Introduction
1.1 Overview
The AMG1302/AMG1202-TSeries are ADSL2+ routers. By integrating DSL and NAT, you are
provided with ease of installation and high-speed, shared Internet access. The AMG1302/
AMG1202-TSeries are also a complete security solution with a robust firewall and content filtering.
Only use firmware for your AMG1302/AMG1202-TSeries’s specific model.
Refer to the label on the bottom of your AMG1302/AMG1202-TSeries.
Note: Not all models have all of the features shown in this User’s Guide.
1.2 Ways to Manage the AMG1302/AMG1202-TSeries
Use any of the following methods to manage the AMG1302/AMG1202-TSeries.
• Web Configurator. This is recommended for everyday management of the AMG1302/AMG1202TSeries using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP for firmware upgrades and configuration backup/restore.
• TR-069. This is an auto-configuration server used to remotely configure your device.
1.3 Good Habits for Managing the AMG1302/AMG1202TSeries
Do the following things regularly to make the AMG1302/AMG1202-TSeries more secure and to
manage the AMG1302/AMG1202-TSeries 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 AMG1302/AMG1202-TSeries to its factory
default settings. If you backed up an earlier configuration file, you would not have to totally reconfigure the AMG1302/AMG1202-TSeries. You could simply restore your last configuration.

1.4 Applications for the AMG1302/AMG1202-TSeries
Here are some example uses for which the AMG1302/AMG1202-TSeries is well suited.
1.4.1 Internet Access
Your AMG1302/AMG1202-TSeries provides shared Internet access by connecting the DSL port to
the DSL or MODEM jack on a splitter or your telephone jack. Computers can connect to the
AMG1302/AMG1202-TSeries’s Ethernet ports (or wirelessly).
Figure 1 AMG1302/AMG1202-TSeries’s Router Features
LAN
WAN
DSL
You can also configure firewall and filtering feature on the AMG1302/AMG1202-TSeries for secure
Internet access. When the firewall is on, all incoming traffic from the Internet to your network is
blocked unless it is initiated from your network. This means that probes from the outside to your
network are not allowed, but you can safely browse the Internet and download files.
Use the filtering feature to block access to specific web sites or Internet applications such as MSN or
Yahoo Messenger. You can also configure IP/MAC filtering rules for incoming or outgoing traffic.
Use QoS to efficiently manage traffic on your network by giving priority to certain types of traffic
and/or to particular computers. For example, you could make sure that the AMG1302/AMG1202TSeries gives voice over Internet calls high priority, and/or limit bandwidth devoted to the boss’s
excessive file downloading.
1.4.2 Wireless Access
The ZyXEL Device is a wireless Access Point (AP) for IEEE 802.11b/g/n compliant clients, such as
notebook computers or PDAs and iPads. It allows them to connect to the Internet without having to
rely on inconvenient Ethernet cables. You can set up a wireless network with WPS (WiFi Protected
Setup) or manually add a client to your wireless network.

AMG1202-TSeries as the AP and ZyXEL NWD210N as the wireless client which connects to the
notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter
or PCMCIA card).
There are two WPS methods to set up the wireless client settings:
• Push Button Configuration (PBC) - simply press a button. This is the easier of the two
methods.
• PIN Configuration - configure a Personal Identification Number (PIN) on the AMG1302/
AMG1202-TSeries. A wireless client must also use the same PIN in order to download the wireless
network settings from the AMG1302/AMG1202-TSeries.
Push Button Configuration (PBC)
Make sure that your AMG1302/AMG1202-TSeries is turned on and your notebook is within the cover
range of the wireless signal.
Make sure that you have installed the wireless client driver and utility in your notebook.
Make sure wireless LAN is enabled and the wireless security mode is set to WPA-PSK2 or No
Security in the Network Setting > Wireless > General screen.
In the wireless client utility, go to the WPS setting page. Enable WPS and press the WPS button
(Start or WPS button).
Push and hold the WPS button on the AMG1302/AMG1202-TSeries for 1-2 seconds. Alternatively,
you may log into AMG1302/AMG1202-TSeries’s web configuration, enable WPS and click the WPS
button in the Network Setting > Wireless > WPS screen.
Note: It doesn’t matter which button (on the client or the AMG1302/AMG1202-TSeries) is
pressed first. You must press the second button within two minutes of pressing the
first one.
The AMG1302/AMG1202-TSeries sends the proper configuration settings to the wireless client. This
may take up to two minutes. The wireless client is then able to communicate with the AMG1302/
AMG1202-TSeries securely.

4.8 Configuring Static Route for Routing to Another
Network
In order to extend your Intranet and control traffic flowing directions, you may connect a router to
the AMG1302/AMG1202-TSeries’s LAN. The router may be used to separate two department
networks. This tutorial shows how to configure a static routing rule for two network routings.
In the following figure, router R is connected to the AMG1302/AMG1202-TSeries’s LAN. R connects
to two networks, N1 (192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from
computer A (in N1 network) to computer B (in N2 network), the traffic is sent to the AMG1302/
AMG1202-TSeries’s WAN default gateway by default. In this case, B will never receive the traffic.
N1
N2
You need to specify a static routing rule on the AMG1302/AMG1202-TSeries to specify R as the
router in charge of forwarding traffic to N2. In this case, the AMG1302/AMG1202-TSeries routes
traffic from A to R and then R routes the traffic to B.

4.9 Port Binding Configuration
This tutorial shows you how to configure port binding for WAN connections with different ATM QoS
settings for different types of traffic. The port binding feature is used to group each WAN connection
with specific LAN ports and WLANs. In this example ATM QoS settings are configured for a WAN PVC
for time sensitive Media-On-Demand (MOD) traffic. ATM QoS settings are also configured for
another WAN PVC for non-time sensitive data traffic.
4.9.1 Configuring ATM QoS for Multiple WAN Connections
This example shows an application for multiple WAN connections with different ATM QoS Settings.
More than one WAN connection on the AMG1302/AMG1202-TSeries may be configured to record
traffic statistics or calculate service charges.
Three WAN connections are configured over the ADSL line:
• The connection with VPI/VCI, 0/33, is dedicated for general data transmission.
• The connection with VPI/VCI, 0/34, is dedicated for VoIP service.
• The connection with VPI/VCI, 0/35, is dedicated for Media-On-Demand (MOD) service.
To configure bandwidth for the WAN connections, access the WAN configuration Advanced Setup

4.10 Configuring QoS to Prioritize Traffic
This section contains tutorials on how you can configure the QoS screen.
Let’s say you are a team leader of a small sales branch office. You want to prioritize e-mail traffic
because your task includes sending urgent updates to clients at least twice every hour. You also
upload data files (such as logs and e-mail archives) to the FTP server throughout the day. Your
colleagues use the Internet for research, as well as chat applications for communicating with other
branch offices.
In the following figure you want to configure QoS so that e-mail traffic gets the highest priority. You
can do the following:
• Configure a queue to assign the highest priority queue (1) to e-mail traffic from the LAN
interface, so that e-mail traffic would not get delayed when there is network congestion.
• Note the MAC address (AA:FF:AA:FF:AA:FF for example) of your computer and map it to queue
1.
Note: QoS is applied to traffic flowing out of the AMG1302/AMG1202-TSeries.
Traffic that does not match this class is assigned a priority queue based on the internal QoS
mapping table on the AMG1302/AMG1202-TSeries.

