Chapter 1 IntroductionEMG6765-Q10A User’s Guide141.4 Good Habits for Managing the EMG6765-Q10ADo 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-Q10AIf 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 Button1Make 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 ButtonYour 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).

Chapter 1 IntroductionEMG6765-Q10A User’s Guide152Press 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 48.1.6 Front PanelThe LED indicators are located on the front panel.

Chapter 6 TutorialsEMG6765-Q10A User’s Guide446.5 Configuring Static Route for Routing to Another NetworkIn 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 TutorialsEMG6765-Q10A User’s Guide45This 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.

Chapter 8 WANEMG6765-Q10A User’s Guide62MulticastTraditionally, 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 ExampleIn 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).

Chapter 8 WANEMG6765-Q10A User’s Guide678.4.1.2 PPPoE EncapsulationThe 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.IPv6 DNS serverThis is not available when you select IPv4 Only in the IPv6/IPv4 field.Obtain IPv6 DNS info AutomaticallySelect this to have the EMG6765-Q10A get the IPv6 DNS server addresses from the ISP automatically.Use the following Static DNS IPv6 AddressSelect this to have the EMG6765-Q10A use the IPv6 DNS server addresses you configure manually.

EMG6765-Q10A User’s Guide72CHAPTER 9Wireless LAN9.1 OverviewThis 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 NetworkThe 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 LANEMG6765-Q10A User’s Guide739.1.1 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 KnowEvery 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 OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.SSIDNormally, 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 LANEMG6765-Q10A User’s Guide74MAC Address FilterEvery 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 AuthenticationYou 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 WLANGuest 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.

Chapter 9 Wireless LANEMG6765-Q10A User’s Guide75Figure 31 Guest Wireless LAN NetworkGuest WLAN BandwidthThe Guest WLAN Bandwidth function allows you to restrict the maximum bandwidth for the guest 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.)Figure 32 Example: Bandwidth for Different NetworksWPSWi-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.

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.802.11 Mode If you are in the Wireless LAN 2.4G > General screen, you can select from the following:•802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the EMG6765-Q10A.

EMG6765-Q10A User’s Guide109CHAPTER 13NAT13.1 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 ExampleThis 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 NATEMG6765-Q10A User’s Guide110• 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 KnowThe following terms and concepts may help as you read through this chapter.Inside/OutsideThis 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 DoesIn 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 DefinitionsITEM DESCRIPTIONInside 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 NATEMG6765-Q10A User’s Guide111How NAT WorksEach 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. The following figure illustrates this.Figure 59 How NAT Works13.2 GeneralUse this screen to enable NAT and set a default server.

Chapter 13 NATEMG6765-Q10A User’s Guide112The following table describes the labels in this screen.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.Refer to Appendix B on page 200 for port numbers commonly used for particular services.Table 45 Network > NAT > GeneralLABEL DESCRIPTIONNetwork Address Translation (NAT)Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).

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.

Chapter 13 NATEMG6765-Q10A User’s Guide117Figure 64 Multiple Servers Behind NAT Example13.5.3 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 NATEMG6765-Q10A User’s Guide118Figure 65 Trigger Port Forwarding Process: Example1Jane 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 Ports1Trigger 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.

EMG6765-Q10A User’s Guide121CHAPTER 15Static Route15.1 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.Figure 67 Example of Static Routing Topology15.2 IP Static Route Screen Click Network > Static Route to open the Static Route screen.

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).Figure 73 Default Firewall Action17.1.1 What You Can Do• Use the General screen to enable or disable the EMG6765-Q10A’s firewall (Section 17.2 on page 129).• Use the Services screen enable service blocking, enter/delete/modify the services you want to block and the date/time you want to block them (Section 17.3 on page 129).17.1.2 What You Need To KnowThe following terms and concepts may help as you read through this chapter.

Chapter 17 FirewallEMG6765-Q10A User’s Guide128What 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 FirewallThe 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 Firewall1Change 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.

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 KnowThe following terms and concepts may help as you read through this chapter.Keyword Blocking URL CheckingThe 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”.20.2 Parental Control ScreenUse this screen to enable parental control, view the parental control rules and schedules.Click Configuration > Security > Parental Control to open the following screen.

EMG6765-Q10A User’s Guide142CHAPTER 21Bandwidth Management21.1 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 KnowThe following terms and concepts may help as you read through this chapter.QoS versus CoSQoS 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 ManagementEMG6765-Q10A User’s Guide143CoS 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 MarkingIn 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 ShapingBursty 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 PolicingTraffic 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.TrafficTimeTraffic RateTrafficTimeTraffic Rate(Before Traffic Shaping) (After Traffic Shaping)TrafficTimeTraffic RateTrafficTimeTraffic Rate(Before Traffic Policing) (After Traffic Policing)

Table 62 Management > Bandwidth MGMT > GeneralLABEL DESCRIPTIONQoSQoS State Select the Enable check box to turn on QoS to improve your network performance. 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.

Chapter 21 Bandwidth ManagementEMG6765-Q10A User’s Guide151IEEE 802.1p specifies the user priority field and defines up to eight separate traffic types. The following table describes the traffic types defined in the IEEE 802.1d standard (which incorporates the 802.1p). DiffServ QoS is used to prioritize source-to-destination traffic flows. All packets in the flow are given the same priority. You can use CoS (class of service) to give different priorities to different packet types.DiffServ (Differentiated Services) is a class of service (CoS) model that marks packets so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the level of service desired. This allows the intermediary DiffServ-compliant network devices to handle the packets differently depending on the code points without the need to negotiate paths or remember state information for every flow. In addition, applications do not have to request a particular service or give advanced notice of where the traffic is going. DSCP and Per-Hop Behavior DiffServ defines a new Differentiated Services (DS) field to replace the Type of Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define up to 64 service levels. The following figure illustrates the DS field. DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping.The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different kinds of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.IP PrecedenceSimilar 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 Table 67 IEEE 802.1p Priority Level and Traffic TypePRIORITY LEVEL TRAFFIC TYPELevel 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.DSCP (6 bits) Unused (2 bits)

Chapter 21 Bandwidth ManagementEMG6765-Q10A User’s Guide152are 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 AssignmentIf 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.Table 68 Internal Layer2 and Layer3 QoS MappingPRIORITY QUEUELAYER 2 LAYER 3IEEE 802.1P USER PRIORITY (ETHERNET PRIORITY)TOS (IP PRECEDENCE) DSCP IP PACKET LENGTH (BYTE)0 1 0 000000122 0 0 000000 >11003 3 1 001110001100001010001000250~11004 4 2 0101100101000100100100005 5 3 011110011100011010011000<2506 6 4 1001101001001000101000005 1011101010007 7 6 1100001110007

Chapter 21 Bandwidth ManagementEMG6765-Q10A User’s Guide153Token BucketThe 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 ManagementEMG6765-Q10A User’s Guide154• 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.

EMG6765-Q10A User’s Guide155CHAPTER 22Universal 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 KnowUPnP 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 TraversalUPnP 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 mappingsWindows 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 UPnPThe 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 23 USB Media SharingEMG6765-Q10A User’s Guide163Workgroup nameThis 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 SystemsA 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/CIFSCommon 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). SambaSMB 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.
