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

Figure 1 Dual-Band Application 1.2 Applications You can have the following networks with the EMG3425-Q10A:

Wired. You can connect network devices via the Ethernet ports of the EMG3425-Q10A so that they can communicate with each other and access the Internet. Wireless. Wireless clients can connect to the EMG3425-Q10A to access network resources. You can use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-

compatible device. WAN. Connect to a broadband modem/router for Internet access. 1.3 Ways to Manage the EMG3425-Q10A Use any of the following methods to manage the EMG3425-Q10A. WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your EMG3425-Q10A. Web Configurator. This is recommended for everyday management of the EMG3425-Q10A using a (supported) web browser. EMG3425-Q10A Users Guide 13 Chapter 1 Introduction 1.4 Good Habits for Managing the EMG3425-Q10A Do the following things regularly to make the EMG3425-Q10A more secure and to manage the EMG3425-Q10A more effectively. Change the password. Use a password thats not easy to guess and that consists of different types of characters, such as numbers and letters. Write down the password and put it in a safe place. Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the EMG3425-Q10A to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the EMG3425-Q10A. You could simply restore your last configuration. 1.5 Resetting the EMG3425-Q10A If you forget your password or IP address, or you cannot access the Web Configurator, you will need to use the RESET button at the back of the EMG3425-Q10A to reload the factory-default configuration file. This means that you will lose all configurations that you had previously saved, the user name will be reset to supervisor or admin, the password will be reset to supervisor or 1234, and the IP address will be reset to 192.168.1.1 (router mode). 1.5.1 How to Use the RESET Button 1 Make sure the power LED is on. 2 3 Press the RESET button for one to four seconds to restart/reboot the EMG3425-Q10A. Press the RESET button for longer than five seconds to set the EMG3425-Q10A back to its factory-

default configurations. 1.6 The WPS Button Your EMG3425-Q10A supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each devices 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. EMG3425-Q10A Users Guide 14 Chapter 1 Introduction You can use the WPS button (

Set Up a Wireless Network Using WPS Connect to EMG3425-Q10A Wireless Network without WPS Using Multiple SSIDs on the EMG3425-Q10A 6.2 Set Up a Wireless Network Using WPS This section gives you an example of how to set up wireless network using WPS. This example uses the EMG3425-Q10A as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card). There are two WPS methods for creating a secure connection via the web configurator or utility. This tutorial shows you how to do both. Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 6.2.1 on page 38. This is the easier method. PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN

(Personal Identification Number) in the EMG3425-Q10As interface. See Section 6.2.2 on page 39. This is the more secure method, since one device can authenticate the other. 6.2.1 Push Button Configuration (PBC) 1 Make sure that your EMG3425-Q10A is turned on. Make sure the WIFI button (at the back panel of the EMG3425-Q10A) is pushed in, and that the device is placed within range of your notebook. 2 Make sure that you have installed the wireless client (this example uses the NWD210N) driver and utility in your notebook. 3 4 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or WPS button) Log into EMG3425-Q10As Web Configurator and press the Push Button in the Configuration >

Network > Wireless LAN 2.4G > WPS Station screen. EMG3425-Q10A Users Guide 38 Chapter 6 Tutorials Note: Your EMG3425-Q10A has a WPS button located on its panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other. Note: It doesnt matter which button is pressed first.

Use these screens to configure your EMG3425-Q10A for Internet access. A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations. Figure 25 LAN and WAN 8.2 What You Can Do Use the 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 59). 8.3 What You Need To Know The information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your EMG3425-Q10A. 8.3.1 Configuring Your Internet Connection Encapsulation Method Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP EMG3425-Q10A Users Guide 57 Chapter 8 WAN over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password (and service name) for user authentication. WAN IP Address The WAN IP address is an IP address for the EMG3425-Q10A, which makes it accessible from an outside network. It is used by the EMG3425-Q10A to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the EMG3425-Q10A tries to access the Internet. If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method). DNS Server Address Assignment Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The EMG3425-Q10A can get the DNS server addresses in the following ways. 1 2 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields. If your ISP dynamically assigns the DNS server IP addresses (along with the EMG3425-Q10As 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. EMG3425-Q10A Users Guide 58 Chapter 8 WAN Multicast Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1. Figure 26 Multicast Example In the multicast example above, systems A and D comprise one multicast group. In multicasting, the server only needs to send one data stream and this is delivered to systems A and D. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a multicast group - it is not used to carry user data. The EMG3425-Q10A supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the EMG3425-Q10A queries all directly connected networks to gather group membership. After that, the EMG3425-Q10A periodically updates this information. IP multicasting can be enabled/disabled on the EMG3425-Q10A WAN interface in the Web Configurator (WAN). Select None to disable IP multicasting on these interfaces. 8.4 Management WAN Use this screen to view, change, or add your EMG3425-Q10As Internet access settings.

