Chapter 1 IntroductionEMG3425-Q10A User’s Guide141.4 Good Habits for Managing the EMG3425-Q10ADo the following things regularly to make the EMG3425-Q10A more secure and to manage the EMG3425-Q10A more effectively.• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.• Write down the password and put it in a safe place.• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the EMG3425-Q10A to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the EMG3425-Q10A. You could simply restore your last configuration.1.5 Resetting the EMG3425-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 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 Button1Make sure the power LED is on.2Press the RESET button for one to four seconds to restart/reboot the EMG3425-Q10A.3Press the RESET button for longer than five seconds to set the EMG3425-Q10A back to its factory-default configurations.1.6 The WPS ButtonYour EMG3425-Q10A supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance.WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each device’s documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) on each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves.
Chapter 1 IntroductionEMG3425-Q10A User’s Guide15You can use the WPS button ( ) on the front panel of the EMG3425-Q10A to activate WPS in order to quickly set up a wireless network with strong security.1Make sure the power LED is on (not blinking).2Press the WPS button for more than three seconds and release it. Press the WPS button on another WPS-enabled device within range of the EMG3425-Q10A. Note: You must activate WPS on the EMG3425-Q10A and on another wireless device within two minutes of each other. For more information on using WPS, see Section 6.2 on page 38.1.7 LEDsLook at the LED lights on the front panel to determine the status of the EMG3425-Q10A. Use the LED button on the rear panel of the device to turn the LED lights on or off. If you have already pushed the LED button to the ON position but none of the LEDS are on, make sure the EMG3425-Q10A is receiving power and the power is turned on.Note: The Pow e r LED will be on even if you push the LED button to the OFF position. This is for you to determine whether the EMG3425-Q10A is powered on.Figure 2 LED ButtonLED button

This example uses the EMG3425-Q10A as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card).There are two WPS methods for creating a secure connection via the web configurator or utility. This tutorial shows you how to do both.•Push But t on Configurat ion ( PBC) - create a secure wireless network simply by pressing a button. See Section 6.2.1 on page 38. This is the easier method.•PI N Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the EMG3425-Q10A’s interface. See Section 6.2.2 on page 39. This is the more secure method, since one device can authenticate the other.6.2.1 Push Button Configuration (PBC)1Make sure that your EMG3425-Q10A is turned on. Make sure the W I FI button (at the back panel of the EMG3425-Q10A) is pushed in, and that the device is placed within range of your notebook. 2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and utility in your notebook.3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (St a r t or W PS button)4Log into EMG3425-Q10A’s Web Configurator and press the Pu sh But t on in the Configuration > N e tw ork > W ir ele ss LAN 2 .4 G > W PS St a t ion screen.
Chapter 6 TutorialsEMG3425-Q10A User’s Guide39Note: Your EMG3425-Q10A has a WPS button located on its panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other.Note: It doesn’t matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The EMG3425-Q10A sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the EMG3425-Q10A securely.

EMG3425-Q10A User’s Guide57CHAPTER 8WAN8.1 OverviewThis chapter discusses the EMG3425-Q10A’s W AN screens. Use these screens to configure your EMG3425-Q10A for Internet access.A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations.Figure 25 LAN and WAN8.2 What You Can Do•Use the I nt er n e t Connection screen to enter your ISP information and set how the computer acquires its IP, DNS and WAN MAC addresses (Section 8.4 on page 59).8.3 What You Need To KnowThe 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 ConnectionEncapsulation MethodEncapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
Chapter 8 WANEMG3425-Q10A User’s Guide58over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password (and service name) for user authentication.WAN IP AddressThe 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 AssignmentUse Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The EMG3425-Q10A can get the DNS server addresses in the following ways.1The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.2If your ISP dynamically assigns the DNS server IP addresses (along with the EMG3425-Q10A’s WAN IP address), set the DNS server fields to get the DNS server address from the ISP. WAN MAC AddressThe MAC address screen allows users to configure the WAN port's MAC address by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Fa ctory Default to select the factory assigned default MAC Address.Otherwise, click Clone t he com pute r 's M AC addr e ss - I P Address and enter the IP address of the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port.
Chapter 8 WANEMG3425-Q10A User’s Guide59MulticastTraditionally, 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 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 EMG3425-Q10A supports both IGMP version 1 (I GMP- v 1 ) and IGMP version 2 (I GM P- v2 ). At start up, the EMG3425-Q10A queries all directly connected networks to gather group membership. After that, the EMG3425-Q10A periodically updates this information. IP multicasting can be enabled/disabled on the EMG3425-Q10A WAN interface in the Web Configurator (W AN ). Select N one to disable IP multicasting on these interfaces.8.4 Management WANUse this screen to view, change, or add your EMG3425-Q10A’s Internet access settings.

