CHAPTER 1
Introduction
1.1 Overview
This chapter introduces the main features and applications of the EMG3425-Q10A.
The EMG3425-Q10A extends the range of your existing wired network without additional wiring,
providing easy network access to mobile users. You can set up a wireless network with other IEEE
802.11a/ac/b/g/n compatible devices.
A range of services such as a firewall and content filtering are also available for secure Internet
computing. The EMG3425-Q10A also supports the new StreamBoost technology, which is smart
Quality of Service (QoS), to redistribute traffic over the EMG3425-Q10A for the best possible
performance in a home network.
There is one USB 2.0 port on the side panel of your EMG3425-Q10A, and the other one is on the
rear panel of your EMG3425-Q10A. You can connect USB (version 2.0 or lower) memory sticks, USB
hard drives, or USB devices for file sharing. The EMG3425-Q10A automatically detects the USB
devices.
Make sure the USB LED is off before removing your USB device. This will remove your USB device
safely, preventing file or data loss if it is being transmitted through the USB device.
Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB
storage devices (such as memory sticks, USB hard drives) and/or USB devices.
Other USB products are not guaranteed to function properly with the EMG3425-
Q10A.

1.1.1 Dual-Band
The EMG3425-Q10A is a dual-band AP and able to function both 2.4G and 5G networks at the same
time. You could use the 2.4 GHz band for regular Internet surfing and downloading while using the
5 GHz band for time sensitive traffic like high-definition video, music, and gaming.
Figure 1 Dual-Band Application
1.2 Applications
You can have the following networks with the EMG3425-Q10A:
•W ir e d. You can connect network devices via the Ethernet ports of the EMG3425-Q10A so that
they can communicate with each other and access the Internet.
•W ire less. Wireless clients can connect to the EMG3425-Q10A to access network resources. You
can use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-
compatible device.
•W AN . Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the EMG3425-Q10A
Use any of the following methods to manage the EMG3425-Q10A.
• WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web
Configurator to set up a wireless network with your EMG3425-Q10A.
• Web Configurator. This is recommended for everyday management of the EMG3425-Q10A using
a (supported) web browser.
Chapter 1 Introduction
EMG3425-Q10A User’s Guide

1.4 Good Habits for Managing the EMG3425-Q10A
Do the following things regularly to make the EMG3425-Q10A more secure and to manage the
EMG3425-Q10A 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 EMG3425-Q10A to its factory default settings. If
you backed up an earlier configuration file, you would not have to totally re-configure the
EMG3425-Q10A. You could simply restore your last configuration.
1.5 Resetting the EMG3425-Q10A
If you forget your password or IP address, or you cannot access the Web Configurator, you will need
to use the RESET button at the back of the EMG3425-Q10A to reload the factory-default
configuration file. This means that you will lose all configurations that you had previously saved, the
user name will be reset to “supervisor” or “admin”, the password will be reset to “supervisor” or
“1234”, and the IP address will be reset to “192.168.1.1” (router mode).
1.5.1 How to Use the RESET Button
1Make sure the power LED is on.
2Press the RESET button for one to four seconds to restart/reboot the EMG3425-Q10A.
3Press the RESET button for longer than five seconds to set the EMG3425-Q10A back to its factory-
default configurations.
1.6 The WPS Button
Your EMG3425-Q10A supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a
secure wireless network. WPS is an industry standard specification, defined by the Wi-Fi 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) on 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.
Chapter 1 Introduction
EMG3425-Q10A User’s Guide

You can use the WPS button ( ) on the front panel of the EMG3425-Q10A to activate WPS in
order to quickly set up a wireless network with strong security.
1Make sure the power LED is on (not blinking).
2Press the WPS button for more than three seconds and release it. Press the WPS button on another
WPS-enabled device within range of the EMG3425-Q10A.
Note: You must activate WPS on the EMG3425-Q10A and on another wireless device
within two minutes of each other.
For more information on using WPS, see Section 6.2 on page 38.
1.7 LEDs
Look at the LED lights on the front panel to determine the status of the EMG3425-Q10A. Use the
LED button on the rear panel of the device to turn the LED lights on or off. If you have already
pushed the LED button to the ON position but none of the LEDS are on, make sure the EMG3425-
Q10A is receiving power and the power is turned on.
Note: The Pow e r LED will be on even if you push the LED button to the OFF position.
This is for you to determine whether the EMG3425-Q10A is powered on.

When you enable this, the EMG3425-Q10A gets its IP address from the network’s
DHCP server (for example, your ISP). Users connected to the EMG3425-Q10A can
now access the network (i.e., the Internet if the IP address is given by the ISP).
The Web Configurator may no longer be accessible unless you know the IP address
assigned by the DHCP server to the EMG3425-Q10A. You need to reset the
EMG3425-Q10A to be able to access the Web Configurator again (see Section 25.7
on page 181 for details on how to reset the EMG3425-Q10A).
Also when you select this, you cannot enter an IP address for your EMG3425-Q10A
in the field below.