Click Cancel to begin configuring this screen afresh. 8.4.1.2 PPPoE Encapsulation The EMG3425-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 EMG3425-Q10A Users Guide 63 Chapter 8 WAN

(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 EMG3425-Q10A (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the EEMG3425-Q10A does that part of the task. Furthermore, with NAT, all of the LANs computers will have access. This screen displays when you select PPPoE encapsulation.

EMG3425-Q10A Users Guide 67 CHAPTER 9 Wireless LAN 9.1 Overview This chapter discusses how to configure the wireless network settings in your EMG3425-Q10A. The EMG3425-Q10A is able to function both 2.4GHz and 5GHz network at the same time. You can have different wireless and wireless security settings for 2.4GHz and 5GHz wireless LANs. Click 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 EMG3425-Q10A is the AP. EMG3425-Q10A Users Guide 68 Chapter 9 Wireless LAN 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 EMG3425-Q10A and the wireless clients, and make other basic configuration changes (Section 9.2 on page 73). Use the More AP screen to set up multiple wireless networks on your EMG3425-Q10A (Section 9.4 on page 79). Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from connecting to the EMG3425-Q10A (Section 9.5 on page 81). Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 9.6 on page 83). Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 9.7 on page 83). Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 9.8 on page 84). Use the WPS Station screen to add a wireless station using WPS (Section 9.9 on page 86). Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 9.10 on page 86). 9.1.2 What You Should Know Every wireless network must follow these basic guidelines. Every wireless client in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentity. If two wireless networks overlap, they should use different channels. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess. This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network. EMG3425-Q10A Users Guide 69 Chapter 9 Wireless LAN MAC Address Filter Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate Users Guide or other documentation. You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings. This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network. User Authentication You can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this. For wireless networks, there are two typical places to store the user names and passwords for each user. In the AP: this feature is called a local user database or a local database. In a RADIUS server: this is a server used in businesses more than in homes. If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users. Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network. Local user databases also have an additional limitation that is explained in the next section. Encryption Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. 1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses. 2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. EMG3425-Q10A Users Guide 70 Chapter 9 Wireless LAN The types of encryption you can choose depend on the type of user authentication. (See page 70 for information about this.) Table 18 Types of Encryption for Each Type of Authentication Weakest Strongest NO AUTHENTICATION No Security Static WEP WPA-PSK WPA2-PSK RADIUS SERVER WPA WPA2 For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK. Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network. Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly. Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database. When you select WPA2 or WPA2-PSK in your EMG3425-Q10A, you can also select an option

(WPA/WPA-PSK Compatible) to support WPA/WPA-PSK as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA/WPA-PSK Compatible option in the EMG3425-Q10A. Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key. Guest WLAN Guest WLAN allows you to set up a wireless network where users can access to Internet via the EMG3425-Q10A (Z), but not other networks connected to the Z. In the following figure, a guest user can access the Internet from the guest wireless network A via Z but not the home or company network N. Note: The home or company network N and Guest WLAN network are independent networks. EMG3425-Q10A Users Guide 71 Chapter 9 Wireless LAN Figure 31 Guest Wireless LAN Network A Z N Guest WLAN Bandwidth The 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 Networks N 600 kbps 100 kbps 300 kbps A WPS WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification EMG3425-Q10A Users Guide 72 Chapter 9 Wireless LAN Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 6.2 on page 38. 9.2 General Wireless LAN Screen Use this screen to configure the SSID and wireless security of the wireless LAN. Note: If you are configuring the EMG3425-Q10A from a computer connected to the wireless LAN and you change the EMG3425-Q10As SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the EMG3425-Q10As new settings. Click Network > Wireless LAN 2.4G/5G to open the General screen.

DESCRIPTION Auto Channel Selection Operating Channel Channel Width 802.11 Mode Select a channel from the drop-down list box. The options vary depending on the frequency band and the country you are in. Refer to the Connection Wizard chapter for more information on channels. This option is only available if Auto Channel Selection is disabled. Select this check box for the EMG3425-Q10A to automatically choose the channel with the least interference. Deselect this check box if you wish to manually select the channel using the Channel Selection field. This displays the channel the EMG3425-Q10A is currently using. Select the wireless channel width used by EMG3425-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 EMG3425-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.