Chapter 8 WANEMG3425-Q10A User’s Guide64(DSL, cable, wireless, etc.) connection. The PPP over Et h e r net option is for a dial-up connection using PPPoE.For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius).One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals.Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site.By implementing PPPoE directly on the EMG3425-Q10A (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the EEMG3425-Q10A does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.This screen displays when you select PPPoE encapsulation.

EMG3425-Q10A User’s Guide68CHAPTER 9Wireless LAN9.1 OverviewThis chapter discusses how to configure the wireless network settings in your EMG3425-Q10A. The EMG3425-Q10A is able to function both 2.4GHz and 5GHz network at the same time. You can have different wireless and wireless security settings for 2.4GHz and 5GHz wireless LANs. Click Configura t ion > Ne t w ork > W ir e less LAN 2 .4 G or W ireless LAN 5 G to configure to do so.See the appendices for more detailed information about wireless networks.The following figure provides an example of a wireless network.Figure 30 Example of a Wireless 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 EMG3425-Q10A is the AP.
Chapter 9 Wireless LANEMG3425-Q10A User’s Guide699.1.1 What You Can Do•Use the Ge n e r a l screen to turn the wireless connection on or off, set up wireless security between the EMG3425-Q10A and the wireless clients, and make other basic configuration changes (Section 9.2 on page 73).•Use the More AP screen to set up multiple wireless networks on your EMG3425-Q10A (Section 9.4 on page 79). •Use the MAC Filte r screen to allow or deny wireless stations based on their MAC addresses from connecting to the EMG3425-Q10A (Section 9.5 on page 81).•Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 9.6 on page 83).•Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 9.7 on page 83).•Use the W PS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 9.8 on page 84).•Use the W PS St at ion screen to add a wireless station using WPS (Section 9.9 on page 86). •Use the Schedu ling screen to set the times your wireless LAN is turned on and off (Section 9.10 on page 86).9.1.2 What You Should 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 LANEMG3425-Q10A User’s Guide70MAC 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.EncryptionWireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses.2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 9 Wireless LANEMG3425-Q10A User’s Guide71The types of encryption you can choose depend on the type of user authentication. (See page 70 for information about this.)For example, if the wireless network has a RADIUS server, you can choose W PA or W PA2 . If users do not log in to the wireless network, you can choose no encryption, St at ic W EP, W PA- PSK, or W PA2 - PSK.Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up St a t ic W EP in the wireless network.Note: It is recommended that wireless networks use W PA- PSK, W PA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly.Note: It is not possible to use W PA- PSK, W PA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database.When you select W PA2 or W PA2 - PSK in your EMG3425-Q10A, you can also select an option (W PA/W PA- PSK Com pat ible) to support WPA/WPA-PSK as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up W PA2 - PSK or W PA2 (depending on the type of wireless network login) and select the W PA/W PA- PSK Com pa t ible option in the EMG3425-Q10A.Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key.Guest WLANGuest 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.Table 18 Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERW eakest No Security WPAStatic WEPWPA-PSKSt r on ge st WPA2-PSK WPA2
Chapter 9 Wireless LANEMG3425-Q10A User’s Guide72Figure 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 NetworksWPSWiFi 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 NAZ600 kbps100 kbps300 kbpsNA
Chapter 9 Wireless LANEMG3425-Q10A User’s Guide73Number) 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-Q10A’s 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-Q10A’s new settings.Click N e t w o rk > W ir e less LAN 2 .4 G/ 5 G to open the Ge n e r al screen.Figure 33 Network > Wireless LAN 2.4G/5G > General The following table describes the general wireless LAN labels in this screen.Table 19 Network > Wireless LAN 2.4G/5G > GeneralLABEL DESCRIPTIONWireless LAN Select Enable to activate the 2.4GHz and/or 5GHz wireless LAN.

