Introduction
1.1 Overview
This chapter introduces the main features and applications of the EMG2926-Q10A.
The EMG2926-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 EMG2926-Q10A also supports the new StreamBoost technology, which is smart
Quality of Service (QoS), to redistribute traffic over the EMG2926-Q10A for the best possible
performance in a home network.
There are two USB 2.0 ports on the side panel of your EMG2926-Q10A. You can connect USB
(version 2.0 or lower) memory sticks, USB hard drives, or USB devices for file sharing. The
EMG2926-Q10A automatically detects the USB devices.
Two USB eject buttons are located above the USB ports. Push the eject button of the corresponding
USB port for 2 seconds. 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
(such as USB printers). Other USB products are not guaranteed to function
properly with the EMG2926-Q10A.

Chapter 1 Introduction
1.1.1 Dual-Band
The EMG2926-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 2 Dual-Band Application
1.2 Applications
Your can have the following networks using the EMG2926-Q10A:
• Wired. You can connect network devices via the Ethernet ports of the EMG2926-Q10A so that
they can communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the EMG2926-Q10A to access network resources. You
can use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPScompatible device.
• WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the EMG2926-Q10A
Use any of the following methods to manage the EMG2926-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 ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the EMG2926-Q10A using
a (supported) web browser.

Chapter 1 Introduction
1.4 Good Habits for Managing the EMG2926-Q10A
Do the following things regularly to make the EMG2926-Q10A more secure and to manage the
EMG2926-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 EMG2926-Q10A to its factory default settings. If
you backed up an earlier configuration file, you would not have to totally re-configure the
EMG2926-Q10A. You could simply restore your last configuration.
1.5 Resetting the EMG2926-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 EMG2926-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 “admin” and the IP address will be reset to “192.168.0.1”.
1.5.1 How to Use the RESET Button
Make sure the power LED is on.
Press the RESET button for one to four seconds to restart/reboot the EMG2926-Q10A.
Press the RESET button for longer than five seconds to set the EMG2926-Q10A back to its factorydefault configurations.
1.6 The WPS Button
Your EMG2926-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) 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.
You can use the WPS button (
) on the front panel of the EMG2926-Q10A to activate WPS in
order to quickly set up a wireless network with strong security.

Chapter 1 Introduction
Make sure the power LED is on (not blinking).
Press the WPS button for more than three seconds and release it. Press the WPS button on another
WPS-enabled device within range of the EMG2926-Q10A.
Note: You must activate WPS in the EMG2926-Q10A and in another wireless device within
two minutes of each other.
For more information on using WPS, see Section 8.2 on page 57.
1.7 LEDs
Look at the LED lights on the front panel to determine the status of the EMG2926-Q10A. Use the
LED button at the side 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 EMG2926Q10A is receiving power and the power is turned on.
Note: The Power LED will be on even if you push the LED button to the OFF position.
This is for you to determine whether the EMG2926-Q10A is powered on.

2.3.2 Connection Type: PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with
a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data
networks.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for instance, RADIUS).
One of the benefits of PPPoE is the ability to let end users access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily create
and offer new IP services for specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber's site.
By implementing PPPoE directly on the EMG2926-Q10A (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the EMG2926-Q10A does that
part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

8.1 Overview
This chapter provides tutorials for setting up your EMG2926-Q10A.
• Set Up a Wireless Network with WPS
• Configure Wireless Security without WPS
• Using Multiple SSIDs on the EMG2926-Q10A
8.2 Set Up a Wireless Network with WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the EMG2926-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. This tutorial shows you how to do
both.
• Push Button Configuration (PBC) - create a secure wireless network simply by pressing a
button. See Section 8.2.1 on page 57.This is the easier method.
• PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the EMG2926-Q10A’s interface. See Section 8.2.2 on page
58. This is the more secure method, since one device can authenticate the other.
8.2.1 Push Button Configuration (PBC)
Make sure that your EMG2926-Q10A is turned on. Make sure the WIFI button (at the side panel of
the EMG2926-Q10A) is pushed in, and that the device is placed within range of your notebook.
Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or
WPS button)
Log into EMG2926-Q10A’s Web Configurator and press the Push Button in the Configuration >
Network > Wireless LAN 2.4G > WPS Station screen.