A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. Figure 46 LAN Example The LAN screens can help you configure a manage IP address, and partition your physical network into logical networks. 10.2 What You Can Do Use the IP screen to change the IP address for your EMG3425-Q10A (Section 10.4 on page 90). Use the IP Alias screen to have the EMG3425-Q10A apply IP alias to create LAN subnets

(Section 10.5 on page 90). Use the IPv6 LAN screen to configure the IPv6 address for your EMG3425-Q10A on the LAN

(Section 10.6 on page 91). Use the IGMP Snooping screen to enable IGMP Snooping and configure IGMP modes. (Section 10.7 on page 92). EMG3425-Q10A Users Guide 88 Chapter 10 LAN 10.3 What You Need To Know The actual physical connection determines whether the EMG3425-Q10A ports are LAN or WAN ports. There are two separate IP networks, one inside the LAN network and the other outside the WAN network as shown next. Figure 47 LAN and WAN IP Addresses The LAN parameters of the EMG3425-Q10A are preset in the factory with the following values:

IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits) DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.

Reserve Apply Cancel EMG3425-Q10A Users Guide 98 CHAPTER 12 NAT 12.1 Overview NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network. The figure below is a simple illustration of a NAT network. You want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses to the devices (A to D) connected to your EMG3425-Q10A. The ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic coming from A to D going out to the Internet use the IP address of the EMG3425-Q10A, which is 192.168.1.1. Figure 55 NAT Example A: 192.168.1.33 FTP, Telnet, SNMP Ports 21 to 25 B: 192.168.1.34 Port 80 C: 192.168.1.35 LAN WAN 192.168.1.1 IP address assigned by ISP This chapter discusses how to configure NAT on the EMG3425-Q10A. Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the EMG3425-Q10A. 12.1.1 What You Can Do Use the General screen to enable NAT (Section 12.2 on page 101). EMG3425-Q10A Users Guide 99 Chapter 12 NAT Use the Port Forwarding screen to set a default server and change your EMG3425-Q10As port forwarding settings to forward incoming service requests to the server(s) on your local network

(Section 12.3 on page 102). Use the Port Trigger screen to change your EMG3425-Q10As trigger port settings (Section 12.5.3 on page 107). 12.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. Inside/Outside This denotes where a host is located relative to the EMG3425-Q10A, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts. Global/Local This denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side. Note: Inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. An inside local address (ILA) is the IP address of an inside host in a packet when the packet is still in the local network, while an inside global address (IGA) is the IP address of the same inside host when the packet is on the WAN side. The following table summarizes this information. Table 38 NAT Definitions ITEM Inside Outside Local Global DESCRIPTION This refers to the host on the LAN. This refers to the host on the WAN. This refers to the packet address (source or destination) as the packet travels on the LAN. This refers to the packet address (source or destination) as the packet travels on the WAN. Note: NAT never changes the IP address (either local or global) of an outside host. What NAT Does In the simplest form, NAT changes the source IP address in a packet received from a subscriber

(the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed. The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local EMG3425-Q10A Users Guide 100 Chapter 12 NAT network and make them accessible to the outside world. If you do not define any servers, NAT offers the additional benefit of firewall protection. With no servers defined, your EMG3425-Q10A filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT). How NAT Works Each packet has two addresses a source address and a destination address. For outgoing packets, the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address in each packet and then forwards it to the Internet. The EMG3425-Q10A keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this. Figure 56 How NAT Works 12.2 General Use this screen to enable NAT and set a default server. Click Network > NAT to open the General screen. Figure 57 Network > NAT > General EMG3425-Q10A Users Guide 101 Chapter 12 NAT The following table describes the labels in this screen. Table 39 Network > NAT > General LABEL Network Address Translation (NAT) DESCRIPTION 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).

Click Cancel to begin configuring this screen afresh. 12.3 Port Forwarding Screen Use this screen to forward incoming service requests to the server(s) on your local network and set a default server. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded. Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP. Port forwarding allows you to define the local servers to which the incoming services will be forwarded. To change your EMG3425-Q10As port forwarding settings, click Network > NAT >

Name DESCRIPTION This is the rule index number (read-only). Type a unique name (up to 15 characters) for identification purposes. All characters are permitted - including spaces. Incoming is a port (or a range of ports) that a server on the WAN uses when it sends out a particular service. The EMG3425-Q10A forwards the traffic with this port (or range of ports) to the client computer on the LAN that requested the service. Type a port number or the starting port number in a range of port numbers. Type a port number or the ending port number in a range of port numbers. The trigger port is a port (or a range of ports) that causes (or triggers) the EMG3425-

Q10A to record the IP address of the LAN computer that sent the traffic to a server on the WAN. Type a port number or the starting port number in a range of port numbers.