CHAPTER 6
Tutorials
6.1 Overview
This chapter provides tutorials for setting up your EMG3425-Q10A.
•Set Up a Wireless Network Using WPS
•Connect to EMG3425-Q10A Wireless Network without WPS
•Using Multiple SSIDs on the EMG3425-Q10A
6.2 Set Up a Wireless Network Using WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the EMG3425-Q10A as the AP and NWD210N as the wireless client which connects to a notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter
or PCI card).
There are two WPS methods for creating a secure connection via the web configurator or utility.
This tutorial shows you how to do both.
•Push But t on Configurat ion ( PBC) - create a secure wireless network simply by pressing a
button. See Section 6.2.1 on page 38. This is the easier method.
•PI N Configuration - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the EMG3425-Q10A’s interface. See Section 6.2.2 on page
39. This is the more secure method, since one device can authenticate the other.
6.2.1 Push Button Configuration (PBC)
1Make sure that your EMG3425-Q10A is turned on. Make sure the W I FI button (at the back panel of
the EMG3425-Q10A) is pushed in, and that the device is placed within range of your notebook.
2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (St a r t or
W PS button)
4Log into EMG3425-Q10A’s Web Configurator and press the Pu sh But t on in the Configuration >
N e tw ork > W ir ele ss LAN 2 .4 G > W PS St a t ion screen.

Note: Your EMG3425-Q10A has a WPS button located on its panel, as well as a WPS
button in its configuration utility. Both buttons have exactly the same function; you
can use one or the other.
Note: It doesn’t matter which button is pressed first. You must press the second button
within two minutes of pressing the first one.
The EMG3425-Q10A sends the proper configuration settings to the wireless client. This may take up
to two minutes. Then the wireless client is able to communicate with the EMG3425-Q10A securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both EMG3425-Q10A and wireless client (the NWD210N in this example).
Figure 17 Example WPS Process: PBC Method
6.2.2 PIN Configuration
When you use the PIN configuration method, you need to use both EMG3425-Q10A’s configuration
interface and the client’s utilities.
1Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method
to get a PIN number.

7Check the status of your wireless connection in the screen below.
8If the wireless client keeps trying to connect to or acquiring an IP address from the EMG3425-
Q10A, make sure you entered the correct security key.
If the connection has limited or no connectivity, make sure the DHCP server is enabled on the
EMG3425-Q10A.
If your connection is successful, open your Internet browser and enter http://www.zyxel.com or the
URL of any other web site in the address bar. If you are able to access the web site, your wireless
connection is successfully configured.
6.4 Using Multiple SSIDs on the EMG3425-Q10A
You can configure more than one SSID on a EMG3425-Q10A. See Section 9.4 on page 79.
This allows you to configure multiple independent wireless networks on the EMG3425-Q10A as if
there were multiple APs (virtual APs). Each virtual AP has its own SSID, wireless security type and
MAC filtering settings. That is, each SSID on the EMG3425-Q10A represents a different access
point/wireless network to wireless clients in the network.
Clients can associate only with the SSIDs for which they have the correct security settings. Clients
using different SSIDs can access the Internet and the wired network behind the EMG3425-Q10A
(such as a printer).

WAN
8.1 Overview
This chapter discusses the EMG3425-Q10A’s W AN screens. Use these screens to configure your
EMG3425-Q10A 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.
Figure 25 LAN and WAN
8.2 What You Can Do
•Use the I nt er n e t Connection screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (Section 8.4 on page 59).
8.3 What You Need To Know
The information in this section can help you configure the screens for your WAN connection, as well
as enable/disable some advanced features of your EMG3425-Q10A.
8.3.1 Configuring Your Internet Connection
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
Chapter 8 WAN
EMG3425-Q10A User’s Guide
58
over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username
and password (and service name) for user authentication.
WAN IP Address
The WAN IP address is an IP address for the EMG3425-Q10A, which makes it accessible from an
outside network. It is used by the EMG3425-Q10A to communicate with other devices in other
networks. It can be static (fixed) or dynamically assigned by the ISP each time the EMG3425-Q10A
tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP
encapsulation method).
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, you must know the IP address of a computer before you can access
it.
The EMG3425-Q10A can get the DNS server addresses in the following ways.
1The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2If your ISP dynamically assigns the DNS server IP addresses (along with the EMG3425-Q10A’s WAN
IP address), set the DNS server fields to get the DNS server address from the ISP.
WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by either using the
factory default or cloning the MAC address from a computer on your LAN. Choose Fa ctory Default
to select the factory assigned default MAC Address.
Otherwise, click Clone t he com pute r 's M AC addr e ss - I P Address and enter the IP address of
the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the
address will be copied to configuration file. It is recommended that you clone the MAC address prior
to hooking up the WAN Port.
Chapter 8 WAN
EMG3425-Q10A User’s Guide
59
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient)
or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of
hosts on the network - not everybody and not just 1.
Figure 26 Multicast Example
In the multicast example above, systems A and D comprise one multicast group. In multicasting,
the server only needs to send one data stream and this is delivered to systems A and D.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership
in a multicast group - it is not used to carry user data. The EMG3425-Q10A supports both IGMP
version 1 (I GMP- v 1 ) and IGMP version 2 (I GM P- v2 ).
At start up, the EMG3425-Q10A queries all directly connected networks to gather group
membership. After that, the EMG3425-Q10A periodically updates this information. IP multicasting
can be enabled/disabled on the EMG3425-Q10A WAN interface in the Web Configurator (W AN ).
Select N one to disable IP multicasting on these interfaces.

(DSL, cable, wireless, etc.) connection. The PPP over Et h e r net 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 EMG3425-Q10A (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the EEMG3425-Q10A does that
part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.
This screen displays when you select PPPoE encapsulation.