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 Channe l Selection is disabled.Auto Channel SelectionSelect 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 Channe l Se lection field.Operating Channel This displays the channel the EMG3425-Q10A is currently using.Channel Width 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 Aut o 2 0 / 4 0 MHz or Aut o 2 0 / 4 0 / 8 0 MHz to allow the EMG3425-Q10A to adjust the channel bandwidth automatically.4 0 M H z (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. A 8 0 M H z channel consists of two adjacent 40 MHz channels. The wireless clients must also support 4 0 M H z or 8 0 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. Select 2 0 M H z if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding.802.11 Mode If you are in the W ire le ss LAN 2 .4 G > Gener a l screen, you can select from the following:•8 0 2 .1 1 b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the EMG3425-Q10A.

EMG3425-Q10A User’s Guide99CHAPTER 12NAT12.1 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 ExampleThis chapter discusses how to configure NAT on the EMG3425-Q10A.Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the EMG3425-Q10A.12.1.1 What You Can Do•Use the Ge n e r a l screen to enable NAT (Section 12.2 on page 101).A: 192.168.1.33B: 192.168.1.34C: 192.168.1.35IP address 192.168.1.1WANLANassigned by ISPFTP, Telnet, SNMPPort 80Ports 21 to 25

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 Table 38 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 12 NATEMG3425-Q10A User’s Guide101network and make them accessible to the outside world. If you do not define any servers, NAT offers the additional benefit of firewall protection. With no servers defined, your EMG3425-Q10A filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The I P Network Address Translator ( NAT).How NAT 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 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 Works12.2 GeneralUse this screen to enable NAT and set a default server. Click Ne t w ork > N AT to open the Gener a l screen.Figure 57 Network > NAT > General
Chapter 12 NATEMG3425-Q10A User’s Guide102The following table describes the labels in this screen.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.

Chapter 12 NATEMG3425-Q10A User’s Guide10612.5 Technical ReferenceThe following section contains additional technical information about the EMG3425-Q10A features described in this chapter.12.5.1 NATPort Forwarding: Services and Port NumbersA port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Use the Port Forw a rding screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers.In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP.12.5.2 NAT Port Forwarding ExampleLet's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet.Figure 61 Multiple Servers Behind NAT Example
Chapter 12 NATEMG3425-Q10A User’s Guide10712.5.3 Trigger Port Forwarding Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address. Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The EMG3425-Q10A records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the EMG3425-Q10A's WAN port receives a response with a specific port number and protocol ("incoming" port), the EMG3425-Q10A forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.12.5.4 Trigger Port Forwarding Example The following is an example of trigger port forwarding.Figure 62 Trigger Port Forwarding Process: Example1Jane requests a file from the Real Audio server (port 7070).2Port 7070 is a “trigger” port and causes the EMG3425-Q10A to record Jane’s computer IP address. The EMG3425-Q10A associates Jane's computer IP address with the "incoming" port range of 6970-7170.3The Real Audio server responds using a port number ranging between 6970-7170.4The EMG3425-Q10A forwards the traffic to Jane’s computer IP address. 5Only Jane can connect to the Real Audio server until the connection is closed or times out. The EMG3425-Q10A times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). Jane’s com puterRea l Audio ServerPort 7 0 7 0

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 Action16.1.1 What You Can Do•Use the Ge n e r a l screen to enable or disable the EMG3425-Q10A’s firewall (Section 16.2 on page 119).•Use the Service s 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 KnowThe following terms and concepts may help as you read through this chapter.WANLAN3412A
Chapter 16 FirewallEMG3425-Q10A User’s Guide118What 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 FirewallThe EMG3425-Q10A’s firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks.It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (click the General tab under Fir e w all and then click the Enable Fir e w a ll check box). The EMG3425-Q10A's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The EMG3425-Q10A can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The EMG3425-Q10A is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.The EMG3425-Q10A has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet.The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service.Guidelines For Enhancing Security With Your 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.
Chapter 16 FirewallEMG3425-Q10A User’s Guide1193Limit who can access your router. 4Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. 6Protect against IP spoofing by making sure the firewall is active. 7Keep the firewall in a secured (locked) room. 16.2 General Screen Use this screen to enable or disable the EMG3425-Q10A’s firewall, and set up firewall logs.