Incoming Port End Port Trigger Port End Port Apply Cancel EMG3425-Q10A Users Guide 105 Chapter 12 NAT 12.5 Technical Reference The following section contains additional technical information about the EMG3425-Q10A features described in this chapter. 12.5.1 NATPort Forwarding: Services and Port Numbers A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Use the Port 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. 12.5.2 NAT Port Forwarding Example Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. Figure 61 Multiple Servers Behind NAT Example EMG3425-Q10A Users Guide 106 Chapter 12 NAT 12.5.3 Trigger Port Forwarding Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service

(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address. Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The EMG3425-Q10A records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the EMG3425-Q10A's WAN port receives a response with a specific port number and protocol

("incoming" port), the EMG3425-Q10A forwards the traffic to the LAN IP address of the computer that sent the request. After that computers connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application. 12.5.4 Trigger Port Forwarding Example The following is an example of trigger port forwarding. Figure 62 Trigger Port Forwarding Process: Example Janes computer Real Audio Server Port 7070 1 2 3 4 Jane requests a file from the Real Audio server (port 7070). Port 7070 is a trigger port and causes the EMG3425-Q10A to record Janes computer IP address. The EMG3425-Q10A associates Jane's computer IP address with the "incoming" port range of 6970-

7170. The Real Audio server responds using a port number ranging between 6970-7170. The EMG3425-Q10A forwards the traffic to Janes computer IP address. 5 Only Jane can connect to the Real Audio server until the connection is closed or times out. The EMG3425-Q10A times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). EMG3425-Q10A Users Guide 107 Chapter 12 NAT 12.5.5 Two Points To Remember About Trigger Ports 1 2 Trigger events only happen on data that is coming from inside the EMG3425-Q10A and going to the outside. If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN cant trigger it. EMG3425-Q10A Users Guide 108 CHAPTER 13 DDNS 13.1 Overview DDNS services let you use a domain name with a dynamic IP address. 13.1.1 What You Need To Know The following terms and concepts may help as you read through this chapter. What is DDNS?

Dynamic Domain Name Service (DDNS) services let you use a fixed domain name with a dynamic IP address. Users can always use the same domain name instead of a different dynamic IP address that changes each time to connect to the EMG3425-Q10A or a server in your network. Note: The EMG3425-Q10A must have a public global IP address and you should have your registered DDNS account information on hand. 13.2 General To change your EMG3425-Q10As DDNS, click Network > DDNS.

EMG3425-Q10A Users Guide 110 CHAPTER 14 Static Route 14.1 Overview This chapter shows you how to configure static routes for your EMG3425-Q10A. The EMG3425-Q10A usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the EMG3425-Q10A send data to devices not reachable through the default gateway, use static routes. For example, the next figure shows a computer (A) connected to the EMG3425-Q10As LAN interface. The EMG3425-Q10A routes most traffic from A to the Internet through the EMG3425-

Q10As 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.

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). Figure 70 Default Firewall Action LAN WAN A 1 2 3 4 16.1.1 What You Can Do Use the General screen to enable or disable the EMG3425-Q10As firewall (Section 16.2 on page 119). 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 16.3 on page 119). 16.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. EMG3425-Q10A Users Guide 117 Chapter 16 Firewall What is a Firewall?

Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot solve every security problem. A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself. Stateful Inspection Firewall Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises. About the EMG3425-Q10A Firewall The EMG3425-Q10As 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 EMG3425-Q10A's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The EMG3425-Q10A can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The EMG3425-Q10A is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN. The EMG3425-Q10A has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet. The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service. Guidelines For Enhancing Security With Your Firewall Change the default password via Web Configurator. Think about access control before you connect to the network in any way, including attaching a modem to the port. 1 2 EMG3425-Q10A Users Guide 118 Chapter 16 Firewall 3 Limit who can access your router. 4 Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5 6 7 For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. Protect against IP spoofing by making sure the firewall is active. Keep the firewall in a secured (locked) room. 16.2 General Screen Use this screen to enable or disable the EMG3425-Q10As firewall, and set up firewall logs.

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

pressroom.php, the EMG3425-Q10A would find tw in the domain name (www.zyxel.com.tw). It would also find news in the file path (news/pressroom.php) but it would not find tw/news. 19.2 Parental Control Screen Use this screen to enable parental control, view the parental control rules and schedules.