CHAPTER 9
Wireless LAN
9.1 Overview
This chapter discusses how to configure the wireless network settings in your EMG3425-Q10A. The
EMG3425-Q10A is able to function both 2.4GHz and 5GHz network at the same time. You can have
different wireless and wireless security settings for 2.4GHz and 5GHz wireless LANs. Click
Configura t ion > Ne t w ork > W ir e less LAN 2 .4 G or W ireless LAN 5 G to configure to do so.
See the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 30 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B are
called wireless clients. The wireless clients use the access point (AP) to interact with other devices
(such as the printer) or with the Internet. Your EMG3425-Q10A is the AP.
Chapter 9 Wireless LAN
EMG3425-Q10A User’s Guide

9.1.1 What You Can Do
•Use the Ge n e r a l screen to turn the wireless connection on or off, set up wireless security
between the EMG3425-Q10A and the wireless clients, and make other basic configuration
changes (Section 9.2 on page 73).
•Use the More AP screen to set up multiple wireless networks on your EMG3425-Q10A (Section
9.4 on page 79).
•Use the MAC Filte r screen to allow or deny wireless stations based on their MAC addresses from
connecting to the EMG3425-Q10A (Section 9.5 on page 81).
•Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section
9.6 on page 83).
•Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 9.7 on
page 83).
•Use the W PS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 9.8 on page 84).
•Use the W PS St at ion screen to add a wireless station using WPS (Section 9.9 on page 86).
•Use the Schedu ling screen to set the times your wireless LAN is turned on and off (Section 9.10
on page 86).
9.1.2 What You Should Know
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific channel, or
frequency, to send and receive information.
• Every wireless client in the same wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network. It can also protect the
information that is sent in the wireless network.
Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless
network.
SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the
SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change
the default SSID to something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for unauthorized devices to
get the SSID. In addition, unauthorized devices can still see the information that is sent in the
wireless network.
Chapter 9 Wireless LAN
EMG3425-Q10A User’s Guide
70
MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is
usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or
00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s
Guide or other documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to
use the wireless network. If a wireless client is allowed to use the wireless network, it still has to
have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the
wireless network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized
wireless client. Then, they can use that MAC address to use the wireless network.
User Authentication
You can make every user log in to the wireless network before they can use it. This is called user
authentication. However, every wireless client in the wireless network has to support IEEE 802.1x
to do this.
For wireless networks, there are two typical places to store the user names and passwords for each
user.
• In the AP: this feature is called a local user database or a local database.
• In a RADIUS server: this is a server used in businesses more than in homes.
If your AP does not provide a local user database and if you do not have a RADIUS server, you
cannot set up user names and passwords for your users.
Unauthorized 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.
Local user databases also have an additional limitation that is explained in the next section.
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.
1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds
of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 9 Wireless LAN
EMG3425-Q10A User’s Guide
71
The types of encryption you can choose depend on the type of user authentication. (See page 70
for information about this.)
For example, if the wireless network has a RADIUS server, you can choose W PA or W PA2 . If users
do not log in to the wireless network, you can choose no encryption, St at ic W EP, W PA- PSK, or
W PA2 - PSK.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. For example, suppose the AP does not have a local user database, and you do
not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network
has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA.
Therefore, you should set up St a t ic W EP in the wireless network.
Note: It is recommended that wireless networks use W PA- PSK, W PA, or stronger
encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is
still possible for unauthorized devices to figure out the original information pretty
quickly.
Note: It is not possible to use W PA- PSK, W PA or stronger encryption with a local user
database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select W PA2 or W PA2 - PSK in your EMG3425-Q10A, you can also select an option
(W PA/W PA- PSK Com pat ible) to support WPA/WPA-PSK as well. In this case, if some wireless
clients support WPA and some support WPA2, you should set up W PA2 - PSK or W PA2 (depending
on the type of wireless network login) and select the W PA/W PA- PSK Com pa t ible option in the
EMG3425-Q10A.
Many types of encryption use a key to protect the information in the wireless network. The longer
the key, the stronger the encryption. Every wireless client in the wireless network must have the
same key.
Guest WLAN
Guest WLAN allows you to set up a wireless network where users can access to Internet via the
EMG3425-Q10A (Z), but not other networks connected to the Z. In the following figure, a guest
user can access the Internet from the guest wireless network A via Z but not the home or company
network N.
Note: The home or company network N and Guest WLAN network are independent
networks.

A standard 20 MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps
(5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to
300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz channel offers
speeds of up to 1.3Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select Aut o 2 0 / 4 0
MHz or Aut o 2 0 / 4 0 / 8 0 MHz to allow the EMG3425-Q10A to adjust the channel

throughput. A 8 0 M H z channel consists of two adjacent 40 MHz channels. The wireless
clients must also support 4 0 M H z or 8 0 MHz. It is often better to use the 20 MHz setting
in a location where the environment hinders the wireless signal.
Select 2 0 M H z if you want to lessen radio interference with other wireless devices in your

Q10A. The key is not sent over the network.
Session Timeout The EMG3425-Q10A automatically disconnects a wireless client from the wireless and
wired networks after a period of inactivity. The wireless client needs to send the
username and password again before it can use the wireless and wired networks
again. Some wireless clients may prompt users for a username and password; other
clients may use saved login credentials. In either case, there is usually a short delay
while the wireless client logs in to the wireless network again.

