5 / 11
CCK (Complementary Code Keying)
IEEE 802.11g has several intermediate rate steps between the maximum and minimum data rates. The
IEEE 802.11g data rate and modulation are as follows:

DATA RATE (MBPS)

MODULATION
OFDM (Orthogonal Frequency Division Multiplexing)
The ZyAIR may be prone to RF (Radio Frequency) interference
from other 2.4 GHz devices such as microwave ovens, wireless
phones, Bluetooth enabled devices, and other wireless LANs.
18.2.2 Wireless LAN Coverage
The following table shows the ZyAIR’s coverage (in meters) using the included antennas. The
distance may differ depending on the network environment.
Table 18-6 Wireless LAN Coverage
≤11 Mbps
≤ 5.5 Mbps

80 m
Outdoor
200 m
300 m
18.2.3 Channel
A channel is the radio frequency(ies) used by IEEE 802.11g wireless devices. Channels available
depend on your geographical area. You may have a choice of channels (for your region) so you should
use a different channel than 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 and 11.
18.2.4 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. WPA
applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients
using an external RADIUS database. You can’t use the ZyAIR’s Local User Database for WPA
authentication purposes since the Local User Database uses EAP-MD5, which cannot be used to
generate keys.
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.
18.2.5 WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network.
WEP encryption scrambles the data transmitted between the wireless stations and the access points to
Wireless LAN
18-3
ZyAIR G-4100 User’s Guide
keep network communications private. It encrypts unicast and multicast communications in a network.
Both the wireless stations and the access points must use the same WEP key for data encryption and
decryption.
WEP degrades performance.
18.2.6 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 18-4 RTS/CTS
When station A sends data to the ZyAIR, 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.
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 (between 0 to 2432 bytes), 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.
18-4
Wireless LAN
ZyAIR G-4100 User’s Guide
Enabling the RTS Threshold causes redundant network
overhead that could negatively affect the throughput performance
instead of providing a remedy.
18.2.7 Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that
can be sent in the wireless network before the ZyAIR 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.
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.
18.3 Wireless LAN Setup

the wireless LAN and you change the ZyAIR’s ESSID or WEP
settings, you will lose your wireless connection when you press
Apply to confirm. You must then change the wireless settings of
your computer to match the ZyAIR’s new settings.

or
Enter 5 printable ASCII characters (case sensitive) ranging from “a-z”, “A-Z” and “09” (for example MyKey) for ASCII key type.
If you select 128 bit in the WEP Encryption field,
Enter either 26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (for example,
00112233445566778899AABBCC) for HEX key type
or
Enter 13 printable ASCII characters (case sensitive) ranging from “a-z”, “A-Z” and “09” (for example, MyKey12345678) for ASCII key type.
The values for the WEP keys must be set up
exactly the same on all wireless devices in the
same wireless LAN.
ASCII WEP keys are case sensitive.
Beacon Interval
Set the number of milliseconds that should pass between sending out a beacon. Enter a time
period between 1 and 1000. The default is 100.
RTS Threshold
Enter a value between 0 and 2442 to enable an RTS/CTS handshake to avoid retransmitting
due to hidden nodes. The default is 2432.
Fragmentation
Threshold
Enter a value between 256 and 2446 to enable a fragmentation threshold. This sets the
maximum size of data fragments that can be sent. The default is 2432. Use a low setting if
there is a great deal of radio interference.
Preamble Type
Preamble is used to signal that data is coming to the receiver.
Short preamble increases performance as less time sending preamble means more time for
sending data. All IEEE 802.11b compliant wireless adapters support long preamble, but not
all support short preamble.
Select Long Preamble if you are unsure what preamble mode the wireless adapters support,
and to provide more reliable communications in busy wireless networks. Select Short
Preamble if you are sure the wireless adapters support it, and to provide more efficient
communications.

Authentication
Method
DESCRIPTION
Select Open System to allow any device to authenticate and then attempt to communicate
with the ZyAIR. Using open authentication, any wireless device can authenticate with the
ZyAIR, but the device can only communicate if its WEP keys match the ZyAIR. Devices not
using WEP do not attempt to authenticate with a ZyAIR that is using WEP. Open
authentication does not rely on a RADIUS server on your network.
Select Shared Key to have the ZyAIR use shared key authentication. The ZyAIR sends an
unencrypted challenge text string to any device attempting to communicate with the ZyAIR.
The device-requesting authentication encrypts the challenge text and sends it back to the
ZyAIR. If the challenge text is encrypted correctly, the ZyAIR allows the requesting device to
authenticate. However, both the unencrypted challenge and the encrypted challenge can be
monitored; thus leaving the ZyAIR open to attack from an intruder who calculates the WEP
key by comparing the unencrypted and encrypted text strings. Because of this weakness,
shared key authentication can be less secure than open authentication. Like open
authentication, shared key authentication does not rely on a RADIUS server on your network.
Select Both to allow subscribers to communicate with or without data encryption.