Note: Your EMG2926-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 EMG2926-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 EMG2926-Q10A securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both EMG2926-Q10A and wireless client (the NWD210N in this example).

8.4 Using Multiple SSIDs on the EMG2926-Q10A
You can configure more than one SSID on a EMG2926-Q10A. See Section 11.4 on page 99.
This allows you to configure multiple independent wireless networks on the EMG2926-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 EMG2926-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 EMG2926-Q10A
(such as a printer).

WAN
10.1 Overview
This chapter discusses the EMG2926-Q10A’s WAN screens. Use these screens to configure your
EMG2926-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 48 LAN and WAN
10.2 What You Can Do
• Use the Internet Connection screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (Section 10.4 on page 78).
• Use the Advanced screen to enable multicasting, configure Windows networking and bridge
(Section 10.5 on page 84).
10.3 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 EMG2926-Q10A.
EMG2926-Q10A User’s Guide

Chapter 10 WAN
10.3.1 Configuring Your Internet Connection
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username
and password (and service name) for user authentication.
WAN IP Address
The WAN IP address is an IP address for the EMG2926-Q10A, which makes it accessible from an
outside network. It is used by the EMG2926-Q10A to communicate with other devices in other
networks. It can be static (fixed) or dynamically assigned by the ISP each time the EMG2926-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 EMG2926-Q10A can get the DNS server addresses in the following ways.
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, manually enter them in the DNS server fields.
If your ISP dynamically assigns the DNS server IP addresses (along with the EMG2926-Q10A’s WAN
IP address), set the DNS server fields to get the DNS server address from the ISP.
IPv6 Rapid Deployment
Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4
network. When the EMG2926-Q10A has an IPv4 WAN address and you set IPv6/IPv4 mode to
IPv4 Only, you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4
network.
The EMG2926-Q10A generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6
traffic to the ISP’s Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The
local network can also use IPv4 services. The EMG2926-Q10A uses it’s configured IPv4 WAN IP to
route IPv4 traffic to the IPv4 Internet.

WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by either using the
factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default
to select the factory assigned default MAC Address.
Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of
the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the
address will be copied to configuration file. It is recommended that you clone the MAC address prior
to hooking up the WAN Port.
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 50 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.
EMG2926-Q10A User’s Guide
77
Chapter 10 WAN
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 EMG2926-Q10A supports both IGMP
version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the EMG2926-Q10A queries all directly connected networks to gather group
membership. After that, the EMG2926-Q10A periodically updates this information. IP multicasting
can be enabled/disabled on the EMG2926-Q10A WAN interface in the Web Configurator (WAN).
Select None to disable IP multicasting on these interfaces.

10.4.2 PPPoE Encapsulation
The EMG2926-Q10A supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem
(DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection
using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example Radius).
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a
function known as dynamic service selection. This enables the service provider to easily create and
offer new IP services for individuals.
EMG2926-Q10A User’s Guide
81
Chapter 10 WAN
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 EMG2926-Q10A (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the EMG2926-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.