LAN
10.1 Overview
This chapter describes how to configure LAN settings.
A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is a computer network limited to the immediate area, usually the same building or
floor of a building.
Figure 46 LAN Example
The LAN screens can help you configure a manage IP address, and partition your physical network
into logical networks.
10.2 What You Can Do
•Use the I P screen to change the IP address for your EMG3425-Q10A (Section 10.4 on page 90).
•Use the I P Alias screen to have the EMG3425-Q10A apply IP alias to create LAN subnets
(Section 10.5 on page 90).
•Use the I Pv6 LAN screen to configure the IPv6 address for your EMG3425-Q10A on the LAN
(Section 10.6 on page 91).
•Use the I GM P Snooping screen to enable IGMP Snooping and configure IGMP modes. (Section

10.3 What You Need To Know
The actual physical connection determines whether the EMG3425-Q10A 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 47 LAN and WAN IP Addresses
The LAN parameters of the EMG3425-Q10A are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS
server address(es), read the embedded Web Configurator help regarding what fields need to be
configured.
10.3.1 IP Pool Setup
The EMG3425-Q10A is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the EMG3425-Q10A itself) in
the lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for
mail, FTP, TFTP, web, etc., that you may have.
10.3.2 LAN TCP/IP
The EMG3425-Q10A has built-in DHCP server capability that assigns IP addresses and DNS servers
to systems that support DHCP client capability.
10.3.3 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The EMG3425-Q10A supports three logical LAN interfaces via its single physical
Ethernet interface with the EMG3425-Q10A itself as the gateway for each LAN network.

DHCP Server
11.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the EMG3425-Q10A’s LAN
as a DHCP server or disable it. When configured as a server, the EMG3425-Q10A provides the TCP/
IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on
your LAN, or else the computer must be manually configured.
11.1.1 What You Can Do
•Use the Ge n e r a l screen to enable the DHCP server (Section 11.2 on page 94).
•Use the Adva nced screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 11.3 on page 95).
•Use the Clie n t List screen to view the current DHCP client information (Section 11.4 on page
97).
11.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
MAC Addresses
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02. Find out the MAC addresses of your network devices if you intend to add them

CHAPTER 12
NAT
12.1 Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in
a packet. For example, the source address of an outgoing packet, used within one network is
changed to a different IP address known within another network.
The figure below is a simple illustration of a NAT network. 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 to the devices (A to D) connected to your EMG3425-Q10A. The
ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. All
traffic coming from A to D going out to the Internet use the IP address of the EMG3425-Q10A,
which is 192.168.1.1.
Figure 55 NAT Example
This chapter discusses how to configure NAT on the EMG3425-Q10A.
Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from
the WAN to be forwarded through the EMG3425-Q10A.
12.1.1 What You Can Do
•Use the Ge n e r a l screen to enable NAT (Section 12.2 on page 101).

forwarding settings to forward incoming service requests to the server(s) on your local network
(Section 12.3 on page 102).
•Use the Port Trigger screen to change your EMG3425-Q10A’s trigger port settings (Section
12.5.3 on page 107).
12.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Inside/Outside
This denotes where a host is located relative to the EMG3425-Q10A, for example, the computers of
your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Global/Local
This 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: Inside/outside refers to the location of a host, while global/local refers to the IP
address of a host used in a packet.
An inside local address (ILA) is the IP address of an inside host in 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.
Note: NAT never changes the IP address (either local or global) of an outside host.
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
Table 38 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.

network and make them accessible to the outside world. If you do not define any servers, NAT
offers the additional benefit of firewall protection. With no servers defined, your EMG3425-Q10A
filters out all incoming inquiries, thus preventing intruders from probing your network. For more
information on IP address translation, refer to RFC 1631, The I P Network Address Translator ( NAT).
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 in each packet and then forwards it to the Internet. The
EMG3425-Q10A keeps track of the original addresses and port numbers so incoming reply packets
can have their original values restored. The following figure illustrates this.

12.3 Port Forwarding Screen
Use this screen to forward incoming service requests to the server(s) on your local network and set
a default server. You may enter a single port number or a range of port numbers to be forwarded,
and the local IP address of the desired server. The port number identifies a service; for example,
web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or
where one server can support more than one service (for example both FTP and web service), it
might be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.
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.
Port forwarding allows you to define the local servers to which the incoming services will be
forwarded. To change your EMG3425-Q10A’s port forwarding settings, click Net w ork > N AT >
Port Forw arding. The screen appears as shown.
Note: If you do not assign a Defa ult Serve r, the EMG3425-Q10A discards all packets

12.5 Technical Reference
The following section contains additional technical information about the EMG3425-Q10A features
described in this chapter.
12.5.1 NATPort Forwarding: Services and Port Numbers
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP,
that you can make accessible to the outside world even though NAT makes your whole inside
network appear as a single machine to the outside world.
Use the Port Forw a rding screen to forward incoming service requests to the server(s) on your
local network. You may enter a single port number or a range of port numbers to be forwarded, and
the local IP address of the desired server. The port number identifies a service; for example, web
service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one
server can support more than one service (for example both FTP and web service), it might be
better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.
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.
12.5.2 NAT 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.
Figure 61 Multiple Servers Behind NAT Example
Chapter 12 NAT
EMG3425-Q10A User’s Guide
107
12.5.3 Trigger Port Forwarding
Some services use a dedicated range of ports on the client side and a dedicated range of ports on
the server side. With regular port forwarding you set a forwarding port in NAT to forward a service
(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN).
The problem is that port forwarding only forwards a service to a single LAN IP address. In order to
use the same service on a different LAN computer, you have to manually replace the LAN
computer's IP address in the forwarding port with another LAN computer's IP address.
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take
turns using the service. The EMG3425-Q10A records the IP address of a LAN computer that sends
traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port).
When the EMG3425-Q10A's WAN port receives a response with a specific port number and protocol
("incoming" port), the EMG3425-Q10A forwards the traffic to the LAN IP address of the computer
that sent the request. After that computer’s connection for that service closes, another computer on
the LAN can use the service in the same manner. This way you do not need to configure a new IP
address each time you want a different LAN computer to use the application.
12.5.4 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.
Figure 62 Trigger Port Forwarding Process: Example
1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a “trigger” port and causes the EMG3425-Q10A to record Jane’s computer IP address.
The EMG3425-Q10A associates Jane's computer IP address with the "incoming" port range of 6970-
7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The EMG3425-Q10A forwards the traffic to Jane’s computer IP address.
5Only Jane can connect to the Real Audio server until the connection is closed or times out. The
EMG3425-Q10A times out in three minutes with UDP (User Datagram Protocol), or two hours with
TCP/IP (Transfer Control Protocol/Internet Protocol).