EMG3425-Q10A User’s Guide127CHAPTER 19Parental Control19.1 OverviewParental controls allow you to block specific URLs. You can also define time periods and days during which the EMG3425-Q10A performs parental control on a specific user. 19.1.1 What You Need To KnowThe following terms and concepts may help as you read through this chapter.Keyword Blocking URL CheckingThe EMG3425-Q10A checks the URL’s domain name (or IP address) and file path separately when performing keyword blocking. The URL’s domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is www.zyxel.com.tw.The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.Since the EMG3425-Q10A checks the URL’s domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the EMG3425-Q10A would find “tw” in the domain name (www.zyxel.com.tw). It would also find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.19.2 Parental Control ScreenUse this screen to enable parental control, view the parental control rules and schedules.Click Configu r at ion > Se curit y > Pa rent a l Cont r ol to open the following screen.

EMG3425-Q10A User’s Guide133CHAPTER 20Bandwidth Management20.1 Overview Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-on-demand.Configure QoS on the EMG3425-Q10A to group and prioritize application traffic and fine-tune network performance. Setting up QoS involves these steps:1Configure classifiers to sort traffic into different flows. 2Assign priority and define actions to be performed for a classified traffic flow. The EMG3425-Q10A assigns each packet a priority and then queues the packet accordingly. Packets assigned a high priority are processed more quickly than those with low priority if there is congestion, allowing time-sensitive applications to flow more smoothly. Time-sensitive applications include both those that require a low level of latency (delay) and a low level of jitter (variations in delay) such as Voice over IP (VoIP) or Internet gaming, and those for which jitter alone is a problem such as Internet radio or streaming video.This chapter contains information about configuring QoS and editing classifiers.20.1.1 What You Can Do in this Chapter•The Ge nera l screen lets you enable or disable QoS and set the upstream bandwidth (Section 20.3 on page 135).•The Queue Se t up screen lets you configure QoS queue assignment (Section 20.4 on page 136).•The Cla ss Se t u p screen lets you add, edit or delete QoS classifiers (Section 20.5 on page 138).20.2 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
Chapter 20 Bandwidth ManagementEMG3425-Q10A User’s Guide134similar 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 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 EMG3425-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 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).

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 EMG3425-Q10A uses up to 95% of the DSL port’s actual upstream transmission speed even if you set this number higher than the DSL port’s actual transmission speed.You can also set this number lower than the interfaces’ actual transmission speed. This will cause the EMG3425-Q10A to not use some of the interfaces’ available bandwidth.If you leave this field blank, the EMG3425-Q10A automatically sets this number to be 95% of the WAN interfaces’ actual upstream transmission speed.

Chapter 20 Bandwidth ManagementEMG3425-Q10A User’s Guide14220.6 Technical ReferenceThe following section contains additional technical information about the EMG3425-Q10A features described in this chapter.IEEE 802.1Q TagThe IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to process the frame across the network. IEEE 802.1p specifies the user priority field and defines up to eight separate traffic types. The following table describes the traffic types defined in the IEEE 802.1d standard (which incorporates the 802.1p). VLAN ID If you select Rem ark , enter a VLAN ID number with which the EMG3425-Q10A replaces the VLAN ID of the frames.If you select Rem ove, the EMG3425-Q10A deletes the VLAN ID of the frames before forwarding them out.If you select Add, the EMG3425-Q10A treat all matched traffic untagged and add a second VLAN ID.If you select Uncha nge, the EMG3425-Q10A keep the VLAN ID in the packets.Step 4: Outgoing queue selectionTo Queue Index Select a queue that applies to this class.You should have configured a queue in the Queue Se t up screen already.Back Click this to return to the previous screen.Apply Click this to save your changes.Cancel Click this to exit this screen without saving.Table 60 Management > Bandwidth MGMT > Class Setup: Add/Edit new classLABEL DESCRIPTIONTable 61 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”.
Chapter 20 Bandwidth ManagementEMG3425-Q10A User’s Guide143DiffServ 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 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 AssignmentIf you enable QoS on the EMG3425-Q10A, the EMG3425-Q10A can automatically base on the IEEE 802.1p priority level, IP precedence and/or packet length to assign priority to traffic which does not match a class. Level 1 This is typically used for non-critical “background” traffic such as bulk transfers that are allowed but that should not affect other applications and users. Level 0 Typically used for best-effort traffic.DSCP (6 bits) Unused (2 bits)Table 61 IEEE 802.1p Priority Level and Traffic TypePRIORITY LEVEL TRAFFIC TYPE
Chapter 20 Bandwidth ManagementEMG3425-Q10A User’s Guide144The following table shows you the internal layer-2 and layer-3 QoS mapping on the EMG3425-Q10A. On the EMG3425-Q10A, traffic assigned to higher priority queues gets through faster while traffic in lower index queues is dropped if the network is congested.Token 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.