Log Maintenance
This chapter shows you how to upgrade the firmware and configuration file and back up
configuration files and accounting logs.
20.1 Filename Conventions
The configuration file contains the factory default settings in the menus such as password, DHCP
Setup, TCP/IP Setup, etc. Once you have customized the settings of the ZyAIR, they can be saved
back to your computer under a filename of your choosing.
It is recommended to use the “.bin” file extension for the firmware file and “.rom” for the
configuration file for management purposes.
Visit www.zyxel.com to download the latest version of firmware for your ZyAIR.
20.2 Configuration File Maintenance
You can use the web configurator to perform configuration file backup and restore. Backing up the
configuration allows you to back up (save) the device’s current configuration to a file. Once your
device is configured and functioning properly, it is highly recommended that you back up your
configuration file before making configuration changes. The backup configuration file will be useful
in case you need to return to your previous settings.

IP Address Assignment Conflicts
This appendix describes situations where IP address conflicts may occur. Subscribers with duplicate IP
addresses will not be able to access the Internet.
Case A: The ZyAIR is Using the Same LAN and WAN IP Addresses
The following figure shows an example where the ZyAIR is using a WAN IP address that is the same
as the IP address of a computer on the LAN.
Diagram 1 IP Address Conflicts: Case A
You must set the ZyAIR to use different LAN and WAN IP addresses on different subnets if you
enable DHCP server on the ZyAIR. For example, you set the WAN IP address to 192.59.1.1 and the
LAN IP address to 10.59.1.1. Otherwise, It is recommended the ZyAIR use a public WAN IP address.
Case B: The ZyAIR LAN IP Address Conflicts with the DHCP Client
IP Address
In the following figure, the ZyAIR is acting as a DHCP server. The ZyAIR assigns an IP address,
which is the same as its LAN port IP address, to a DHCP client attached to the LAN.

Case D: Two or More Subscribers Have the Same IP Address.
By converting all private IP addresses to the WAN IP address, the ZyAIR allows subscribers with
different network configurations to access the Internet. However, there are situations where two or
more subscribers are using the same private IP address. This may happen when a subscriber is
configured to use a static (or fixed) IP address that is the same as the IP address the ZyAIR DHCP
server assigns to another subscriber acting as a DHCP client.
In this case, the subscribers are not able to access the Internet.

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. WLAN is not available on all models.
Benefits of a Wireless LAN
Wireless LAN offers the following benefits:
1. 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.
2. 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.
3. It allows flexible workgroups a lower total cost of ownership for workspaces that are frequently
reconfigured.
4. 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”.
5. 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. On September 16, 1999, the 802.11g
provided much higher data rates of up to 11Mbps, while maintaining the 802.11 protocol.
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.
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
L
Wireless LAN and IEEE 802.11
ZyAIR G-4100 User’s Guide
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). See the
following diagram of an example of an Ad-hoc wireless LAN.
Diagram 5 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.

Antenna Selection and Positioning
Recommendation
An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF 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 802.11g) 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.
•
•
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 transmitting and receiving antenna at the same height and in
a direct line of sight to each other to attend the best performance.
Antenna Selection and Positioning Recommendation
O
ZyAIR G-4100 User’s Guide
For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omnidirectional 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.
Connector Type
The ZyAIR is equipped with a reverse polarity SMA jack, so it will work with any 2.4GHz wireless
antenna with a reverse polarity SMA plug.

PPPoE
PPPoE in Action
An ADSL modem bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your PC
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:
1. It provides you with a familiar dial-up networking (DUN) user interface.
2. 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 & ISDN), the switching fabric is
already in place.
3.
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 PCs use traditional dial-up
networking.
Diagram 7 Single-PC per Modem Hardware Configuration
How PPPoE Works
The PPPoE driver makes the Ethernet appear as a serial link to the PC and the PC 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
PC and the ISP.
PPPoE
Q
ZyAIR G-4100 User’s Guide
ZyAIR as a PPPoE Client
When using the ZyAIR as a PPPoE client, the PCs 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
PCs.