Static Route
14.1 Overview
This chapter shows you how to configure static routes for your EMG3425-Q10A.
The EMG3425-Q10A usually uses the default gateway to route outbound traffic from computers on
the LAN to the Internet. To have the EMG3425-Q10A 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 EMG3425-Q10A’s LAN
interface. The EMG3425-Q10A routes most traffic from A to the Internet through the EMG3425-
Q10A’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.

CHAPTER 16
Firewall
16.1 Overview
Use these screens to enable and configure the firewall that protects your EMG3425-Q10A and your
LAN from unwanted or malicious traffic.
Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and
control access between the LAN and WAN. By default the firewall:
• allows traffic that originates from your LAN computers to go to all of the networks.
• blocks traffic that originates on the other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant
Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2).
However other traffic initiated from the WAN is blocked (3 and 4).

What is a Firewall?
Originally, the term “firewall” referred to a construction technique designed to prevent the spread of
fire from one room to another. The networking term "firewall" is a system or group of systems that
enforces an access-control policy between two networks. It may also be defined as a mechanism
used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot
solve every security problem. A firewall is one of the mechanisms used to establish a network
security perimeter in support of a network security policy. It should never be the only mechanism or
method employed. For a firewall to guard effectively, you must design and deploy it appropriately.
This requires integrating the firewall into a broad information-security policy. In addition, specific
policies must be implemented within the firewall itself.
Stateful Inspection Firewall
Stateful inspection firewalls restrict access by screening data packets against defined access rules.
They make access control decisions based on IP address and protocol. They also "inspect" the
session data to assure the integrity of the connection and to adapt to dynamic protocols. These
firewalls generally provide the best speed and transparency; however, they may lack the granular
application level access control or caching that some proxies support. Firewalls, of one type or
another, have become an integral part of standard security solutions for enterprises.
About the EMG3425-Q10A Firewall
The EMG3425-Q10A’s firewall feature physically separates the LAN and the WAN and acts as a
secure gateway for all data passing between the networks.
It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when
activated (click the General tab under Fir e w all and then click the Enable Fir e w a ll check box).
The EMG3425-Q10A's purpose is to allow a private Local Area Network (LAN) to be securely
connected to the Internet. The EMG3425-Q10A can be used to prevent theft, destruction and
modification of data, as well as log events, which may be important to the security of your network.
The EMG3425-Q10A is installed between the LAN and a broadband modem connecting to the
Internet. This allows it to act as a secure gateway for all data passing between the Internet and the
LAN.
The EMG3425-Q10A has one Ethernet WAN port and four Ethernet LAN ports, which are used to
physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the
broadband (cable or DSL) modem to the Internet.
The LAN (Local Area Network) port attaches to a network of computers, which needs security from
the outside world. These computers will have access to Internet services such as e-mail, FTP and
the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host
is authorized to use a specific service.
Guidelines For Enhancing Security With Your Firewall
1Change the default password via Web Configurator.
2Think about access control before you connect to the network in any way, including attaching a
modem to the port.
Chapter 16 Firewall
EMG3425-Q10A User’s Guide

3Limit who can access your router.
4Don't enable any local service (such as NTP) that you don't use. Any enabled service could present
a potential security risk. A determined hacker might be able to find creative ways to misuse the
enabled services to access the firewall or the network.
5For local services that are enabled, protect against misuse. Protect by configuring the services to
communicate only with specific peers, and protect by configuring rules to block packets for the
services at specific interfaces.
6Protect against IP spoofing by making sure the firewall is active.
7Keep the firewall in a secured (locked) room.

Parental Control
19.1 Overview
Parental controls allow you to block specific URLs. You can also define time periods and days during
which the EMG3425-Q10A performs parental control on a specific user.
19.1.1 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Keyword Blocking URL Checking
The EMG3425-Q10A checks the URL’s domain name (or IP address) and file path separately when
performing keyword blocking.
The URL’s domain name or IP address is the characters that come before the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is
www.zyxel.com.tw.
The file path is the characters that come after the first slash in the URL. For example, with the URL
www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.
Since the EMG3425-Q10A checks the URL’s domain name (or IP address) and file path separately, it
will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/
pressroom.php, the EMG3425-Q10A would find “tw” in the domain name (www.zyxel.com.tw). It
would also find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.

Domain Name or IP Address URL Checking
By default, the EMG3425-Q10A checks the URL’s domain name or IP address when performing
keyword blocking.
This means that the EMG3425-Q10A checks the characters that come before the first slash in the
URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, content filtering only searches
for keywords within www.zyxel.com.tw.
Full Path URL Checking
Full path URL checking has the EMG3425-Q10A check the characters that come before the last
slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking
searches for keywords within www.zyxel.com.tw/news/.