6.1 Overview
This chapter describes the AMG1302/AMG1202-TSeries’s Broadband screens. Use these screens to
configure your AMG1302/AMG1202-TSeries for Internet access.
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.

6.1.1 What You Can Do in the WAN Screens
• Use the Internet Connection screen (Section 6.2 on page 74) to configure the WAN settings on
the AMG1302/AMG1202-TSeries for Internet access.
• Use the More Connections screen (Section 6.3 on page 81) to set up additional Internet access
connections.
6.1.2 What You Need to Know About WAN
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 PPPoA, 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 AMG1302/AMG1202-TSeries, which makes it accessible
from an outside network. It is used by the AMG1302/AMG1202-TSeries to communicate with other
AMG1302/AMG1202-TSeries User’s Guide
73
Chapter 6 Broadband
devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the
AMG1302/AMG1202-TSeries 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).
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 one.
IGMP
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. There are three versions of IGMP. IGMP
version 2 and 3 are improvements over version 1, but IGMP version 1 is still in wide use.
IPv6
IPv6 (Internet Protocol version 6), is designed to increase IP address space and enhance features.
The AMG1302/AMG1202-TSeries supports IPv4/IPv6 dual stack and can connect to IPv4 and IPv6
networks. See (Appendix E on page 295) for more information about IPv6.
Finding Out More
See Section 6.4 on page 86 for technical background information on WAN.

6.4 WAN Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
6.4.1 Encapsulation
Be sure to use the encapsulation method required by your ISP. The AMG1302/AMG1202-TSeries
supports the following methods.
6.4.1.1 ENET ENCAP
The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP
network protocol. IP packets are routed between the Ethernet interface and the WAN interface and
then formatted so that they can be understood in a bridged environment. For instance, it
encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP requires that you specify
a gateway IP address in the Gateway IP Address field in the wizard or WAN screen. You can get
this information from your ISP.
6.4.1.2 PPP over Ethernet
The AMG1302/AMG1202-TSeries supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is
an IETF Draft standard (RFC 2516) specifying how a personal computer (PC) interacts with a
broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE 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 AMG1302/AMG1202-TSeries (rather than individual
computers), the computers on the LAN do not need PPPoE software installed, since the AMG1302/
86
AMG1302/AMG1202-TSeries User’s Guide
Chapter 6 Broadband
AMG1202-TSeries does that part of the task. Furthermore, with NAT, all of the LANs’ computers will
have access.
6.4.1.3 PPPoA
PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection
functions like a dial-up Internet connection. The AMG1302/AMG1202-TSeries encapsulates the PPP
session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the
Internet Service Provider’s (ISP) DSLAM (Digital Subscriber Line (DSL) Access Multiplexer). Please
refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP.
6.4.1.4 RFC 1483
RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5
(AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit
(LLC-based multiplexing) and the second method assumes that each protocol is carried over a
separate ATM virtual circuit (VC-based multiplexing). Please refer to RFC 1483 for more detailed
information.
6.4.2 Multiplexing
There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to
use the multiplexing method required by your ISP.
VC-based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for
example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where
dynamic creation of large numbers of ATM VCs is fast and economical.
LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information being contained
in each packet header. Despite the extra bandwidth and processing overhead, this method may be
advantageous if it is not practical to have a separate VC for each carried protocol, for example, if
charging heavily depends on the number of simultaneous VCs.
6.4.3 VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers
assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is
reserved for local management of ATM traffic). Please see the appendix for more information.
6.4.4 IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a
different one each time. The Single User Account feature can be enabled or disabled if you have
either a dynamic or static IP. However the encapsulation method assigned influences your choices
for IP address and ENET ENCAP gateway.
AMG1302/AMG1202-TSeries User’s Guide
87
Chapter 6 Broadband
IP Assignment with PPPoA or PPPoE Encapsulation
If you have a dynamic IP, then the IP Address and Gateway IP Address fields are not applicable
(N/A). If you have a Static IP Address assigned by your ISP, then they should also assign you a
Subnet Mask and a Gateway IP Address.
IP Assignment with RFC 1483 Encapsulation
In this case the IP address assignment must be static.
IP Assignment with ENET ENCAP Encapsulation
In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP
Address and Gateway IP Address fields as supplied by your ISP. However for a dynamic IP, the
AMG1302/AMG1202-TSeries acts as a DHCP client on the WAN port and so the IP Address and
Gateway IP Address fields are not applicable (N/A) as the DHCP server assigns them to the
AMG1302/AMG1202-TSeries.
6.4.5 Nailed-Up Connection (PPP)
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic
demand. The AMG1302/AMG1202-TSeries does two things when you specify a nailed-up
connection. The first is that idle timeout is disabled. The second is that the AMG1302/AMG1202TSeries will try to bring up the connection when turned on and whenever the connection is down. A
nailed-up connection can be very expensive for obvious reasons.
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you
need a constant connection and the cost is of no concern.
6.4.6 NAT
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 to a
different IP address known within another network.
6.5 Traffic Shaping
Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate
and fluctuations of data transmission over an ATM network. This agreement helps eliminate
congestion, which is important for transmission of real time data such as audio and video
connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may
be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a
maximum speed of 832Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed
because it is dependent on the line speed.
88
AMG1302/AMG1202-TSeries User’s Guide
Chapter 6 Broadband
Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It specifies the
maximum average rate at which cells can be sent over the virtual connection. SCR may not be
greater than the PCR.
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS
is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more
cells (up to the MBS) can be sent at the PCR again.
If the PCR, SCR or MBS is set to the default of "0", the system will assign a maximum value that
correlates to your upstream line rate.
The following figure illustrates the relationship between PCR, SCR and MBS.
Figure 26 Example of Traffic Shaping
6.5.1 ATM Traffic Classes
These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0
Specification.
Constant Bit Rate (CBR)
Constant Bit Rate (CBR) provides fixed bandwidth that is always available even if no data is being
sent. CBR traffic is generally time-sensitive (doesn't tolerate delay). CBR is used for connections
that continuously require a specific amount of bandwidth. A PCR is specified and if traffic exceeds
this rate, cells may be dropped. Examples of connections that need CBR would be high-resolution
video and voice.
Variable Bit Rate (VBR)
The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections. Connections that use
the Variable Bit Rate (VBR) traffic class can be grouped into real time (VBR-RT) or non-real time
(VBR-nRT) connections.
The VBR-RT (real-time Variable Bit Rate) type is used with bursty connections that require closely
controlled delay and delay variation. It also provides a fixed amount of bandwidth (a PCR is
specified) but is only available when data is being sent. An example of an VBR-RT connection would
be video conferencing. Video conferencing requires real-time data transfers and the bandwidth
requirement varies in proportion to the video image's changing dynamics.
AMG1302/AMG1202-TSeries User’s Guide
89
Chapter 6 Broadband
The VBR-nRT (non real-time Variable Bit Rate) type is used with bursty connections that do not
require closely controlled delay and delay variation. It is commonly used for "bursty" traffic typical
on LANs. PCR and MBS define the burst levels, SCR defines the minimum level. An example of an
VBR-nRT connection would be non-time sensitive data file transfers.
Unspecified Bit Rate (UBR)
The Unspecified Bit Rate (UBR) ATM traffic class is for bursty data transfers. However, UBR doesn't
guarantee any bandwidth and only delivers traffic when the network has spare bandwidth. An
example application is background file transfer.