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 PC 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 PC 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 PC 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.
Diagram 9 Transport PPP frames over Ethernet
PPTP and the ZyAIR
When the ZyAIR is deployed in such a setup, it appears as a PC 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 ZyAIR's Internet connection. In NAT mode, the
ZyAIR is able to pass the PPTP packets to the internal PPTP server (i.e. NT server) behind the NAT.
Users need to forward PPTP packets to port 1723 by configuring the server in Menu 15.2 - Server Set
Setup. In the case above as the remote PPTP Client initializes the PPTP connection, the user must
configure the PPTP clients. The ZyAIR initializes the PPTP connection hence; there is no need to
configure the remote PPTP clients.
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
PPTP
S
ZyAIR G-4100 User’s Guide
tunnels the PPP frames to the PNS. The PPTP user is unaware of the tunnel between the PAC and the
PNS.
Diagram 10 PPTP Protocol Overview
Microsoft includes PPTP as a part of the Windows OS. In Microsoft’s implementation, the PC, and
hence the ZyAIR, 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 PC and an
ANT.

IP Subnetting
IP Addressing
Routers “route” based on the network number. The router that delivers the data packet to the correct
destination host uses the host ID.
IP Classes
An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example,
192.168.1.1. IP addresses are categorized into different classes. The class of an address depends on the
value of its first octet.
Class “A” addresses have a 0 in the left most bit. In a class “A” address the first octet is the network number
and the remaining three octets make up the host ID.
Class “B” addresses have a 1 in the left most bit and a 0 in the next left most bit. In a class “B”
address the first two octets make up the network number and the two remaining octets make up the
host ID.
Class “C” addresses begin (starting from the left) with 1 1 0. In a class “C” address the first three
octets make up the network number and the last octet is the host ID.
Class “D” addresses begin with 1 1 1 0. Class “D” addresses are used for multicasting. (There is
also a class “E” address. It is reserved for future use.)

Therefore:
A class “C” network (8 host bits) can have 28 –2 or 254 hosts.
A class “B” address (16 host bits) can have 216 –2 or 65534 hosts.
A class “A” address (24 host bits) can have 224 –2 hosts (approximately 16 million hosts).
Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address
can have a value of 0 to 127.
Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B”
address has a valid range of 128 to 191. The first octet of a class “C” address begins with “110”, and
therefore has a range of 192 to 223.

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). A subnet mask has 32 bits; each bit of the mask
corresponds to a bit of the IP address. 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.
Subnet masks are expressed in dotted decimal notation just as IP addresses are. The “natural” masks
for class A, B and C IP addresses are as follows.
Chart 3 “Natural” Masks
CLASS
NATURAL MASK
A
255.0.0.0
B
255.255.0.0
C
255.255.255.0
Subnetting
With subnetting, the class arrangement of an IP address is ignored. For example, a class C address no
longer has to have 24 bits of network number and 8 bits of host ID. With subnetting, some of the host
ID bits are converted into network number bits. By convention, subnet masks always consist of a
continuous sequence of ones beginning from the left most bit of the mask, followed by a continuous
sequence of zeros, for a total number of 32 bits.
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 mask 255.255.255.128.
The following table shows all possible subnet masks for a class “C” address using both notations.

The first three octets of the address make up the network number (class “C”). You want to have two
separate networks.
Divide the network 192.168.1.0 into two separate subnets by converting one of the host ID bits of the
IP address to a network number bit. The “borrowed” host ID bit can be either “0” or “1” thus giving
two subnets; 192.168.1.0 with mask 255.255.255.128 and 192.168.1.128 with mask 255.255.255.128.
In the following charts, shaded/bolded last octet bit values
indicate host ID bits “borrowed” to form network ID bits. The
number of “borrowed” host ID bits determines the number of
subnets you can have. The remaining number of host ID bits (after
“borrowing”) determines the number of hosts you can have on
each subnet.

Lowest Host ID: 192.168.1.129
Broadcast Address: 192.168.1.255
Highest Host ID: 192.168.1.254
The remaining 7 bits determine the number of hosts each subnet can have. Host IDs of all zeros
represent the subnet itself and host IDs of all ones are the broadcast address for that subnet, so the
actual number of hosts available on each subnet in the example above is 27 – 2 or 126 hosts for each
subnet.
192.168.1.0 with mask 255.255.255.128 is the subnet itself, and 192.168.1.127 with mask
255.255.255.128 is the directed broadcast address for the first subnet. Therefore, the lowest IP address
that can be assigned to an actual host for the first subnet is 192.168.1.1 and the highest is
192.168.1.126. Similarly the host ID range for the second subnet is 192.168.1.129 to 192.168.1.254.
Example: Four Subnets
The above example illustrated using a 25-bit subnet mask to divide a class “C” address space into two
subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID
bits to give four possible combinations of 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 (all 0’s is the subnet itself, all 1’s is the broadcast address on
the subnet).

Subnetting With Class A and Class B Networks.
For class “A” and class “B” addresses the subnet mask also determines which bits are part of the
network number and which are part of the host ID.
A class “B” address has two host ID octets available for subnetting and a class “A” address has three
host ID octets (see Chart J-1) available for subnetting.
The following table is a summary for class “B” subnet planning.