Wireless LAN
11.1 Overview
This chapter discusses how to configure the wireless network settings in your EMG2926-Q10A. The
EMG2926-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
Configuration > Network > Wireless LAN 2.4G or Wireless LAN 5G 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 54 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 EMG2926-Q10A is the AP.
EMG2926-Q10A User’s Guide
86
Chapter 11 Wireless LAN
11.1.1 What You Can Do
• Use the General screen to turn the wireless connection on or off, set up wireless security
between the EMG2926-Q10A and the wireless clients, and make other basic configuration
changes (Section 11.2 on page 91).
• Use the More AP screen to set up multiple wireless networks on your EMG2926-Q10A (Section
11.4 on page 99).
• Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the EMG2926-Q10A (Section 11.5 on page 102).
• Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section
11.6 on page 104).
• Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 11.7 on
page 105).
• Use the WPS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 11.8 on page 105).
• Use the WPS Station screen to add a wireless station using WPS (Section 11.9 on page 107).
• Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section
11.10 on page 107).
11.1.2 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.
EMG2926-Q10A User’s Guide
87
Chapter 11 Wireless LAN
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.
EMG2926-Q10A User’s Guide
88
Chapter 11 Wireless LAN
The types of encryption you can choose depend on the type of user authentication. (See page 88
for information about this.)
Table 30 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 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 Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, 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 WPA-PSK, WPA 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 WPA2 or WPA2-PSK in your EMG2926-Q10A, you can also select an option
(WPA/WPA-PSK Compatible) to support WPA/WPA-PSK as well. In this case, if some wireless
clients 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/WPA-PSK Compatible option in the
EMG2926-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
EMG2926-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.
Note: Only Router mode supports guest WLAN.

WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a wireless network with strong security, without having to configure
security settings manually. Depending on the devices in your network, you can either press a
button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification

Number) in the devices. Then, they connect and set up a secure network by themselves. See how
to set up a secure wireless network using WPS in the Section 8.2 on page 57.

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 Auto 20/40
MHz or Auto 20/40/80 MHz to allow the EMG2926-Q10A to adjust the channel
bandwidth automatically.
40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless
clients must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting
in a location where the environment hinders the wireless signal.
Select 20 MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.

Timer
The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/
WPA2-PSK key management) or RADIUS server (if using WPA/WPA2 key
management) sends a new group key out to all clients. The re-keying process is the
WPA/WPA2 equivalent of automatically changing the WEP key for an AP and all
stations in a WLAN on a periodic basis. Setting of the Group Key Update Timer is
also supported in WPA-PSK/WPA2-PSK mode.

Session Timeout
The EMG2926-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
12.1 Overview
This chapter describes how to configure LAN settings.
A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is a computer network limited to the immediate area, usually the same building or
floor of a building.
Figure 71 LAN Example
The LAN screens can help you configure a manage IP address, and partition your physical network
into logical networks.
12.2 What You Can Do
• Use the IP screen to change the IPv4 address for your EMG2926-Q10A (Section 12.4 on page
110).
• Use the IP Alias screen to have the EMG2926-Q10A apply IP alias to create LAN subnets
(Section 12.5 on page 111).
• Use the IPv6 LAN screen to configure the IPv6 address for your EMG2926-Q10A on the LAN
(Section 12.6 on page 112).
12.3 What You Need To Know
The actual physical connection determines whether the EMG2926-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 72 LAN and WAN IP Addresses
The LAN parameters of the EMG2926-Q10A in router mode are preset in the factory with the
following values:
• IPv4 address of 192.168.0.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.0.33.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS
server address(es), read the embedded Web Configurator help regarding what fields need to be
configured.
12.3.1 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The EMG2926-Q10A supports three logical LAN interfaces via its single physical
Ethernet interface with the EMG2926-Q10A itself as the gateway for each LAN network.

DHCP Server
13.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the EMG2926-Q10A’s LAN
as a DHCP server or disable it. When configured as a server, the EMG2926-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.
13.1.1 What You Can Do
• Use the General screen to enable the DHCP server (Section 13.2 on page 114).
• Use the Advanced screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 13.3 on page 114).
• Use the Client List screen to view the current DHCP client information (Section 13.4 on page
116).
13.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
LAN TCP/IP
The EMG2926-Q10A has built-in DHCP server capability that assigns IP addresses and DNS servers
to systems that support DHCP client capability.
IP Pool Setup
The EMG2926-Q10A is pre-configured with a pool of 32 IP addresses starting from 192.168.0.33 to
192.168.0.64. This configuration leaves 31 IP addresses (excluding the EMG2926-Q10A itself) in
the lower range (192.168.0.2 to 192.168.0.32) for other server computers, for instance, servers for
mail, FTP, TFTP, web, etc., that you may have.
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
to the DHCP Client List screen.