7.1.2 What You Need to Know About Wireless
Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send and
receive information over the airwaves, wireless networking devices exchange information with one
another. A wireless networking device is just like a radio that lets your computer exchange
information with radios attached to other computers. Like walkie-talkies, most wireless networking
devices operate at radio frequency bands that are open to the public and do not require a license to
use. However, wireless networking is different from that of most traditional radio communications in
that there a number of wireless networking standards available with different methods of data
encryption.
Finding Out More
See Section 7.10 on page 107 for advanced technical information on wireless networks.
7.1.3 Before You Start
Before you start using these screens, ask yourself the following questions. See Section 7.1.2 on
page 92 if some of the terms used here are not familiar to you.
• What wireless standards do the other wireless devices in your network support (IEEE 802.11g,
for example)? What is the most appropriate standard to use?
• What security options do the other wireless devices in your network support (WPA-PSK, for
example)? What is the strongest security option supported by all the devices in your network?
• Do the other wireless devices in your network support WPS (Wi-Fi Protected Setup)? If so, you
can set up a well-secured network very easily.
Even if some of your devices support WPS and some do not, you can use WPS to set up your
network and then add the non-WPS devices manually, although this is somewhat more
complicated to do.
• What advanced options do you want to configure, if any? If you want to configure advanced
options such as Quality of Service, ensure that you know precisely what you want to do. If you do
not want to configure advanced options, leave them as they are.
7.2 The General Screen

Figure 28 Wireless > General: No Security
7.2.2 Basic (WEP Encryption)
WEP encryption scrambles the data transmitted between the wireless stations and the access points
(AP) to keep network communications private. Both the wireless stations and the access points
must use the same WEP key.
Note: WEP is extremely insecure. Its encryption can be broken by an attacker, using
widely-available software. It is strongly recommended that you use a more
effective security mechanism. Use the strongest security mechanism that all the
wireless devices in your network support. For example, use WPA-PSK or WPA2-PSK
if all your wireless devices support it, or use WPA or WPA2 if your wireless devices
support it and you have a RADIUS server. If your wireless devices support nothing
stronger than WEP, use the highest encryption level available.
Your AMG1302/AMG1202-TSeries allows you to configure one 64-bit or 128-bit WEP key.

Password
The password (WEP key) are used to encrypt data. Both the AMG1302/AMG1202-TSeries
and the wireless stations must use the same password (WEP key) for data transmission.
If you chose 64-bit WEP, then enter any 5 ASCII characters or 10 hexadecimal characters
("0-9", "A-F").
If you chose 128-bit WEP, then enter 13 ASCII characters or 26 hexadecimal characters
("0-9", "A-F").
WEP Encryption
Select 64-bits or 128-bits.
This dictates the length of the security key that the network is going to use.
7.2.3 More Secure (WPA(2)-PSK)
The WPA-PSK security mode provides both improved data encryption and user authentication over
WEP. Using a Pre-Shared Key (PSK), both the AMG1302/AMG1202-TSeries and the connecting
client share a common password in order to validate the connection. This type of encryption, while
robust, is not as strong as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode is a
newer, more robust version of the WPA encryption standard. It offers slightly better security,
although the use of PSK makes it less robust than it could be.

7.2.4 WPA(2) Authentication
The WPA2 security mode is currently the most robust form of encryption for wireless networks. It
requires a RADIUS server to authenticate user credentials and is a full implementation the security
protocol. Use this security option for maximum protection of your network. However, it is the least
backwards compatible with older devices.
96
AMG1302/AMG1202-TSeries User’s Guide

7.6 The WDS Screen
An AP using the Wireless Distribution System (WDS) can function as a wireless network bridge
allowing you to wirelessly connect wired network segments. The WDS screen allows you to
configure the AMG1302/AMG1202-TSeries to connect to other APs wirelessly when WDS is enabled.
Use this screen to set up your WDS (Wireless Distribution System) links between the AMG1302/
AMG1202-TSeries and other wireless APs. You need to know the MAC address of the peer device.
Once the security settings of peer sides match one another, the connection between devices is
made.
Note: WDS security is independent of the security settings between the AMG1302/
AMG1202-TSeries and any wireless clients.

A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a 40MHz
channel uses two standard channels and offers speeds of up to 300 Mbps.
40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. The wireless clients must also support 40 MHz. It is often better to use the 20
MHz setting in a location where the environment hinders the wireless signal.
Select 20MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.

7.10 Wireless LAN Technical Reference
This section discusses wireless LANs in depth. For more information, see the appendix.
7.10.1 Wireless Network Overview
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can connect with
numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and wireless clients,
extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
AMG1302/AMG1202-TSeries User’s Guide
107
Chapter 7 Wireless LAN
• An “infrastructure” type of network has one or more access points and one or more wireless
clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless clients connect to
one another in order to exchange information.
The following figure provides an example of a wireless network.
Figure 40 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B use the
access point (AP) to interact with the other devices (such as the printer) or with the Internet. Your
AMG1302/AMG1202-TSeries is the AP.
Every wireless network must follow these basic guidelines.
• Every device in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentifier.
• If two wireless networks overlap, they should use a different channel.
Like radio stations or television channels, each wireless network uses a specific channel, or
frequency, to send and receive information.
• Every device 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.
Radio Channels
In the radio spectrum, there are certain frequency bands allocated for unlicensed, civilian use. For
the purposes of wireless networking, these bands are divided into numerous channels. This allows a
108
AMG1302/AMG1202-TSeries User’s Guide
Chapter 7 Wireless LAN
variety of networks to exist in the same place without interfering with one another. When you
create a network, you must select a channel to use.
Since the available unlicensed spectrum varies from one country to another, the number of
available channels also varies.

