CHAPTER 1
Introduction
1.1 Overview
This chapter introduces the main features and applications of the EMG6765-Q10A.
The EMG6765-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.
The EMG6765-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
A range of services such as a firewall and content filtering are also available for secure Internet
computing. There is one USB 2.0 port on the side panel of your EMG6765-Q10A, and the other one is on
the rear panel of your EMG6765-Q10A. You can connect USB (version 2.0 or lower) memory sticks, USB
hard drives, or USB devices for file sharing. The EMG6765-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.
Chapter 1 Introduction
EMG6765-Q10A User’s Guide
13
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 EMG6765-Q10A.
The EMG6765-Q10A also comes with one coaxial port that supports MoCA (Multimedia over Coax
Alliance) technology. Use MoCA technology to extend your network through a coaxial connection to
another MoCA device and/or a device connected to a MoCA adapter.
Use a (supported) web browser to manage the EMG6765-Q10A.
1.2 Applications
You can have the following networks with the EMG6765-Q10A:
•Wired. You can connect network devices via the Ethernet ports of the EMG6765-Q10A so that they
can communicate with each other and access the Internet.
•Wireless. Wireless clients can connect to the EMG6765-Q10A to access network resources. You can
use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-
compatible device.
•WAN. Connect to a broadband modem/router for Internet access.
Figure 2 EMG6765-Q10A Networks
1.3 Ways to Manage the EMG6765-Q10A
Use any of the following methods to manage the EMG6765-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 EMG6765-Q10A.
• Web Configurator. This is recommended for everyday management of the EMG6765-Q10A using a
(supported) web browser.

1.4 Good Habits for Managing the EMG6765-Q10A
Do the following things regularly to make the EMG6765-Q10A more secure and to manage the
EMG6765-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 EMG6765-Q10A to its factory default settings. If you backed up
an earlier configuration file, you would not have to totally re-configure the EMG6765-Q10A. You could
simply restore your last configuration.
1.5 Resetting the EMG6765-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 EMG6765-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”, the password will be reset to the back-label default key, and the IP address will be reset to
“192.168.1.1” (router mode).
1.5.1 RESET Button
1Make sure the power LED is on.
2Press and hold the RESET button for more than 5 seconds, the power LED begins flashing.
3Release the RESET button. The EMG6765-Q10A reloads factory-default settings and begins to reboot.
1.5.2 The WPS Button
Your EMG6765-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.
You can use the WPS button ( ) on the side panel of the EMG6765-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 one second and release it. Press the WPS button on another WPS-
enabled device within range of the EMG6765-Q10A.
Note: You must activate WPS on the EMG6765-Q10A and on another wireless device within
two minutes of each other.
For more information on using WPS, see Section 6.8 on page 48.

6.5 Configuring Static Route for Routing to Another
Network
In order to extend your Intranet and control traffic flowing directions, you may connect a router to the
EMG6765-Q10A’s LAN. The router may be used to separate two department networks. This tutorial shows
how to configure a static routing rule for two network routings.
In the following figure, router R is connected to the EMG6765-Q10A’s LAN. R connects to two networks,
N1 (192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from computer A (in N1 network)
to computer B (in N2 network), the traffic is sent to the EMG6765-Q10A’s WAN default gateway by
default. In this case, B will never receive the traffic.
You need to specify a static routing rule on the EMG6765-Q10A to specify R as the router in charge of
forwarding traffic to N2. In this case, the EMG6765-Q10A routes traffic from A to R and then R routes the
traffic to B.
Chapter 6 Tutorials
EMG6765-Q10A User’s Guide

This tutorial uses the following example IP settings:
To configure a static route to route traffic from N1 to N2:
1Log into the EMG6765-Q10A’s Web Configurator in advanced mode.
2Click Configuration > Network > Static Route.
3Click Add Static Route in the Static Route screen.
4Configure the Add Static Route screen using the following settings:
4a Select Enable in the Static Route field. Enter the Route Name as R.
4b Type 192.168.10.0 and subnet mask 255.255.255.0 for the destination, N2.
4c Select Enable in the Use Gateway IP Address field. Type 192.168.1.253 (R’s N1 address) in the
Gateway IP Address field.
4d Click Apply.