See the appendices for information on how to access and use the command interpreter. Domain Name or IP Address URL Checking By default, the EMG3425-Q10A checks the URLs domain name or IP address when performing keyword blocking. This means that the EMG3425-Q10A checks the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, content filtering only searches for keywords within www.zyxel.com.tw. Full Path URL Checking Full path URL checking has the EMG3425-Q10A check the characters that come before the last slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking searches for keywords within www.zyxel.com.tw/news/. Use the ip urlfilter customize actionFlags 6 [disable | enable] command to extend (or not extend) the keyword blocking search to include the URL's full path. EMG3425-Q10A Users Guide 131 Chapter 19 Parental Control File Name URL Checking Filename URL checking has the EMG3425-Q10A check all of the characters in the URL. For example, filename URL checking searches for keywords within the URL www.zyxel.com.tw/

news/pressroom.php. Use the ip urlfilter customize actionFlags 8 [disable | enable] command to extend (or not extend) the keyword blocking search to include the URL's complete filename. EMG3425-Q10A Users Guide 132 CHAPTER 20 Bandwidth Management 20.1 Overview Quality of Service (QoS) refers to both a networks ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-on-

demand. Configure QoS on the EMG3425-Q10A to group and prioritize application traffic and fine-tune network performance. Setting up QoS involves these steps:

1 2 Configure classifiers to sort traffic into different flows. Assign priority and define actions to be performed for a classified traffic flow. The EMG3425-Q10A assigns each packet a priority and then queues the packet accordingly. Packets assigned a high priority are processed more quickly than those with low priority if there is congestion, allowing time-sensitive applications to flow more smoothly. Time-sensitive applications include both those that require a low level of latency (delay) and a low level of jitter (variations in delay) such as Voice over IP (VoIP) or Internet gaming, and those for which jitter alone is a problem such as Internet radio or streaming video. This chapter contains information about configuring QoS and editing classifiers. 20.1.1 What You Can Do in this Chapter The General screen lets you enable or disable QoS and set the upstream bandwidth (Section 20.3 on page 135). The Queue Setup screen lets you configure QoS queue assignment (Section 20.4 on page 136). The Class Setup screen lets you add, edit or delete QoS classifiers (Section 20.5 on page 138). 20.2 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 EMG3425-Q10A Users Guide 133 Chapter 20 Bandwidth Management similar types of traffic together and treating each type as a class. You can use CoS to give different priorities to different packet types. CoS technologies include IEEE 802.1p layer 2 tagging and DiffServ (Differentiated Services or DS). IEEE 802.1p tagging makes use of three bits in the packet header, while DiffServ is a new protocol and defines a new DS field, which replaces the eight-bit ToS (Type of Service) field in the IP header. Tagging and Marking In a QoS class, you can configure whether to add or change the DSCP (DiffServ Code Point) value, IEEE 802.1p priority level and VLAN ID number in a matched packet. When the packet passes through a compatible network, the networking device, such as a backbone switch, can provide specific treatment or service based on the tag or marker. Traffic Shaping Bursty traffic may cause network congestion. Traffic shaping regulates packets to be transmitted with a pre-configured data transmission rate using buffers (or queues). Your EMG3425-Q10A uses the Token Bucket algorithm to allow a certain amount of large bursts while keeping a limit at the average rate. Traffic Rate Traffic Rate c i f f a r T c i f f a r T Time Time

(Before Traffic Shaping)

(After Traffic Shaping) 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. Traffic Rate Traffic Rate c i f f a r T c i f f a r T Time Time

(Before Traffic Policing)

(After Traffic Policing) The EMG3425-Q10A supports three incoming traffic metering algorithms: Token Bucket Filter

(TBF), Single Rate Two Color Maker (srTCM), and Two Rate Two Color Marker (trTCM). You can EMG3425-Q10A Users Guide 134 Chapter 20 Bandwidth Management specify actions which are performed on the colored packets. See Section 20.6 on page 142 for more information on each metering algorithm. 20.3 Bandwidth MGMT General Screen Click Management > Bandwidth MGMT > General to open the screen as shown next. Use this screen to enable or disable QoS and set the upstream bandwidth. See Section 20.1 on page 133 for more information. Figure 78 Management > Bandwidth MGMT > General The following table describes the labels in this screen. Table 56 Management > Bandwidth MGMT > General LABEL QoS State WAN Managed Upstream Bandwidth DESCRIPTION Select the Enable check box to turn on QoS to improve your network performance. Enter the amount of upstream bandwidth for the WAN interfaces that you want to allocate using QoS. The recommendation is to set this speed to match the interfaces actual transmission speed. For example, set the WAN interfaces speed to 100000 kbps if your Internet connection has an upstream transmission speed of 100 Mbps. You can set this number higher than the interfaces actual transmission speed. The EMG3425-Q10A uses up to 95% of the DSL ports actual upstream transmission speed even if you set this number higher than the DSL ports actual transmission speed. You can also set this number lower than the interfaces actual transmission speed. This will cause the EMG3425-Q10A to not use some of the interfaces available bandwidth. If you leave this field blank, the EMG3425-Q10A automatically sets this number to be 95%

of the WAN interfaces actual upstream transmission speed. EMG3425-Q10A Users Guide 135 Chapter 20 Bandwidth Management Table 56 Management > Bandwidth MGMT > General (continued) (continued) LABEL LAN Managed Downstream Bandwidth DESCRIPTION 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 EMG3425-Q10A to not use some of the interfaces available bandwidth. If you leave this field blank, the EMG3425-Q10A automatically sets this to the LAN interfaces maximum supported connection speed. Click Apply to save your changes.