DESCRIPTION
Preamble
A preamble affects the timing in your wireless network. There are two preamble
modes: long and short. If a device uses a different preamble mode than the
AMG1302/AMG1202-TSeries does, it cannot communicate with the AMG1302/
AMG1202-TSeries.
Authentication
The process of verifying whether a wireless device is allowed to use the wireless
network.
Fragmentation
Threshold
A small fragmentation threshold is recommended for busy networks, while a larger
threshold provides faster performance if the network is not very busy.
7.10.3 Wireless Security Overview
By their nature, radio communications are simple to intercept. For wireless data networks, this
means that anyone within range of a wireless network without security can not only read the data
passing over the airwaves, but also join the network. Once an unauthorized person has access to
the network, he or she can steal information or introduce malware (malicious software) intended to
compromise the network. For these reasons, a variety of security systems have been developed to
ensure that only authorized people can use a wireless data network, or understand the data carried
on it.
These security standards do two things. First, they authenticate. This means that only people
presenting the right credentials (often a username and password, or a “key” phrase) can access the
network. Second, they encrypt. This means that the information sent over the air is encoded. Only
people with the code key can understand the information, and only people who have been
authenticated are given the code key.
These security standards vary in effectiveness. Some can be broken, such as the old Wired
Equivalent Protocol (WEP). Using WEP is better than using no security at all, but it will not keep a
determined attacker out. Other security standards are secure in themselves but can be broken if a
user does not use them properly. For example, the WPA-PSK security standard is very secure if you
use a long key which is difficult for an attacker’s software to guess - for example, a twenty-letter
long string of apparently random numbers and letters - but it is not very secure if you use a short
key which is very easy to guess - for example, a three-letter word from the dictionary.
Because of the damage that can be done by a malicious attacker, it’s not just people who have
sensitive information on their network who should use security. Everybody who uses any wireless
network should ensure that effective security is in place.
A good way to come up with effective security keys, passwords and so on is to use obscure
information that you personally will easily remember, and to enter it in a way that appears random
and does not include real words. For example, if your mother owns a 1970 Dodge Challenger and
AMG1302/AMG1202-TSeries User’s Guide
109
Chapter 7 Wireless LAN
her favorite movie is Vanishing Point (which you know was made in 1971) you could use
“70dodchal71vanpoi” as your security key.
The following sections introduce different types of wireless security you can set up in the wireless
network.
7.10.3.1 SSID
Normally, the AMG1302/AMG1202-TSeries acts like a beacon and regularly broadcasts the SSID in
the area. You can hide the SSID instead, in which case the AMG1302/AMG1202-TSeries 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 wireless
devices to get the SSID. In addition, unauthorized wireless devices can still see the information that
is sent in the wireless network.
7.10.3.2 MAC Address Filter
Every device that can use a wireless network has a unique identification number, called a MAC
address.1 A MAC address is usually written using twelve hexadecimal characters2; for example,
00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each device in the wireless
network, see the device’s User’s Guide or other documentation.
You can use the MAC address filter to tell the AMG1302/AMG1202-TSeries which devices are
allowed or not allowed to use the wireless network. If a device is allowed to use the wireless
network, it still has to have the correct information (SSID, channel, and security). If a device is not
allowed to use the wireless network, it does not matter if it has the correct information.
This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized wireless devices to get the MAC address of an
authorized device. Then, they can use that MAC address to use the wireless network.
7.10.3.3 User Authentication
Authentication is the process of verifying whether a wireless device is allowed to use the wireless
network. You can make every user log in to the wireless network before using it. However, every
device in the wireless network has to support IEEE 802.1x to do this.
For wireless networks, you can store the user names and passwords for each user in a RADIUS
server. This is a server used in businesses more than in homes. If you do not have a RADIUS server,
you cannot set up user names and passwords for your users.
Unauthorized wireless devices can still see the information that is sent in the wireless network,
even if they cannot use the wireless network. Furthermore, there are ways for unauthorized
wireless users to get a valid user name and password. Then, they can use that user name and
password to use the wireless network.

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.

AMG1302/AMG1202-TSeries User’s Guide
Chapter 7 Wireless LAN
7.10.3.4 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 authentication. (See Section
7.10.3.3 on page 110 for information about this.)
Table 29 Types of Encryption for Each Type of Authentication
Weakest
NO AUTHENTICATION
RADIUS SERVER
No Security
WPA
Static WEP
WPA-PSK
Strongest
WPA2-PSK
WPA2
For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users
do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or
WPA2-PSK.
Usually, you should set up the strongest encryption that every device in the wireless network
supports. For example, suppose you have a wireless network with the AMG1302/AMG1202-TSeries
and you do not have a RADIUS server. Therefore, there is no authentication. Suppose the wireless
network has two devices. Device A only supports WEP, and device B supports WEP and WPA-PSK.
Therefore, you should set up Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. The other types of encryption are better than none at all, but it is still
possible for unauthorized wireless devices to figure out the original information
pretty quickly.
When you select WPA2 or WPA2-PSK in your AMG1302/AMG1202-TSeries, you can also select an
option (WPA compatible) to support WPA as well. In this case, if some of the devices support WPA
and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of
wireless network login) and select the WPA compatible option in the AMG1302/AMG1202-TSeries.
Many types of encryption use a key to protect the information in the wireless network. The longer
the key, the stronger the encryption. Every device in the wireless network must have the same key.
7.10.4 Signal Problems
Because wireless networks are radio networks, their signals are subject to limitations of distance,
interference and absorption.
Problems with distance occur when the two radios are too far apart. Problems with interference
occur when other radio waves interrupt the data signal. Interference may come from other radio
transmissions, such as military or air traffic control communications, or from machines that are
coincidental emitters such as electric motors or microwaves. Problems with absorption occur when
physical objects (such as thick walls) are between the two radios, muffling the signal.
AMG1302/AMG1202-TSeries User’s Guide