Now B should be able to receive traffic from A. You may need to additionally configure B’s firewall
settings to allow specific traffic to pass through.
6.6 Access the EMG6765-Q10A Using DDNS
If you connect your EMG6765-Q10A to the Internet and it uses a dynamic WAN IP address, it is
inconvenient for you to manage the device from the Internet. The EMG6765-Q10A’s WAN IP address
changes dynamically. Dynamic DNS (DDNS) allows you to access the EMG6765-Q10A using a domain
name.
To use this feature, you have to apply for DDNS service at, for example, www.dyndns.org.
This tutorial covers:
•Registering a DDNS Account on www.dyndns.org
•Configuring DDNS on Your EMG6765-Q10A
•Testing the DDNS Setting
Note: If you have a private WAN IP address, then you cannot use DDNS.
6.6.1 Registering a DDNS Account on www.dyndns.org
1Open a browser and type http://www.dyndns.org.
2Apply for a user account. This tutorial uses UserName1 and 5 as the username and password.
3Log into www.dyndns.org using your account.
4Add a new DDNS host name. This tutorial uses the following settings as an example.
• Hostname: zyxelrouter.dyndns.org
• Service Type: Host with IP address
• IP Address: Enter the WAN IP address that your EMG6765-Q10A is currently using. You can find the IP
address on the EMG6765-Q10A’s Web Configurator Status page.
Then you will need to configure the same account and host name on the EMG6765-Q10A later.
Chapter 6 Tutorials
EMG6765-Q10A User’s Guide

6.6.2 Configuring DDNS on Your EMG6765-Q10A
Configure the following settings in the Network Setting > DNS > Dynamic DNS screen.
•Select Enable Dynamic DNS.
•Select www.DynDNS.com as the service provider.
•Type zyxelrouter.dyndns.org in the Host Name field.
• Enter the user name (UserName1) and password (5).
Click Apply.
6.6.3 Testing the DDNS Setting
Now you should be able to access the EMG6765-Q10A from the Internet. To test this:
1Open a web browser on the computer (using the IP address a.b.c.d) that is connected to the Internet.
2Type http://zyxelrouter.dyndns.org and press [Enter].
3The EMG6765-Q10A’s login page should appear. You can then log into the EMG6765-Q10A and
manage it.
6.7 Configuring the MAC Address Filter
Thomas noticed that his daughter Josephine spends too much time surfing the web and downloading
media files. He decided to prevent Josephine from accessing the Internet so that she can concentrate
on preparing for her final exams.
Josephine’s computer connects wirelessly to the Internet through the EMG6765-Q10A. Thomas decides
to use the Configuration > Network > Wireless LAN 2.4G or 5G > MAC Filter screen to grant wireless
network access to his computer but not to Josephine’s computer.
Chapter 6 Tutorials
EMG6765-Q10A User’s Guide

Thomas can also grant access to the computers of other members of his family and friends. However,
Josephine and others not listed in this screen will no longer be able to access the Internet through the
EMG6765-Q10A.
6.8 Using Multiple SSIDs on the EMG6765-Q10A
You can configure more than one SSID on a EMG6765-Q10A. See Section 9.4 on page 81.
This allows you to configure multiple independent wireless networks on the EMG6765-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 EMG6765-Q10A represents a different access point/wireless network to
wireless clients in the network.
Chapter 6 Tutorials
EMG6765-Q10A User’s Guide
49
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 EMG6765-Q10A (such as a
printer).
For example, you may set up three wireless networks (A, B and C) in your office. A is for workers, B is for
guests and C is specific to a VoIP device in the meeting room.
6.8.1 Configuring Security Settings of Multiple SSIDs
The EMG6765-Q10A is in router mode by default.
This example shows you how to configure the SSIDs with the following parameters on your EMG6765-
Q10A (in router mode).
1Connect your computer to the LAN port of the EMG6765-Q10A using an Ethernet cable.
2The default IP address of the EMG6765-Q10A in router mode is “192.168.1.1”. In this case, your computer
must have an IP address in the range between “192.168.1.2” and “192.168.1.254”.
3Click Start > Run on your computer in Windows. Type “cmd” in the dialog box. Enter “ipconfig” to show
your computer’s IP address. If your computer’s IP address is not in the correct range then see Appendix
B on page 200 for information on changing your computer’s IP address.
4After you’ve set your computer’s IP address, open a web browser such as Internet Explorer and type
“http://192.168.1.1” as the web address in your web browser.