NAT
14.1 Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in
a packet. For example, the source address of an outgoing packet, used within one network is
changed to a different IP address known within another network.
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 192.168.0.35 to a third (C in the example).
You assign the LAN IP addresses to the devices (A to D) connected to your EMG2926-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 EMG2926-Q10A,
which is 192.168.0.1.

This chapter discusses how to configure NAT on the EMG2926-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 EMG2926-Q10A.
14.1.1 What You Can Do
• Use the General screen to enable NAT (Section 14.2 on page 120).
EMG2926-Q10A User’s Guide

Chapter 14 NAT
• Use the Port Forwarding screen to set a default server and change your EMG2926-Q10A’s port
forwarding settings to forward incoming service requests to the server(s) on your local network
(Section 14.3 on page 121).
• Use the Port Trigger screen to change your EMG2926-Q10A’s trigger port settings (Section
14.5.3 on page 127).
14.1.2 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 EMG2926-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.
Table 50 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.
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

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 EMG2926-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 IP 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
EMG2926-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.

14.3 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 EMG2926-Q10A’s port forwarding settings, click Network > NAT >
Port Forwarding. The screen appears as shown.
Note: If you do not assign a Default Server, the EMG2926-Q10A discards all packets
received for ports that are not specified in this screen or remote management.

14.5 Technical Reference
The following section contains additional technical information about the EMG2926-Q10A features
described in this chapter.
14.5.1 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 Forwarding 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.
14.5.2 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 192.168.0.35 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.
EMG2926-Q10A User’s Guide
126
Chapter 14 NAT
Figure 85 Multiple Servers Behind NAT Example
14.5.3 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 EMG2926-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 EMG2926-Q10A's WAN port receives a response with a specific port number and protocol
("incoming" port), the EMG2926-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.
14.5.4 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.

Real Audio Server
Port 7070
Jane requests a file from the Real Audio server (port 7070).
EMG2926-Q10A User’s Guide
127
Chapter 14 NAT
Port 7070 is a “trigger” port and causes the EMG2926-Q10A to record Jane’s computer IP address.
The EMG2926-Q10A associates Jane's computer IP address with the "incoming" port range of 69707170.
The Real Audio server responds using a port number ranging between 6970-7170.
The EMG2926-Q10A forwards the traffic to Jane’s computer IP address.
Only Jane can connect to the Real Audio server until the connection is closed or times out. The
EMG2926-Q10A times out in three minutes with UDP (User Datagram Protocol), or two hours with
TCP/IP (Transfer Control Protocol/Internet Protocol).
14.5.5 Two Points To Remember About Trigger Ports
Trigger events only happen on data that is coming from inside the EMG2926-Q10A and going to the
outside.
If an application needs a continuous data stream, that port (range) will be tied up so that another
computer on the LAN can’t trigger it.

Static Route
16.1 Overview
This chapter shows you how to configure static routes for your EMG2926-Q10A.
The EMG2926-Q10A usually uses the default gateway to route outbound traffic from computers on
the LAN to the Internet. To have the EMG2926-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 EMG2926-Q10A’s LAN
interface. The EMG2926-Q10A routes most traffic from A to the Internet through the EMG2926Q10A’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.

Use these screens to enable and configure the firewall that protects your EMG2926-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).

Chapter 17 Firewall
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 EMG2926-Q10A Firewall
The EMG2926-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 Firewall and then click the Enable Firewall check box).
The EMG2926-Q10A's purpose is to allow a private Local Area Network (LAN) to be securely
connected to the Internet. The EMG2926-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 EMG2926-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 EMG2926-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
Change the default password via Web Configurator.
Think about access control before you connect to the network in any way, including attaching a
modem to the port.

Limit who can access your router.
Don'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.
For 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.
Protect against IP spoofing by making sure the firewall is active.
Keep the firewall in a secured (locked) room.