Queues with larger weights get more bandwidth than queues with smaller weights. This field displays Drop Tail (DT). Drop Tail (DT) is a simple queue management algorithm that allows the EMG3425-Q10A buffer to accept as many packets as it can until it is full. Once the buffer is full, new packets that arrive are dropped until there is space in the buffer again (packets are transmitted out of it).

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

IEEE 802.1Q Tag The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to process the frame across the network. IEEE 802.1p specifies the user priority field and defines up to eight separate traffic types. The following table describes the traffic types defined in the IEEE 802.1d standard (which incorporates the 802.1p). Table 61 IEEE 802.1p Priority Level and Traffic Type PRIORITY LEVEL Level 7 Level 6 TRAFFIC TYPE Typically used for network control traffic such as router configuration messages. Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay). Typically used for video that consumes high bandwidth and is sensitive to jitter. Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network Architecture) transactions. Typically used for excellent effort or better than best effort and would include important business traffic that can tolerate some delay. This is for spare bandwidth. Level 5 Level 4 Level 3 Level 2 EMG3425-Q10A Users Guide 142 Chapter 20 Bandwidth Management Table 61 IEEE 802.1p Priority Level and Traffic Type PRIORITY LEVEL Level 1 TRAFFIC TYPE 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. Typically used for best-effort traffic. Level 0 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. DSCP (6 bits) Unused (2 bits) The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different kinds of forwarding. Resources can then be allocated according to the DSCP values and the configured policies. IP Precedence Similar to IEEE 802.1p prioritization at layer-2, you can use IP precedence to prioritize packets in a layer-3 network. IP precedence uses three bits of the eight-bit ToS (Type of Service) field in the IP header. There are eight classes of services (ranging from zero to seven) in IP precedence. Zero is the lowest priority level and seven is the highest. Automatic Priority Queue Assignment If you enable QoS on the EMG3425-Q10A, the EMG3425-Q10A can automatically base on the IEEE 802.1p priority level, IP precedence and/or packet length to assign priority to traffic which does not match a class. EMG3425-Q10A Users Guide 143 Chapter 20 Bandwidth Management The following table shows you the internal layer-2 and layer-3 QoS mapping on the EMG3425-

Q10A. On the EMG3425-Q10A, traffic assigned to higher priority queues gets through faster while traffic in lower index queues is dropped if the network is congested. Table 62 Internal Layer2 and Layer3 QoS Mapping PRIORITY QUEUE 0 1 2 3 4 5 6 7 LAYER 2 IEEE 802.1P USER PRIORITY

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. EMG3425-Q10A Users Guide 144 Chapter 20 Bandwidth Management If there are no tokens in the bucket, the EMG3425-Q10A stops transmitting until enough tokens are generated. If not enough tokens are available, the EMG3425-Q10A treats the packet in either one of the following ways:

In traffic shaping:

Holds it in the queue until enough tokens are available in the bucket. In traffic policing:

Drops it. Transmits it but adds a DSCP mark. The EMG3425-Q10A may drop these marked packets if the network is overloaded. Configure the bucket size to be equal to or less than the amount of the bandwidth that the interface can support. It does not help if you set it to a bucket size over the interfaces capability. The smaller the bucket size, the lower the data transmission rate and that may cause outgoing packets to be dropped. A larger transmission rate requires a big bucket size. For example, use a bucket size of 10 kbytes to get the transmission rate up to 10 Mbps. Single Rate Three Color Marker The Single Rate Three Color Marker (srTCM, defined in RFC 2697) is a type of traffic policing that identifies packets by comparing them to one user-defined rate, the Committed Information Rate

(CIR), and two burst sizes: the Committed Burst Size (CBS) and Excess Burst Size (EBS). The srTCM evaluates incoming packets and marks them with one of three colors which refer to packet loss priority levels. High packet loss priority level is referred to as red, medium is referred to as yellow and low is referred to as green. The srTCM is based on the token bucket filter and has two token buckets (CBS and EBS). Tokens are generated and added into the bucket at a constant rate, called Committed Information Rate