CHAPTER 20
Bandwidth Management
20.1 Overview
Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and
the networking methods used to control the use of bandwidth. Without QoS, all traffic data is
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 application such as video-on-
demand.
Configure QoS on the EMG3425-Q10A to group and prioritize application traffic and fine-tune
network performance. Setting up QoS involves these steps:
1Configure classifiers to sort traffic into different flows.
2Assign priority and define actions to be performed for a classified traffic flow.
The EMG3425-Q10A assigns each packet a priority and then queues the packet accordingly. Packets
assigned a high priority are processed more quickly than those with low priority if there is
congestion, allowing time-sensitive applications to flow more smoothly. Time-sensitive 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.
This chapter contains information about configuring QoS and editing classifiers.
20.1.1 What You Can Do in this Chapter
•The Ge nera l screen lets you enable or disable QoS and set the upstream bandwidth (Section
20.3 on page 135).
•The Queue Se t up screen lets you configure QoS queue assignment (Section 20.4 on page 136).

The following terms and concepts may help as you read through this chapter.
QoS versus CoS
QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given
the same priority. CoS (class of service) is a way of managing traffic in a network by grouping
Chapter 20 Bandwidth Management
EMG3425-Q10A User’s Guide
134
similar types of traffic together and treating each type as a class. You can use CoS to give different
priorities to different packet types.
CoS technologies include IEEE 802.1p layer 2 tagging and DiffServ (Differentiated Services or DS).
IEEE 802.1p tagging makes use of three bits in the packet header, while DiffServ is a new protocol
and defines a new DS field, which replaces the eight-bit ToS (Type of Service) field in the IP header.
Tagging and Marking
In a QoS class, you can configure whether to add or change the DSCP (DiffServ Code Point) value,
IEEE 802.1p priority level and VLAN ID number 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.
Traffic Shaping
Bursty traffic may cause network congestion. Traffic shaping regulates packets to be transmitted
with a pre-configured data transmission rate using buffers (or queues). Your EMG3425-Q10A uses
the Token Bucket algorithm to allow a certain amount of large bursts while keeping a limit at the
average rate.
Traffic Policing
Traffic policing is the limiting of the input or output transmission rate of a class of traffic on the
basis of user-defined criteria. Traffic policing methods measure traffic flows against user-defined
criteria and identify it as either conforming, exceeding or violating the criteria.
The EMG3425-Q10A supports three incoming traffic metering algorithms: Token Bucket Filter
(TBF), Single Rate Two Color Maker (srTCM), and Two Rate Two Color Marker (trTCM). You can

Upstream
Bandwidth
Enter the amount of upstream bandwidth for the WAN interfaces that you want to allocate
using QoS.
The recommendation is to set this speed to match the interfaces’ actual transmission speed.
For example, set the WAN interfaces’ speed to 100000 kbps if your Internet connection has
an upstream transmission speed of 100 Mbps.
You can set this number higher than the interfaces’ actual transmission speed. The
EMG3425-Q10A uses up to 95% of the DSL port’s actual upstream transmission speed even
if you set this number higher than the DSL port’s actual transmission speed.
You can also set this number lower than the interfaces’ actual transmission speed. This will
cause the EMG3425-Q10A to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the EMG3425-Q10A automatically sets this number to be 95%
of the WAN interfaces’ actual upstream transmission speed.

use a 100 Mbps wired Ethernet WAN connection.
You can also set this number lower than the WAN interfaces’ actual transmission speed. This
will cause the EMG3425-Q10A to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the EMG3425-Q10A automatically sets this to the LAN

20.5 The Class Setup Screen
Use this screen to add, edit or delete QoS classifiers. A classifier groups traffic into data flows
according to specific criteria such as the source address, destination address, source port number,
destination port number or incoming interface. For example, you can configure a classifier to select
traffic from the same protocol port (such as Telnet) to form a flow.
You can give different priorities to traffic that the EMG3425-Q10A forwards out through the WAN
interface. Give high priority to voice and video to make them run more smoothly. Similarly, give low
priority to many large file downloads so that they do not reduce the quality of other applications.

20.6 Technical Reference
The following section contains additional technical information about the EMG3425-Q10A features
described in this chapter.
IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN
membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user
priority. The VLAN ID associates a frame with a specific VLAN and provides the information that
devices need to process the frame across the network.
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).
VLAN ID If you select Rem ark , enter a VLAN ID number with which the EMG3425-Q10A replaces the
VLAN ID of the frames.
If you select Rem ove, the EMG3425-Q10A deletes the VLAN ID of the frames before
forwarding them out.
If you select Add, the EMG3425-Q10A treat all matched traffic untagged and add a second
VLAN ID.
If you select Uncha nge, the EMG3425-Q10A keep the VLAN ID in the packets.

DiffServ
QoS is used to prioritize source-to-destination traffic flows. All packets in the flow are given the
same priority. You can use CoS (class of service) to give different priorities to different packet
types.
DiffServ (Differentiated Services) is a class of service (CoS) model that marks packets so that they
receive specific per-hop treatment at DiffServ-compliant network devices along the route based on
the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs)
indicating the level of service desired. This allows the intermediary DiffServ-compliant network
devices to handle the packets differently depending on the code points without the need to
negotiate paths or remember state information for every flow. In addition, applications do not have
to request a particular service or give advanced notice of where the traffic is going.
DSCP and Per-Hop Behavior
DiffServ defines a new Differentiated Services (DS) field to replace the Type of Service (TOS) field
in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define
up to 64 service levels. The following figure illustrates the DS field.
DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ
compliant, ToS-enabled network device will not conflict with the DSCP mapping.
The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet
gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be
marked for different kinds of forwarding. Resources can then be allocated according to the DSCP
values and the configured policies.
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.
Automatic Priority Queue Assignment
If you enable QoS on the EMG3425-Q10A, the EMG3425-Q10A 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.
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.
DSCP (6 bits) Unused (2 bits)

The following table shows you the internal layer-2 and layer-3 QoS mapping on the EMG3425-
Q10A. On the EMG3425-Q10A, traffic assigned to higher priority queues gets through faster while
traffic in lower index queues is dropped if the network is congested.
Token Bucket
The token bucket algorithm uses tokens in a bucket to control when traffic can be transmitted. The
bucket stores tokens, each of which represents one byte. The algorithm allows bursts of up to b
bytes which is also the bucket size, so the bucket can hold up to b tokens. Tokens are generated
and added into the bucket at a constant rate. The following shows how tokens work with packets:
• A packet can be transmitted if the number of tokens in the bucket is equal to or greater than the
size of the packet (in bytes).
• After a packet is transmitted, a number of tokens corresponding to the packet size is removed
from the bucket.