CHAPTER 8
WAN
8.1 Overview
This chapter discusses the EMG6765-Q10A’s WAN screens. Use these screens to configure your EMG6765-
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 24 LAN and WAN
8.2 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 8.4 on page 62).
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 EMG6765-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 over
Chapter 8 WAN
EMG6765-Q10A User’s Guide
61
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 EMG6765-Q10A, which makes it accessible from an outside
network. It is used by the EMG6765-Q10A to communicate with other devices in other networks. It can
be static (fixed) or dynamically assigned by the ISP each time the EMG6765-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 EMG6765-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 EMG6765-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 Factory Default to
select the factory assigned default MAC Address.
Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of the
computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be
copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the
WAN Port.
Chapter 8 WAN
EMG6765-Q10A User’s Guide

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 25 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 EMG6765-Q10A supports both IGMP version 1
(IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the EMG6765-Q10A queries all directly connected networks to gather group membership.
After that, the EMG6765-Q10A periodically updates this information. IP multicasting can be enabled/
disabled on the EMG6765-Q10A WAN interface in the Web Configurator (WAN). Select None to disable
IP multicasting on these interfaces.

IPv6 Tunneling
The EMG6765-Q10A uses tunnel interfaces in Generic Routing Encapsulation (GRE), IPv6 in IPv4, and 6to4
tunnels. GRE tunnels encapsulate a wide variety of network layer protocol packet types inside IP tunnels. A GRE
tunnel serves as a virtual point-to-point link between the EMG6765-Q10A and another router over an IPv4
network.
IPv6 Tunneling Enable IPv6 Rapid Deployment (6rd) to tunnel IPv6 traffic from the local network through the
ISP’s IPv4 network. The EMG6765-Q10A generates a global IPv6 prefix from its IPv4 WAN
address and tunnels IPv6 traffic to the ISP’s Border Relay router to connect to the native IPv6
Internet. The local network can also use IPv4 services. The EMG6765-Q10A uses its configured
IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet.
Enable 6to4 to enable IPv6 packets to cross IPv4 networks. the EMG6765-Q10A should get a
public IPv4 address for the WAN. The EMG6765-Q10A adds an IPv4 IP header to an IPv6
packet when transmitting the packet to the Internet. In reverse, the EMG6765-Q10A removes
the IPv4 header from an IPv6 packet when receiving it from the Internet.
Enable 6in4 if the EMG6765-Q10A has a public IPv4 IP address given from your ISP and you
want to transmit your Ipv6 packets to one and only one remote site whose LAN network is
also an IPv6 network.
This is available only when you select IPv4 Only in the IPv6/IPv4 field.

8.4.1.2 PPPoE Encapsulation
The EMG6765-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.
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 EMG6765-Q10A (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the EEMG6765-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
9.1 Overview
This chapter discusses how to configure the wireless network settings in your EMG6765-Q10A. The
EMG6765-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 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 EMG6765-Q10A is the AP.
Chapter 9 Wireless LAN
EMG6765-Q10A User’s Guide
73
9.1.1 What You Can Do
• Use the General screen to turn the wireless connection on or off, set up wireless security between the
EMG6765-Q10A and the wireless clients, and make other basic configuration changes (Section 9.2 on
page 76).
• Use the More AP screen to set up multiple wireless networks on your EMG6765-Q10A (Section 9.4 on
page 81).
• Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the EMG6765-Q10A (Section 9.5 on page 84).
• Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 9.6 on
page 86).
• Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 9.7 on page
87).
• Use the WPS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 9.8 on page 87).
• Use the WPS Station screen to add a wireless station using WPS (Section 9.9 on page 89).
• Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 9.10 on
page 89).
• Use the Airtime Management screen to assign available airtime and bandwidth to interfaces and
hosts (Section 9.11 on page 90).
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
EMG6765-Q10A User’s Guide
74
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.
Guest WLAN
Guest WLAN allows you to set up a wireless network where users can access to Internet via the
EMG6765-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.
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.