(CIR). When the first bucket (CBS) is full, new tokens overflow into the second bucket (EBS). All packets are evaluated against the CBS. If a packet does not exceed the CBS it is marked green. Otherwise it is evaluated against the EBS. If it is below the EBS then it is marked yellow. If it exceeds the EBS then it is marked red. The following shows how tokens work with incoming packets in srTCM:

A packet arrives. The packet is marked green and can be transmitted if the number of tokens in the CBS bucket is equal to or greater than the size of the packet (in bytes). After a packet is transmitted, a number of tokens corresponding to the packet size is removed from the CBS bucket. If there are not enough tokens in the CBS bucket, the EMG3425-Q10A checks the EBS bucket. The packet is marked yellow if there are sufficient tokens in the EBS bucket. Otherwise, the packet is marked red. No tokens are removed if the packet is dropped. Two Rate Three Color Marker The Two Rate Three Color Marker (trTCM, defined in RFC 2698) is a type of traffic policing that identifies packets by comparing them to two user-defined rates: the Committed Information Rate

(CIR) and the Peak Information Rate (PIR). The CIR specifies the average rate at which packets are admitted to the network. The PIR is greater than or equal to the CIR. CIR and PIR values are based EMG3425-Q10A Users Guide 145 Chapter 20 Bandwidth Management on the guaranteed and maximum bandwidth respectively as negotiated between a service provider and client. The trTCM evaluates incoming packets and marks them with one of three colors which refer to packet loss priority levels. High packet loss priority level is referred to as red, medium is referred to as yellow and low is referred to as green. The trTCM is based on the token bucket filter and has two token buckets (Committed Burst Size

(CBS) and Peak Burst Size (PBS)). Tokens are generated and added into the two buckets at the CIR and PIR respectively. All packets are evaluated against the PIR. If a packet exceeds the PIR it is marked red. Otherwise it is evaluated against the CIR. If it exceeds the CIR then it is marked yellow. Finally, if it is below the CIR then it is marked green. The following shows how tokens work with incoming packets in trTCM:

A packet arrives. If the number of tokens in the PBS bucket is less than the size of the packet (in bytes), the packet is marked red and may be dropped regardless of the CBS bucket. No tokens are removed if the packet is dropped. If the PBS bucket has enough tokens, the EMG3425-Q10A checks the CBS bucket. The packet is marked green and can be transmitted if the number of tokens in the CBS bucket is equal to or greater than the size of the packet (in bytes). Otherwise, the packet is marked yellow. EMG3425-Q10A Users Guide 146 CHAPTER 21 Remote Management 21.1 Overview This chapter provides information on the Remote Management screens. Remote Management allows you to manage your EMG3425-Q10A from a remote location through the following interfaces:

LAN and WAN LAN only WAN only Note: The EMG3425-Q10A is managed using the Web Configurator. 21.2 What You Can Do in this Chapter Use the WWW screen to define the interface/s from which the EMG3425-Q10A can be managed remotely using the web and specify a secure client that can manage the EMG3425-Q10A (Section 21.4 on page 148). Use the Telnet screen to define the interface/s from which the EMG3425-Q10A can be managed remotely using Telnet service and specify a secure client that can manage the EMG3425-Q10A

(Section 21.5 on page 151). Your EMG3425-Q10A can act as an SNMP agent, which allows a manager station to manage and monitor the EMG3425-Q10A through the network. Use the SNMP screen to configure SNMP settings. You can also specify from which IP addresses the access can come (Section 21.6 on page 152). Use the Wake On LAN screen to enable Wake on LAN and remotely turn on a device on the local network (Section 21.7 on page 154).

Your EMG3425-Q10A supports SNMP agent functionality, which allows a manager station to manage and monitor the EMG3425-Q10A through the network. The EMG3425-

Q10A supports SNMP version one (SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation. Figure 85 SNMP Management Model An SNMP managed network consists of two main types of component: agents and a manager. An agent is a management software module that resides in a managed device (the EMG3425-

Q10A). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. EMG3425-Q10A Users Guide 152 Chapter 21 Remote Management The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects. SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:

Get - Allows the manager to retrieve an object variable from the agent. GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. Set - Allows the manager to set values for object variables within an agent. Trap - Used by the agent to inform the manager of some events. To change your EMG3425-Q10As SNMP settings, click Configuration > Management > Remote MGMT > SNMP to display the screen as shown. Figure 86 Configuration > Management > Remote MGMT > SNMP The following table describes the labels in this screen. Table 65 Configuration > Management > Remote MGMT > SNMP LABEL SNMP Settings Server Port DESCRIPTION The SNMP agent listens on port 161 by default. If you change the SNMP server port to a different number on the EMG3425-Q10A, for example 8161, then you must notify people who need to access the EMG3425-Q10A SNMP agent to use the same port.