• If there are no tokens in the bucket, the EMG3425-Q10A stops transmitting until enough tokens
are generated.
• If not enough tokens are available, the EMG3425-Q10A treats the packet in either one of the
following ways:
In traffic shaping:
• Holds it in the queue until enough tokens are available in the bucket.
In traffic policing:
•Drops it.
• Transmits it but adds a DSCP mark. The EMG3425-Q10A may drop these marked packets if the
network is overloaded.
Configure the bucket size to be equal to or less than the amount of the bandwidth that the interface
can support. It does not help if you set it to a bucket size over the interface’s capability. The smaller
the bucket size, the lower the data transmission rate and that may cause outgoing packets to be
dropped. A larger transmission rate requires a big bucket size. For example, use a bucket size of 10
kbytes to get the transmission rate up to 10 Mbps.
Single Rate Three Color Marker
The Single Rate Three Color Marker (srTCM, defined in RFC 2697) is a type of traffic policing that
identifies packets by comparing them to one user-defined rate, the Committed Information Rate
(CIR), and two burst sizes: the Committed Burst Size (CBS) and Excess Burst Size (EBS).
The srTCM evaluates incoming packets and marks them with one of three colors which refer to
packet loss priority levels. High packet loss priority level is referred to as red, medium is referred to
as yellow and low is referred to as green.
The srTCM is based on the token bucket filter and has two token buckets (CBS and EBS). Tokens
are generated and added into the bucket at a constant rate, called Committed Information Rate
(CIR). When the first bucket (CBS) is full, new tokens overflow into the second bucket (EBS).
All packets are evaluated against the CBS. If a packet does not exceed the CBS it is marked green.
Otherwise it is evaluated against the EBS. If it is below the EBS then it is marked yellow. If it
exceeds the EBS then it is marked red.
The following shows how tokens work with incoming packets in srTCM:
• A packet arrives. The packet is marked green and can be transmitted if the number of tokens in
the CBS bucket is equal to or greater than the size of the packet (in bytes).
• After a packet is transmitted, a number of tokens corresponding to the packet size is removed
from the CBS bucket.
• If there are not enough tokens in the CBS bucket, the EMG3425-Q10A checks the EBS bucket.
The packet is marked yellow if there are sufficient tokens in the EBS bucket. Otherwise, the
packet is marked red. No tokens are removed if the packet is dropped.
Two Rate Three Color Marker
The Two Rate Three Color Marker (trTCM, defined in RFC 2698) is a type of traffic policing that
identifies packets by comparing them to two user-defined rates: the Committed Information Rate
(CIR) and the Peak Information Rate (PIR). The CIR specifies the average rate at which packets are
admitted to the network. The PIR is greater than or equal to the CIR. CIR and PIR values are based
Chapter 20 Bandwidth Management
EMG3425-Q10A User’s Guide
146
on the guaranteed and maximum bandwidth respectively as negotiated between a service provider
and client.
The trTCM evaluates incoming packets and marks them with one of three colors which refer to
packet loss priority levels. High packet loss priority level is referred to as red, medium is referred to
as yellow and low is referred to as green.
The trTCM is based on the token bucket filter and has two token buckets (Committed Burst Size
(CBS) and Peak Burst Size (PBS)). Tokens are generated and added into the two buckets at the CIR
and PIR respectively.
All packets are evaluated against the PIR. If a packet exceeds the PIR it is marked red. Otherwise it
is evaluated against the CIR. If it exceeds the CIR then it is marked yellow. Finally, if it is below the
CIR then it is marked green.
The following shows how tokens work with incoming packets in trTCM:
• A packet arrives. If the number of tokens in the PBS bucket is less than the size of the packet (in
bytes), the packet is marked red and may be dropped regardless of the CBS bucket. No tokens
are removed if the packet is dropped.
• If the PBS bucket has enough tokens, the EMG3425-Q10A checks the CBS bucket. The packet is
marked green and can be transmitted if the number of tokens in the CBS bucket is equal to or
greater than the size of the packet (in bytes). Otherwise, the packet is marked yellow.