wireless network. Additionally, you can also define bandwidth for your home or office network. An
example is shown next to define maximum bandwidth for your networks (A is Guest WLAN and N is home
or company network.)

WPS
Wi-Fi Protected Setup (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. 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.

Channel
This displays the channel the EMG6765-Q10A is currently using.
Channel Width Select the wireless channel width used by EMG6765-Q10A.
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 Auto 20/40 MHz or
Auto 20/40/80 MHz to allow the EMG6765-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.

EMG6765-Q10A.
• Scenario 1. All active SSIDs can use all of the EMG6765-Q10A’s airtime. Make sure the airtime total is
100%. If you don’t allocate all airtime to active SSIDs, the remaining airtime will be lost.
Percentage Enter the percentage of time for the transmissions on this Wi-Fi station.
Note: The airtime per Wi-Fi Station is proportional to the airtime of the SSID
this station is connected to.
Add & Modify Click this to add or modify a Wi-Fi station airtime rule to the EMG6765-Q10A.

•Scenario 2. If Home SSID and IPTV SSID take 100% of the airtime in Manual, no Airtime (0%) is allocated
to Public SSID, whether this SSID is in Auto or Manual. In this cases Manual will have priority over Auto.
• Scenario 3. If all active SSIDs are in Auto, the EMG6765-Q10A will assign equal percentages of airtime
to all active SSIDs.
• Scenario 4. Wi-Fi Stations airtime is proportional to the total airtime of the SSID they belong to. In this
scenario Wi-Fi Station A will take up 50% of the 40% assigned to Home SSID, which would be 40%*50%=
20%. Whereas Wi-Fi Station B will use 50% of the 10% assigned to Public SSID, which would be
10%*50%= 5%.

CHAPTER 10
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 47 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 IP screen to change the IP address for your EMG6765-Q10A (Section 10.4 on page 96).
• Use the IP Alias screen to have the EMG6765-Q10A apply IP alias to create LAN subnets (Section 10.5
on page 96).
• Use the IPv6 LAN screen to configure the IPv6 address for your EMG6765-Q10A on the LAN (Section
10.6 on page 97).
• Use the IGMP Snooping screen to enable IGMP Snooping and configure IGMP modes. (Section 10.7
on page 98).

10.3 What You Need To Know
The actual physical connection determines whether the EMG6765-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 48 LAN and WAN IP Addresses
The LAN parameters of the EMG6765-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 EMG6765-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 EMG6765-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 EMG6765-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 EMG6765-Q10A supports three logical LAN interfaces via its single physical Ethernet
interface with the EMG6765-Q10A itself as the gateway for each LAN network.

CHAPTER 11
MoCA
11.1 Overview
MoCA (Multimedia over Coax Alliance) is an industry standard organization, which created a standard
for transferring data and multimedia content over the existing coaxial wires in your home. Data
communication and audio/video streaming are allowed at the same time. The EMG6765-Q10A (A)
automatically sets up a MoCA network when multiple MoCA devices (nodes) are powered on and
connected with a coaxial cable.
The EMG6765-Q10A supports MoCA 2.0 and is backward compatible with MoCA 1.1. The MoCA 1.1
technology provides 175 Mbps net throughputs (270 Mbps PHY rate) and operates in the 500 to 1500
MHz frequency range. MoCA 2.0 in turbo mode offers actual data rates of up to 1 Gbps MAC
throughputs and operates in the 500 to 1650 MHz operating frequency range. MoCA 2.0 also supports
improved packet error rate (PER) and two new power saving modes: Standby (reduced power) and
Sleep (minimum power).
The EMG6765-Q10A should be connected to the WAN via Ethernet, then the coaxial network in your
home will only work as a LAN.