Chapter 7 Wireless LAN
7.10.5 BSS
A Basic Service Set (BSS) exists when all communications between wireless stations or between a
wireless station and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS traffic blocking is
disabled, wireless station A and B can access the wired network and communicate with each other.
When Intra-BSS traffic blocking is enabled, wireless station A and B can still access the wired
network but cannot communicate with each other.
Figure 41 Basic Service set
7.10.6 MBSSID
Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well
as the cost of buying extra APs, there is also the possibility of channel interference. The AMG1302/
AMG1202-TSeries’s MBSSID (Multiple Basic Service Set IDentifier) function allows you to use one
access point to provide several BSSs simultaneously. You can then assign varying QoS priorities
and/or security modes to different SSIDs.
Wireless devices can use different BSSIDs to associate with the same AP.
7.10.6.1 Notes on Multiple BSSs
• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use different keys for different BSSs. If two wireless devices have different BSSIDs
(they are in different BSSs), but have the same keys, they may hear each other’s
communications (but not communicate with each other).
112
AMG1302/AMG1202-TSeries User’s Guide
Chapter 7 Wireless LAN
• MBSSID should not replace but rather be used in conjunction with 802.1x security.
7.10.7 Wireless Distribution System (WDS)
The AMG1302/AMG1202-TSeries can act as a wireless network bridge and establish WDS (Wireless
Distribution System) links with other APs. You need to know the MAC addresses of the APs you want
to link to. Once the security settings of peer sides match one another, the connection between
devices is made.
At the time of writing, WDS security is compatible with other ZyXEL access points only. Refer to
your other access point’s documentation for details.
The following figure illustrates how WDS link works between APs. Notebook computer A is a
wireless client connecting to access point AP 1. AP 1 has no wired Internet connection, but it can
establish a WDS link with access point AP 2, which has a wired Internet connection. When AP 1
has a WDS link with AP 2, the notebook computer can access the Internet through AP 2.
Figure 42 WDS Link Example

7.10.8 WiFi Protected Setup (WPS)
Your AMG1302/AMG1202-TSeries 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.
7.10.8.1 Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled
device, and allowing them to connect automatically. You do not need to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in
their configuration utilities instead of or in addition to the physical button.
Take the following steps to set up WPS using the button.
Ensure that the two devices you want to set up are within wireless range of one another.
AMG1302/AMG1202-TSeries User’s Guide
113
Chapter 7 Wireless LAN
Look for a WPS button on each device. If the device does not have one, log into its configuration
utility and locate the button (see the device’s User’s Guide for how to do this - for the AMG1302/
AMG1202-TSeries, see Section 7.6 on page 103).
Press the button on one of the devices (it doesn’t matter which). For the AMG1302/AMG1202TSeries you must press the WPS button for more than three seconds.
Within two minutes, press the button on the other device. The registrar sends the network name
(SSID) and security key through an secure connection to the enrollee.
If you need to make sure that WPS worked, check the list of associated wireless clients in the AP’s
configuration utility. If you see the wireless client in the list, WPS was successful.
7.10.8.2 PIN Configuration
Each WPS-enabled device has its own PIN (Personal Identification Number). This may either be
static (it cannot be changed) or dynamic (in some devices you can generate a new PIN by clicking
on a button in the configuration interface).
Use the PIN method instead of the push-button configuration (PBC) method if you want to ensure
that the connection is established between the devices you specify, not just the first two devices to
activate WPS in range of each other. However, you need to log into the configuration interfaces of
both devices to use the PIN method.
When you use the PIN method, you must enter the PIN from one device (usually the wireless client)
into the second device (usually the Access Point or wireless router). Then, when WPS is activated
on the first device, it presents its PIN to the second device. If the PIN matches, one device sends
the network and security information to the other, allowing it to join the network.
Take the following steps to set up a WPS connection between an access point or wireless router
(referred to here as the AP) and a client device using the PIN method.
Ensure WPS is enabled on both devices.
Access the WPS section of the AP’s configuration interface. See the device’s User’s Guide for how to
do this.
Look for the client’s WPS PIN; it will be displayed either on the device, or in the WPS section of the
client’s configuration interface (see the device’s User’s Guide for how to find the WPS PIN - for the
AMG1302/AMG1202-TSeries, see Section 7.5 on page 101).
Enter the client’s PIN in the AP’s configuration interface.
If the client device’s configuration interface has an area for entering another device’s PIN, you can
either enter the client’s PIN in the AP, or enter the AP’s PIN in the client - it does not matter which.
Start WPS on both devices within two minutes.
Use the configuration utility to activate WPS, not the push-button on the device itself.
On a computer connected to the wireless client, try to connect to the Internet. If you can connect,
WPS was successful.
If you cannot connect, check the list of associated wireless clients in the AP’s configuration utility. If
you see the wireless client in the list, WPS was successful.

7.10.8.3 How WPS Works
When two WPS-enabled devices connect, each device must assume a specific role. One device acts
as the registrar (the device that supplies network and security settings) and the other device acts
as the enrollee (the device that receives network and security settings. The registrar creates a
secure EAP (Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the
WPA2-PSK pre-shared key to the enrollee. If the registrar is already part of a network, it sends the
existing information. If not, it generates the SSID and WPA2)-PSK randomly.
The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a
WPS-enabled access point.

SECURITY INFO
COMMUNICATION
The roles of registrar and enrollee last only as long as the WPS setup process is active (two
minutes). The next time you use WPS, a different device can be the registrar if necessary.
The WPS connection process is like a handshake; only two devices participate in each WPS
transaction. If you want to add more devices you should repeat the process with one of the existing
networked devices and the new device.
Note that the access point (AP) is not always the registrar, and the wireless client is not always the
enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless clients.
By default, a WPS devices is “unconfigured”. This means that it is not part of an existing network
and can act as either enrollee or registrar (if it supports both functions). If the registrar is
unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once a
WPS-enabled device has connected to another device using WPS, it becomes “configured”. A
configured wireless client can still act as enrollee or registrar in subsequent WPS connections, but a
configured access point can no longer act as enrollee. It will be the registrar in all subsequent WPS
connections in which it is involved. If you want a configured AP to act as an enrollee, you must reset
it to its factory defaults.
7.10.8.4 Example WPS Network Setup
This section shows how security settings are distributed in an example WPS setup.
The following figure shows an example network. In step 1, both AP1 and Client 1 are
unconfigured. When WPS is activated on both, they perform the handshake. In this example, AP1
is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security
information to set up the network, since it is unconfigured and has no existing information.

In step 2, you add another wireless client to the network. You know that Client 1 supports registrar
mode, but it is better to use AP1 for the WPS handshake with the new client since you must
connect to the access point anyway in order to use the network. In this case, AP1 must be the
registrar, since it is configured (it already has security information for the network). AP1 supplies
the existing security information to Client 2.

2 supports the registrar function, so you use it to perform the WPS handshake instead.