Content Filtering
18.1 Overview
This chapter provides a brief overview of content filtering using the embedded web GUI.
Internet content filtering allows you to create and enforce Internet access policies tailored to your
needs. Content filtering is the ability to block certain web features or specific URL keywords.
18.1.1 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Content Filtering Profiles
Content filtering allows you to block certain web features, such as cookies, and/or block access to
specific web sites. For example, you can configure one policy that blocks John Doe’s access to arts
and entertainment web pages.
A content filtering profile conveniently stores your custom settings for the following features.
Keyword Blocking URL Checking
The EMG2926-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 EMG2926-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 EMG2926-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”.

Web Proxy
A server that acts as an intermediary between a user and the Internet to provide
security, administrative control, and caching service. When a proxy server is located on
the WAN it is possible for LAN users to circumvent content filtering by pointing to this
proxy server.
Enable URL
Keyword Blocking
The EMG2926-Q10A can block Web sites with URLs that contain certain keywords in the
domain name or IP address. For example, if the keyword "bad" was enabled, all sites

18.3 Technical Reference
The following section contains additional technical information about the EMG2926-Q10A features
described in this chapter.
18.3.1 Customizing Keyword Blocking URL Checking
You can use commands to set how much of a website’s URL the content filter is to check for
keyword blocking. See the appendices for information on how to access and use the command
interpreter.
Domain Name or IP Address URL Checking
By default, the EMG2926-Q10A checks the URL’s domain name or IP address when performing
keyword blocking.
This means that the EMG2926-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 EMG2926-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/.
Use the ip urlfilter customize actionFlags 6 [disable | enable] command to extend (or
not extend) the keyword blocking search to include the URL's full path.
File Name URL Checking
Filename URL checking has the EMG2926-Q10A check all of the characters in the URL.
For example, filename URL checking searches for keywords within the URL www.zyxel.com.tw/
news/pressroom.php.
Use the ip urlfilter customize actionFlags 8 [disable | enable] command to extend (or
not extend) the keyword blocking search to include the URL's complete filename.

StreamBoost Management
21.1 Overview
The EMG2926-Q10A supports the new StreamBoost technology, introduced by Qualcomm, to
redistributes traffic over the EMG2926-Q10A for the best possible performance in a home network.
At the time of writing, the StreamBoost feature is disabled on the EMG2926-Q10A.
Streamboost is smart Quality of Service (QoS). Streamboost detects traffic flows and applies traffic
shaping polcies automatically. It gives each device and each application the priority and provides
the exact amount of bandwidth they need at a given time. This helps free up bandwidth for other
applications or connected deivces. If there is not enough bandwidth for optimal performance,
Streamboost makes sure the application or device has the minimum acceptable bandwidth which is
determined according to the StreamBoost’s cloud-based database.
Real-time application traffic (such as on-line games or communications) and video/audio streaming
are given the highest priority. Downloads or torrent files are classified as best effort and placed
lower than general network traffic (general browsing).
In the figure below, the StreamBoost-enabled EMG2926-Q10A differentiates incoming traffic flows
going from the LAN device (A) or wireless device (B) to the Internet. It shapes traffic and gives
priority and allocate bandwidth according to traffic types.

22.6 SNMP
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your EMG2926-Q10A supports SNMP agent functionality, which allows a
manager station to manage and monitor the EMG2926-Q10A through the network. The EMG2926Q10A supports SNMP version one (SNMPv1) and version two (SNMPv2c). The next figure illustrates
an SNMP management operation.

Chapter 22 Remote Management
Figure 107 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 EMG2926Q10A). 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.
To change your EMG2926-Q10A’s SNMP settings, click Management > Remote MGMT > SNMP.

Universal Plug-and-Play (UPnP)
23.1 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.
23.2 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.
23.2.1 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.
23.2.2 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 EMG2926-Q10A allows multicast messages on the LAN only.
EMG2926-Q10A User’s Guide

Chapter 24 USB Media Sharing
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 EMG2926-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 EMG2926-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
EMG2926-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.
24.4 Before You Begin
Make sure the EMG2926-Q10A is connected to your network and turned on.
Connect the USB device to one of the EMG2926-Q10A’s USB ports.
The EMG2926-Q10A detects the USB device and makes its contents available for browsing. If you