CHAPTER 13
NAT
13.1 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 EMG6765-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 EMG6765-Q10A, which is 192.168.1.1.
Figure 58 NAT Example
This chapter discusses how to configure NAT on the EMG6765-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 EMG6765-Q10A.
13.1.1 What You Can Do
• Use the General screen to enable NAT (Section 13.2 on page 111).
• Use the Port Forwarding screen to set a default server and change your EMG6765-Q10A’s port
forwarding settings to forward incoming service requests to the server(s) on your local network
(Section 13.3 on page 112).
Chapter 13 NAT
EMG6765-Q10A User’s Guide

• Use the Port Trigger screen to change your EMG6765-Q10A’s trigger port settings (Section 13.5.3 on
page 117).
13.1.2 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 EMG6765-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
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 EMG6765-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).
Table 44 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.
Chapter 13 NAT
EMG6765-Q10A User’s Guide
111
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 EMG6765-Q10A keeps track of the
original addresses and port numbers so incoming reply packets can have their original values restored.

13.3 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 EMG6765-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 EMG6765-Q10A discards all packets received
for ports that are not specified in this screen or remote management.

13.5 Technical Reference
The following section contains additional technical information about the EMG6765-Q10A features
described in this chapter.
13.5.1 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.
13.5.2 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 64 Multiple Servers Behind NAT Example
13.5.3 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 EMG6765-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
EMG6765-Q10A's WAN port receives a response with a specific port number and protocol ("incoming"
port), the EMG6765-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.
13.5.4 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.
Chapter 13 NAT

118
Figure 65 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 EMG6765-Q10A to record Jane’s computer IP address. The
EMG6765-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 EMG6765-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
EMG6765-Q10A times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP
(Transfer Control Protocol/Internet Protocol).
13.5.5 Two Points To Remember About Trigger Ports
1Trigger events only happen on data that is coming from inside the EMG6765-Q10A and going to the
outside.
2If an application needs a continuous data stream, that port (range) will be tied up so that another
computer on the LAN can’t trigger it.

Static Route
15.1 Overview
This chapter shows you how to configure static routes for your EMG6765-Q10A.
The EMG6765-Q10A usually uses the default gateway to route outbound traffic from computers on the
LAN to the Internet. To have the EMG6765-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 EMG6765-Q10A’s LAN interface.
The EMG6765-Q10A routes most traffic from A to the Internet through the EMG6765-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.

Firewall
17.1 Overview
Use these screens to enable and configure the firewall that protects your EMG6765-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 EMG6765-Q10A Firewall
The EMG6765-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
EMG6765-Q10A's purpose is to allow a private Local Area Network (LAN) to be securely connected to
the Internet. The EMG6765-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 EMG6765-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 EMG6765-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.
3Limit who can access your router.
Chapter 17 Firewall
EMG6765-Q10A User’s Guide

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.

CHAPTER 20
Parental Control
20.1 Overview
Parental controls allow you to block specific URLs. You can also define time periods and days during
which the EMG6765-Q10A performs parental control on a specific user.
20.1.1 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Keyword Blocking URL Checking
The EMG6765-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 EMG6765-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 EMG6765-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”.

CHAPTER 21
Bandwidth Management
21.1 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 EMG6765-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 EMG6765-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.
21.1.1 What You Can Do in this Chapter
• The General screen lets you enable or disable QoS and set the upstream bandwidth (Section 21.3 on
page 144).
• The Queue Setup screen lets you configure QoS queue assignment (Section 21.4 on page 145).
• The Class Setup screen lets you add, edit or delete QoS classifiers (Section 21.5 on page 147).
21.2 What You Need to Know
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 similar types of
traffic together and treating each type as a class. You can use CoS to give different priorities to different
packet types.
Chapter 21 Bandwidth Management
EMG6765-Q10A User’s Guide
143
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 EMG6765-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 EMG6765-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 specify actions which
are performed on the colored packets. See Section 21.6 on page 150 for more information on each
metering algorithm.