EMG3425-Q10A Users Guide 157 CHAPTER 22 Universal Plug-and-Play (UPnP) 22.1 Overview This chapter introduces the UPnP feature in the web configurator. Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use. 22.2 What You Need to Know UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. 22.2.1 NAT Traversal UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:

Dynamic port mapping Learning public IP addresses Assigning lease times to mappings Windows Messenger is an example of an application that supports NAT traversal and UPnP. See the NAT chapter for more information on NAT. 22.2.2 Cautions with UPnP The automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the EMG3425-Q10A allows multicast messages on the LAN only. EMG3425-Q10A Users Guide 158 Chapter 22 Universal Plug-and-Play (UPnP) All UPnP-enabled devices may communicate freely with each other without additional configuration.

Use the SAMBA screen to enable file-sharing via the EMG3425-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 167). Use the FTP screen to allow file sharing via the EMG3425-Q10A using FTP and create user accounts (Section 23.7 on page 169). 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 EMG3425-Q10A can function as a DLNA-compliant media server and stream files to DLNA-compliant media clients without any configuration. EMG3425-Q10A Users Guide 165 Chapter 23 USB Media Sharing Workgroup name This is the name given to a set of computers that are connected on a network and share resources such as a printer or files. Windows automatically assigns the workgroup name when you set up a network. File Systems A file system is a way of storing and organizing files on your hard drive and storage device. Often different operating systems such as Windows or Linux have different file systems. The file-sharing feature on your EMG3425-Q10A supports New Technology File System (NTFS), File Allocation Table

(FAT) and FAT32 file systems. Windows/CIFS Common Internet File System (CIFS) is a standard protocol supported by most operating systems in order to share files across the network. CIFS runs over TCP/IP but uses the SMB (Server Message Block) protocol found in Microsoft Windows for file and printer access; therefore, CIFS will allow all applications, not just Web browsers, to open and share files across the Internet. The EMG3425-Q10A uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS compatible computers can access the USB file storage devices connected to the EMG3425-Q10A. CIFS protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to your systems specifications for CIFS compatibility). Samba SMB is a client-server protocol used by Microsoft Windows systems for sharing files, printers, and so on. Samba is a free SMB server that runs on most Unix and Unix-like systems. It provides an implementation of an SMB client and server for use with non-Microsoft operating systems. File Transfer Protocol This is a method of transferring data from one computer to another over a network such as the Internet. 23.4 Before You Begin 1 2 Make sure the EMG3425-Q10A is connected to your network and turned on. Connect the USB device to one of the EMG3425-Q10As USB ports. The EMG3425-Q10A detects the USB device and makes its contents available for browsing.

EMG3425-Q10A Users Guide 191 Chapter 26 Troubleshooting 6 Make sure traffic between the WLAN and the LAN is not blocked by the firewall on the EMG3425-

Q10A. 7 Make sure you allow the EMG3425-Q10A to be remotely accessed through the WLAN interface. Check your remote management settings. See the chapter on Wireless LAN in the Users Guide for more information. I set up URL keyword blocking, but I can still access a website that should be blocked. Make sure that you enable parental control in the Parental Control screen, set up rules and turn on the rules. Make sure that the keywords that you type are listed in the rules Keyword List. If a keyword that is listed in the Keyword List is not blocked when it is found in a URL, customize the keyword blocking using commands. See the Customizing Keyword Blocking URL Checking section in the IPv6 Firewall chapter. I cannot access the Web Configurator after I switched to AP mode. When you change from router mode to AP mode, your computer must have an IP address in the range between 192.168.1.3 and 192.168.1.254. Refer to Appendix B on page 203 for instructions on how to change your computers 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. EMG3425-Q10A Users Guide 192 Chapter 26 Troubleshooting 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. 26.7 USB Device Problems I cannot access or see a USB device that is connected to the EMG3425-Q10A. 1 Disconnect the problematic USB device, then reconnect it to the EMG3425-Q10A. 2 3 4 5 6 Ensure that the USB device has power. Check your cable connections. Restart the EMG3425-Q10A by disconnecting the power and then reconnecting it. If the USB device requires a special driver, install the driver from the installation disc that came with the device. After driver installation, reconnect the USB device to the EMG3425-Q10A and try to connect to it again with your computer. If the problem persists, contact your vendor. What kind of USB devices do the EMG3425-Q10A support?