7.10.8.5 Limitations of WPS
WPS has some limitations of which you should be aware.
• WPS works in Infrastructure networks only (where an AP and a wireless client communicate). It
does not work in Ad-Hoc networks (where there is no AP).
• When you use WPS, it works between two devices only. You cannot enroll multiple devices
simultaneously, you must enroll one after the other.
For instance, if you have two enrollees and one registrar you must set up the first enrollee (by
pressing the WPS button on the registrar and the first enrollee, for example), then check that it
successfully enrolled, then set up the second device in the same way.
• WPS works only with other WPS-enabled devices. However, you can still add non-WPS devices to
a network you already set up using WPS.
WPS works by automatically issuing a randomly-generated WPA2-PSK pre-shared key from the
registrar device to the enrollee devices. You can check the configuration interface of the registrar
device to discover the key the network is using (if the device supports this feature). Then, you
can enter the key into the non-WPS device and join the network as normal (the non-WPS device
must also support WPA2-PSK).
• When you use the PBC method, there is a short period (from the moment you press the button
on one device to the moment you press the button on the other device) when any WPS-enabled
device could join the network. This is because the registrar has no way of identifying the
“correct” enrollee, and cannot differentiate between your enrollee and a rogue device. This is a
possible way for a hacker to gain access to a network.
You can easily check to see if this has happened. WPS works between only two devices
simultaneously, so if another device has enrolled your device will be unable to enroll, and will not
have access to the network. If this happens, open the access point’s configuration interface and
look at the list of associated clients (usually displayed by MAC address). It does not matter if the

Chapter 7 Wireless LAN
access point is the WPS registrar, the enrollee, or was not involved in the WPS handshake; a
rogue device must still associate with the access point to gain access to the network. Check the
MAC addresses of your wireless clients (usually printed on a label on the bottom of the device). If
there is an unknown MAC address you can remove it or reset the AP.

8.1 Overview
A Local Area Network (LAN) is a shared communication system to which many networking devices
are connected. It is usually located in one immediate area such as a building or floor of a building.
Use the LAN screens to help you configure a LAN DHCP server and manage IP addresses.
LAN
DSL
8.1.1 What You Can Do in the LAN Screens
• Use the LAN Setup screen to set the LAN IP address, subnet mask, and DHCP settings of your
AMG1302/AMG1202-TSeries (Section 8.2 on page 123).
• Use the Static DHCP screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 8.3 on page 125).
• Use the UPnP screen to enable UPnP and UPnP NAT traversal on the AMG1302/AMG1202-TSeries
(Section 8.4 on page 126).
• Use the IP Alias screen (Section 8.5 on page 126) to change your AMG1302/AMG1202-TSeries’s
IP alias settings.
• Use the IPv6 LAN Setup screen (Section 8.6 on page 127) to configure the IPv6 settings on
your AMG1302/AMG1202-TSeries’s LAN interface.
8.1.2 What You Need To Know
8.1.2.1 About LAN
IP Address
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.
AMG1302/AMG1202-TSeries User’s Guide
121
Chapter 8 Home Networking
Subnet Mask
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.
DHCP
A DHCP (Dynamic Host Configuration Protocol) server can assign your AMG1302/AMG1202-TSeries
an IP address, subnet mask, DNS and other routing information when it's turned on.
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 networking device before you can access it.
8.1.2.2 About UPnP
Identifying UPnP Devices
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.
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 Chapter 11 on page 151 for more information on NAT.
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 AMG1302/AMG1202-TSeries 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.

8.7 Home Networking Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
8.7.1 LANs, WANs and the AMG1302/AMG1202-TSeries
The actual physical connection determines whether the AMG1302/AMG1202-TSeries 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 54 LAN and WAN IP Addresses
LAN
WAN
8.7.2 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the AMG1302/AMG1202TSeries as a DHCP server or disable it. When configured as a server, the AMG1302/AMG1202TSeries provides the TCP/IP configuration for the clients. If you turn DHCP service off, you must
have another DHCP server on your LAN, or else the computer must be manually configured.
IP Pool Setup
The AMG1302/AMG1202-TSeries is pre-configured with a pool of IP addresses for the DHCP clients
(DHCP Pool). Do not assign static IP addresses from the DHCP pool to your LAN computers.
8.7.3 DNS Server Addresses
DNS (Domain Name System) maps 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 DNS server addresses you enter when you set up DHCP 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 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, enter them in the DNS Server fields in
the DHCP Setup screen.
AMG1302/AMG1202-TSeries User’s Guide
131
Chapter 8 Home Networking
• Some ISPs choose to disseminate the DNS server addresses using the DNS server extensions of
IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS
servers, chances are the DNS servers are conveyed through IPCP negotiation. The AMG1302/
AMG1202-TSeries supports the IPCP DNS server extensions through the DNS proxy feature.
Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It
does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If
your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the
DHCP Setup screen.
8.7.4 LAN TCP/IP
The AMG1302/AMG1202-TSeries has built-in DHCP server capability that assigns IP addresses and
DNS servers to systems that support DHCP client capability.
IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, so too do 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.
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 and you must enable the Network Address Translation (NAT) feature of the
AMG1302/AMG1202-TSeries. 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. Let's 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.
Once you have decided on the network number, pick an IP address that is easy to remember, for
instance, 192.168.1.1, for your AMG1302/AMG1202-TSeries, 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 AMG1302/AMG1202TSeries 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 AMG1302/AMG1202-TSeries 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, 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
• 172.16.0.0
132
— 10.255.255.255
— 172.31.255.255
AMG1302/AMG1202-TSeries User’s Guide
Chapter 8 Home Networking
• 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.
Note: 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”.
8.7.5 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction field controls the sending and receiving of RIP packets. When set to:
• Both - the AMG1302/AMG1202-TSeries will broadcast its routing table periodically and
incorporate the RIP information that it receives.
• In Only - the AMG1302/AMG1202-TSeries will not send any RIP packets but will accept all RIP
packets received.
• Out Only - the AMG1302/AMG1202-TSeries will send out RIP packets but will not accept any RIP
packets received.
• None - the AMG1302/AMG1202-TSeries will not send any RIP packets and will ignore any RIP
packets received.
The Version field controls the format and the broadcasting method of the RIP packets that the
AMG1302/AMG1202-TSeries sends (it recognizes both formats when receiving). RIP-1 is universally
supported; but RIP-2 carries more information. RIP-1 is probably adequate for most networks,
unless you have an unusual network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B
uses subnet broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load on
non-router machines since they generally do not listen to the RIP multicast address and so will not
receive the RIP packets. However, if one router uses multicasting, then all routers on your network
must use multicasting, also.
8.7.6 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.
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. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. IGMP version 3
supports source filtering, reporting or ignoring traffic from specific source address to a particular
host on the network. If you would like to read more detailed information about interoperability
between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP
address is used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The
address 224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address
AMG1302/AMG1202-TSeries User’s Guide
133
Chapter 8 Home Networking
224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts
(including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The
address 224.0.0.2 is assigned to the multicast routers group.
At start up, the AMG1302/AMG1202-TSeries queries all directly connected networks to gather
group membership. After that, the AMG1302/AMG1202-TSeries periodically updates this
information. IP multicasting can be enabled/disabled on the AMG1302/AMG1202-TSeries LAN and/
or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on
these interfaces.