CHAPTER 21
Remote Management
21.1 Overview
This chapter provides information on the Remote Management screens.
Remote Management allows you to manage your EMG3425-Q10A from a remote location through
the following interfaces:
•LAN and WAN
•LAN only
•WAN only
Note: The EMG3425-Q10A is managed using the Web Configurator.
21.2 What You Can Do in this Chapter
•Use the WWW screen to define the interface/s from which the EMG3425-Q10A can be managed
remotely using the web and specify a secure client that can manage the EMG3425-Q10A (Section
21.4 on page 148).
•Use the Te lnet screen to define the interface/s from which the EMG3425-Q10A can be managed
remotely using Telnet service and specify a secure client that can manage the EMG3425-Q10A
(Section 21.5 on page 151).
• Your EMG3425-Q10A can act as an SNMP agent, which allows a manager station to manage and
monitor the EMG3425-Q10A through the network. Use the SN M P screen to configure SNMP
settings. You can also specify from which IP addresses the access can come (Section 21.6 on
page 152).
•Use the W a k e On LAN screen to enable Wake on LAN and remotely turn on a device on the local
network (Section 21.7 on page 154).
•Use the TR0 6 9 screen to configure the EMG3425-Q10A’s TR-069 auto-configuration settings and
import CA certificates to the EMG3425-Q10A (Section 21.8 on page 155).
21.3 What You Need to Know
Remote management over LAN or WAN will not work when:
1The IP address in the Secured Clie n t I P Addre ss field (Section 21.4 on page 148) does not match
the client IP address. If it does not match, the EMG3425-Q10A will disconnect the session
immediately.
Chapter 21 Remote Management
EMG3425-Q10A User’s Guide

21.6 SNMP Screen
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your EMG3425-Q10A supports SNMP agent functionality, which allows a
manager station to manage and monitor the EMG3425-Q10A through the network. The EMG3425-
Q10A supports SNMP version one (SNMPv1) and version two (SNMPv2c). The next figure illustrates
an SNMP management operation.
Figure 85 SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the EMG3425-
Q10A). An agent translates the local management information from the managed device into a
form compatible with SNMP. The manager is the console through which network administrators
perform network management functions. It executes applications that control and monitor
managed devices.

The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of
packets received, node port status etc. A Management Information Base (MIB) is a collection of
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an
agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it
initiates a Get operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.

CHAPTER 22
Universal Plug-and-Play (UPnP)
22.1 Overview
This chapter introduces the UPnP feature in the web configurator.
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
22.2 What You Need to Know
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP
compatible device installed on your network will appear as a separate icon. Selecting the icon of a
UPnP device will allow you to access the information and properties of that device.
22.2.1 NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP
network devices can automatically configure network addressing, announce their presence in the
network to other UPnP devices and enable exchange of simple product and service descriptions.
NAT traversal allows the following:
• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the NAT chapter for more information on NAT.
22.2.2 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configuration may also
be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the EMG3425-Q10A allows multicast messages on the LAN only.
Chapter 22 Universal Plug-and-Play (UPnP)

USB Media Sharing
23.1 Overview
This chapter describes how to configure the media sharing settings on the EMG3425-Q10A.
Note: The read and write performance may be affected by amount of file-sharing traffic
on your network, type of connected USB device and your USB version (1.1 or 2.0).
Media Server
You can set up your EMG3425-Q10A to act as a media server to provide media (like video) to DLNA-
compliant players, such as Windows Media Player, ZyXEL DMAs (Digital Media Adapters), Xboxes or
PS3s. The media server and clients must have IP addresses in the same subnet.
The EMG3425-Q10A media server enables you to:
• Publish all folders for everyone to play media files in the USB storage device connected to the
EMG3425-Q10A.
• Use hardware-based media clients like the DMA-2500 to play the files.
Note: Anyone on your network can play the media files in the published folders. No user
name and password nor other form of security is required.

Workgroup name
This is the name given to a set of computers that are connected on a network and share resources
such as a printer or files. Windows automatically assigns the workgroup name when you set up a
network.
File Systems
A file system is a way of storing and organizing files on your hard drive and storage device. Often
different operating systems such as Windows or Linux have different file systems. The file-sharing
feature on your EMG3425-Q10A supports New Technology File System (NTFS), File Allocation Table
(FAT) and FAT32 file systems.
Windows/CIFS
Common Internet File System (CIFS) is a standard protocol supported by most operating systems
in order to share files across the network.
CIFS runs over TCP/IP but uses the SMB (Server Message Block) protocol found in Microsoft
Windows for file and printer access; therefore, CIFS will allow all applications, not just Web
browsers, to open and share files across the Internet.
The EMG3425-Q10A uses Common Internet File System (CIFS) protocol for its file sharing
functions. CIFS compatible computers can access the USB file storage devices connected to the
EMG3425-Q10A. CIFS protocol is supported on Microsoft Windows, Linux Samba and other
operating systems (refer to your systems specifications for CIFS compatibility).
Samba
SMB is a client-server protocol used by Microsoft Windows systems for sharing files, printers, and
so on.
Samba is a free SMB server that runs on most Unix and Unix-like systems. It provides an
implementation of an SMB client and server for use with non-Microsoft operating systems.
File Transfer Protocol
This is a method of transferring data from one computer to another over a network such as the
Internet.

If a keyword that is listed in the Ke yw ord List is not blocked when it is found in a URL, customize
the keyword blocking using commands. See the Customizing Keyword Blocking URL Checking
section in the IPv6 Firewall chapter.
I cannot access the Web Configurator after I switched to AP mode.
When you change from router mode to AP mode, your computer must have an IP address in the
range between “192.168.1.3” and “192.168.1.254”.
Refer to Appendix B on page 203 for instructions on how to change your computer’s IP address.
What factors may cause intermittent or unstabled wireless connection? How can I solve this
problem?
The following factors may cause interference:
• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless
devices.
To optimize the speed and quality of your wireless connection, you can:
• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless networks or surrounding
wireless electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the wireless client.
• Reduce the number of wireless clients connecting to the same AP simultaneously, or add
additional APs if necessary.

• Try closing some programs that use the Internet, especially peer-to-peer applications. If the
wireless client is sending or receiving a lot of information, it may have too many programs open
that use the Internet.
• Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas
upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the
antennas in different directions and check which provides the strongest signal to the wireless
clients.