WAN Managed
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 EMG6765-
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 EMG6765-Q10A to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the EMG6765-Q10A automatically sets this number to be 95% of the
WAN interfaces’ actual upstream transmission speed.
LAN Managed
Downstream
Bandwidth
Enter the amount of downstream bandwidth for the LAN interfaces (including WLAN) that you
want to allocate using QoS.
The recommendation is to set this speed to match the WAN interfaces’ actual transmission
speed. For example, set the LAN managed downstream bandwidth to 100000 kbps if you 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 EMG6765-Q10A to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the EMG6765-Q10A automatically sets this to the LAN interfaces’
maximum supported connection speed.

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

LEVEL TRAFFIC TYPE
Level 7 Typically used for network control traffic such as router configuration messages.
Level 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay).
Level 5 Typically used for video that consumes high bandwidth and is sensitive to jitter.
Level 4 Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network
Architecture) transactions.
Level 3 Typically used for “excellent effort” or better than best effort and would include important business
traffic that can tolerate some delay.
Level 2 This is for “spare bandwidth”.
Level 1 This is typically used for non-critical “background” traffic such as bulk transfers that are allowed but
that should not affect other applications and users.
Level 0 Typically used for best-effort traffic.

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 EMG6765-Q10A, the EMG6765-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.
The following table shows you the internal layer-2 and layer-3 QoS mapping on the EMG6765-Q10A. On
the EMG6765-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 EMG6765-Q10A stops transmitting until enough tokens are
generated.
• If not enough tokens are available, the EMG6765-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 EMG6765-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).
Chapter 21 Bandwidth Management
EMG6765-Q10A User’s Guide
154
• 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 EMG6765-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 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 EMG6765-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 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.
Chapter 22 Universal Plug-and-Play (UPnP)
EMG6765-Q10A User’s Guide
156
When a UPnP device joins a network, it announces its presence with a multicast message. For security
reasons, the EMG6765-Q10A allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.

USB Media Sharing
23.1 Overview
This chapter describes how to configure the media sharing settings on the EMG6765-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 EMG6765-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 EMG6765-Q10A media server enables you to:
• Publish all folders for everyone to play media files in the USB storage device connected to the
EMG6765-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.
The following figure is an overview of the EMG6765-Q10A’s media server feature. DLNA devices A and B
can access and play files on a USB device (C) which is connected to the EMG6765-Q10A (D).

23.2 What You Can Do
• Use the DLNA screen to use the EMG6765-Q10A as a media server and allow DLNA-compliant devices
to play media files stored in the attached USB device (Section 23.5 on page 164).
• Use the SAMBA screen to enable file-sharing via the EMG6765-Q10A using Windows Explorer or the
workgroup name. This screen also allow you to configure the workgroup name and create user
accounts (Section 23.6 on page 164).
• Use the FTP screen to allow file sharing via the EMG6765-Q10A using FTP and create user accounts
(Section 23.7 on page 166).
23.3 What You Need To Know
DLNA
The Digital Living Network Alliance (DLNA) is a group of personal computer and electronics companies
that works to make products compatible in a home network. DLNA clients play files stored on DLNA
servers. The EMG6765-Q10A can function as a DLNA-compliant media server and stream files to DLNA-
compliant media clients without any configuration.

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 EMG6765-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 EMG6765-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 EMG6765-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.
23.4 Before You Begin

Speed Select the speed of the Ethernet connection on this port. The choices are Auto, 1000, 100
and 10.
Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port
automatically to obtain the connection speed that both ends support. If the peer port does
not support auto-negotiation or turns off this feature, the EMG6765-Q10A determines the
connection speed by detecting the signal on the cable and using half duplex mode.
Duplex Select the duplex mode of the Ethernet connection on this port. The choices are Auto, Full
and Half.
Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port
automatically to obtain the duplex mode that both ends support. If the peer port does not

Refer to Appendix B on page 200 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.