Static Route
9.1 Overview
The AMG1302/AMG1202-TSeries usually uses the default gateway to route outbound traffic from
computers on the LAN to the Internet. To have the AMG1302/AMG1202-TSeries send data to
devices not reachable through the default gateway, use static routes.
For example, the next figure shows a computer (A) connected to the AMG1302/AMG1202-TSeries’s
LAN interface. The AMG1302/AMG1202-TSeries routes most traffic from A to the Internet through
the AMG1302/AMG1202-TSeries’s default gateway (R1). You create one static route to connect to
services offered by your ISP behind router R2. You create another static route to communicate with
a separate network behind a router R3 connected to the LAN.

Quality of Service (QoS)
10.1 Overview
Use the QoS screen to set up your AMG1302/AMG1202-TSeries to use QoS for traffic management.
Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and
the networking methods used to control bandwidth. QoS allows the AMG1302/AMG1202-TSeries to
group and prioritize application traffic and fine-tune network performance.
Without QoS, all traffic data are equally likely to be dropped when the network is congested. This
can cause a reduction in network performance and make the network inadequate for time-critical
applications such as video-on-demand.
The AMG1302/AMG1202-TSeries assigns each packet a priority and then queues the packet
accordingly. Packets assigned with a high priority are processed more quickly than those with low
priorities if there is congestion, allowing time-sensitive applications to flow more smoothly. Timesensitive applications include both those that require a low level of latency (delay) and a low level
of jitter (variations in delay) such as Voice over IP (VoIP) or Internet gaming, and those for which
jitter alone is a problem such as Internet radio or streaming video.
In the following figure, your Internet connection has an upstream transmission speed of 50 Mbps.
You configure a classifier to assign the highest priority queue (6) to VoIP traffic from the LAN
interface, so that voice traffic would not get delayed when there is network congestion. Traffic from
the boss’s IP address (192.168.1.23 for example) is mapped to queue 5. Traffic that does not
match these two classes are assigned priority queue based on the internal QoS mapping table on
the AMG1302/AMG1202-TSeries.

• Use the Queue screen (Section 10.3 on page 141) to configure QoS settings on the AMG1302/
AMG1202-TSeries.
• Use the Class Setup screen (Section 10.4 on page 143) to configure QoS settings on the
AMG1302/AMG1202-TSeries.
• Use the Game List screen (Section 10.5 on page 147) to give priority to traffic for specific
games.
10.1.2 What You Need to Know About QoS
802.1p
QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given
the same priority. 802.1p is a way of managing traffic in a network by grouping similar types of
traffic together and treating each type as a class. You can use 802.1p to give different priorities to
different packet types.
Tagging and Marking
In a QoS class, you can configure whether to add or change the DiffServ Code Point (DSCP) value
and IEEE 802.1p priority level in a matched packet. When the packet passes through a compatible
network, the networking device, such as a backbone switch, can provide specific treatment or
service based on the tag or marker.

10.6 QoS Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
10.6.1 IEEE 802.1p
IEEE 802.1p specifies the user priority field and defines up to eight separate traffic types. The
following table describes the traffic types defined in the IEEE 802.1d standard (which incorporates
the 802.1p).
Table 46 IEEE 802.1p Priority Level and Traffic Type
PRIORITY
LEVEL
TRAFFIC TYPE
Level 7
Typically used for network control traffic such as router configuration messages.
Level 6
Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in
delay).
Level 5
Typically used for video that consumes high bandwidth and is sensitive to jitter.
Level 4
Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network
Architecture) transactions.
Level 3
Typically used for “excellent effort” or better than best effort and would include important
business traffic that can tolerate some delay.
Level 2
This is for “spare bandwidth”.
Level 1
This is typically used for non-critical “background” traffic such as bulk transfers that are allowed
but that should not affect other applications and users.
Level 0
Typically used for best-effort traffic.
10.6.2 IP Precedence
Similar to IEEE 802.1p prioritization at layer-2, you can use IP precedence to prioritize packets in a
layer-3 network. IP precedence uses three bits of the eight-bit ToS (Type of Service) field in the IP
header. There are eight classes of services (ranging from zero to seven) in IP precedence. Zero is
the lowest priority level and seven is the highest.

10.6.3 Automatic Priority Queue Assignment
If you enable QoS on the AMG1302/AMG1202-TSeries, the AMG1302/AMG1202-TSeries can
automatically base on the IEEE 802.1p priority level, IP precedence and/or packet length to assign
priority to traffic which does not match a class.
The following table shows you the internal layer-2 and layer-3 QoS mapping on the AMG1302/
AMG1202-TSeries. On the AMG1302/AMG1202-TSeries, traffic assigned to higher priority queues
gets through faster while traffic in lower index queues is dropped if the network is congested.

Network Address Translation (NAT)
11.1 Overview
This chapter discusses how to configure NAT on the AMG1302/AMG1202-TSeries. 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 to a different IP
address known within another network.
11.1.1 What You Can Do in the NAT Screens
• Use the General screen (Section 11.2 on page 152) to activate/deactivate NAT for the default
WAN connection (PVC0).
• Use the Port Forwarding screen (Section 11.3 on page 153) to configure forward incoming
service requests to the server(s) on your local network.
• Use the DMZ screen to configure a default server (Section 11.4 on page 156).
11.1.2 What You Need To Know About NAT
Inside/Outside
Inside/outside denotes where a host is located relative to the AMG1302/AMG1202-TSeries, for
example, the computers of your subscribers are the inside hosts, while the web servers on the
Internet are the outside hosts.
Global/Local
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for
example, the local address refers to the IP address of a host when the packet is in the local
network, while the global address refers to the IP address of the host when the same packet is
traveling in the WAN side.
NAT
In the simplest form, NAT changes the source IP address in a packet received from a subscriber
(the inside local address) to another (the inside global address) before forwarding the packet to the
WAN side. When the response comes back, NAT translates the destination address (the inside
global address) back to the inside local address before forwarding it to the original inside host.
AMG1302/AMG1202-TSeries User’s Guide
151
Chapter 11 Network Address Translation (NAT)
Port Forwarding
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP,
that you can make visible to the outside world even though NAT makes your whole inside network
appear as a single computer to the outside world.
Finding Out More
See Section 11.5 on page 156 for advanced technical information on NAT.
11.2 The NAT General Screen
Use this screen to activate NAT for the default WAN connection (PVC0). Click Network Setting >
NAT to open the following screen.
Note: You must create an IP filter rule in addition to setting up NAT, to allow traffic from
the WAN to be forwarded through the AMG1302/AMG1202-TSeries.
Figure 67 Network Setting > NAT > General
The following table describes the labels in this screen.
Table 48 Network Setting > NAT > General
LABEL
DESCRIPTION
Active
Select this check box to enable NAT.
Max NAT/Firewall
Session Per User
When computers use peer to peer applications, such as file sharing applications, they
need to establish NAT sessions. If you do not limit the number of NAT sessions a single
client can establish, this can result in all of the available NAT sessions being used. In
this case, no additional NAT sessions can be established, and users may not be able to
access the Internet.
Each NAT session establishes a corresponding firewall session. Use this field to limit the
number of NAT/Firewall sessions client computers can establish through the AMG1302/
AMG1202-TSeries.
If your network has a small number of clients using peer to peer applications, you can
raise this number to ensure that their performance is not degraded by the number of
NAT sessions they can establish. If your network has a large number of users using peer
to peer applications, you can lower this number to ensure no single client is exhausting
all of the available NAT sessions.

11.3 The Port Forwarding Screen
Use this 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. You can allocate a server IP address that corresponds to a port or
a range of ports.
The most often used port numbers and services are shown in Appendix F on page 305. Please refer
to RFC 1700 for further information about port numbers.
Note: Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
Default Server IP Address
In addition to the servers for specified services, NAT supports a default server IP address. A default
server receives packets from ports that are not specified in this screen.
Note: If you do not assign a Default Server IP address, the AMG1302/AMG1202-TSeries
discards all packets received for ports that are not specified here or in the remote
management setup.
Configuring Servers Behind Port Forwarding (Example)
Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example),
port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a
third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address.
The NAT network appears as a single host on the Internet.

11.5 NAT Technical Reference
This chapter contains more information regarding NAT.
11.5.1 NAT Definitions
Inside/outside denotes where a host is located relative to the AMG1302/AMG1202-TSeries, for
example, the computers of your subscribers are the inside hosts, while the web servers on the
Internet are the outside hosts.
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for
example, the local address refers to the IP address of a host when the packet is in the local
network, while the global address refers to the IP address of the host when the same packet is
traveling in the WAN side.
Note that inside/outside refers to the location of a host, while global/local refers to the IP address
of a host used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in
156
AMG1302/AMG1202-TSeries User’s Guide
Chapter 11 Network Address Translation (NAT)
a packet when the packet is still in the local network, while an inside global address (IGA) is the IP
address of the same inside host when the packet is on the WAN side. The following table
summarizes this information.
Table 52 NAT Definitions
ITEM
DESCRIPTION
Inside
This refers to the host on the LAN.
Outside
This refers to the host on the WAN.
Local
This refers to the packet address (source or destination) as the packet travels on the LAN.
Global
This refers to the packet address (source or destination) as the packet travels on the WAN.
NAT never changes the IP address (either local or global) of an outside host.
11.5.2 What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber
(the inside local address) to another (the inside global address) before forwarding the packet to the
WAN side. When the response comes back, NAT translates the destination address (the inside
global address) back to the inside local address before forwarding it to the original inside host. Note
that the IP address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP.
In addition, you can designate servers, for example, a web server and a telnet server, on your local
network and make them accessible to the outside world. If you do not define any servers (for Manyto-One and Many-to-Many Overload mapping – see Table 53 on page 159), NAT offers the
additional benefit of firewall protection. With no servers defined, your AMG1302/AMG1202-TSeries
filters out all incoming inquiries, thus preventing intruders from probing your network. For more
information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
11.5.3 How NAT Works
Each packet has two addresses – a source address and a destination address. For outgoing packets,
the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global
Address) is the source address on the WAN. For incoming packets, the ILA is the destination
address on the LAN, and the IGA is the destination address on the WAN. 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 (and TCP or UDP source port numbers for Many-to-One and
Many-to-Many Overload NAT mapping) in each packet and then forwards it to the Internet. The
AMG1302/AMG1202-TSeries keeps track of the original addresses and port numbers so incoming
reply packets can have their original values restored. The following figure illustrates this.

11.5.5 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
158
AMG1302/AMG1202-TSeries User’s Guide
Chapter 11 Network Address Translation (NAT)
• One to One: In One-to-One mode, the AMG1302/AMG1202-TSeries maps one local IP address
to one global IP address.
• Many to One: In Many-to-One mode, the AMG1302/AMG1202-TSeries maps multiple local IP
addresses to one global IP address. This is equivalent to SUA (for instance, PAT, port address
translation), ZyXEL’s Single User Account feature that previous ZyXEL routers supported (the
SUA Only option in today’s routers).
• Many to Many Overload: In Many-to-Many Overload mode, the AMG1302/AMG1202-TSeries
maps the multiple local IP addresses to shared global IP addresses.
• Many-to-Many No Overload: In Many-to-Many No Overload mode, the AMG1302/AMG1202TSeries maps each local IP address to a unique global IP address.
• Server: This type allows you to specify inside servers of different services behind the NAT to be
accessible to the outside world.
Port numbers do NOT change for One-to-One and Many-to-Many No Overload NAT mapping
types.
The following table summarizes these types.

Port Binding
12.1 Overview
This chapter describes how to configure the port binding settings.
Port binding allows you to aggregate port connections into logical groups. You may bind WAN PVCs
to Ethernet ports and WLANs to specify how traffic is forwarded. Different ATM QoS settings can be
specified for each WAN PVC to meet bandwidth requirements for the type of traffic to be
transferred.
For example, three port binding groups could be created on the device (R1) for three different WAN
PVC connections. The first PVC (PVC0) is for non time-sensitive data traffic. The second and third
PVCs (PVC1 and PVC2) are for time sensitive Media-On-Demand (MOD) video traffic and VoIP
traffic, respectively.

Chapter 12 Port Binding
If a WAN PVC is bound to an ethernet port, traffic from the ethernet port will only be forwarded
through the specified WAN PVC and vice versa. If a port is not in a port binding group, traffic to and
from the port will be forwarded according to the routing table. See the tutorial section (Section on
page 37) for more details on configuring port binding for multiple WAN connections.
12.1.1 What You Can Do in the Port Binding Screens
• Use the General screen (Section 12.3 on page 162) to activate port binding.
• Use the Port Binding screen (Section 12.3 on page 162) to set up port binding groups.
• Use the Port Binding Summary screen (Section 12.3.1 on page 163) to view configured port