Chapter 20 Bandwidth ManagementEMG3425-Q10A User’s Guide145• If there are no tokens in the bucket, the EMG3425-Q10A stops transmitting until enough tokens are generated. • If not enough tokens are available, the EMG3425-Q10A treats the packet in either one of the following ways:In traffic shaping:• Holds it in the queue until enough tokens are available in the bucket.In traffic policing:•Drops it.• Transmits it but adds a DSCP mark. The EMG3425-Q10A may drop these marked packets if the network is overloaded.Configure the bucket size to be equal to or less than the amount of the bandwidth that the interface can support. It does not help if you set it to a bucket size over the interface’s capability. The smaller the bucket size, the lower the data transmission rate and that may cause outgoing packets to be dropped. A larger transmission rate requires a big bucket size. For example, use a bucket size of 10 kbytes to get the transmission rate up to 10 Mbps.Single Rate Three Color Marker The Single Rate Three Color Marker (srTCM, defined in RFC 2697) is a type of traffic policing that identifies packets by comparing them to one user-defined rate, the Committed Information Rate (CIR), and two burst sizes: the Committed Burst Size (CBS) and Excess Burst Size (EBS).The srTCM evaluates incoming packets and marks them with one of three colors which refer to packet loss priority levels. High packet loss priority level is referred to as red, medium is referred to as yellow and low is referred to as green. The srTCM is based on the token bucket filter and has two token buckets (CBS and EBS). Tokens are generated and added into the bucket at a constant rate, called Committed Information Rate (CIR). When the first bucket (CBS) is full, new tokens overflow into the second bucket (EBS).All packets are evaluated against the CBS. If a packet does not exceed the CBS it is marked green. Otherwise it is evaluated against the EBS. If it is below the EBS then it is marked yellow. If it exceeds the EBS then it is marked red.The following shows how tokens work with incoming packets in srTCM:• A packet arrives. The packet is marked green and can be transmitted if the number of tokens in the CBS bucket is equal to or greater than the size of the packet (in bytes).• After a packet is transmitted, a number of tokens corresponding to the packet size is removed from the CBS bucket. • If there are not enough tokens in the CBS bucket, the EMG3425-Q10A checks the EBS bucket. The packet is marked yellow if there are sufficient tokens in the EBS bucket. Otherwise, the packet is marked red. No tokens are removed if the packet is dropped.Two Rate Three Color Marker The Two Rate Three Color Marker (trTCM, defined in RFC 2698) is a type of traffic policing that identifies packets by comparing them to two user-defined rates: the Committed Information Rate (CIR) and the Peak Information Rate (PIR). The CIR specifies the average rate at which packets are admitted to the network. The PIR is greater than or equal to the CIR. CIR and PIR values are based
Chapter 20 Bandwidth ManagementEMG3425-Q10A User’s Guide146on the guaranteed and maximum bandwidth respectively as negotiated between a service provider and client.The trTCM evaluates incoming packets and marks them with one of three colors which refer to packet loss priority levels. High packet loss priority level is referred to as red, medium is referred to as yellow and low is referred to as green. The trTCM is based on the token bucket filter and has two token buckets (Committed Burst Size (CBS) and Peak Burst Size (PBS)). Tokens are generated and added into the two buckets at the CIR and PIR respectively. All packets are evaluated against the PIR. If a packet exceeds the PIR it is marked red. Otherwise it is evaluated against the CIR. If it exceeds the CIR then it is marked yellow. Finally, if it is below the CIR then it is marked green.The following shows how tokens work with incoming packets in trTCM:• A packet arrives. If the number of tokens in the PBS bucket is less than the size of the packet (in bytes), the packet is marked red and may be dropped regardless of the CBS bucket. No tokens are removed if the packet is dropped.• If the PBS bucket has enough tokens, the EMG3425-Q10A checks the CBS bucket. The packet is marked green and can be transmitted if the number of tokens in the CBS bucket is equal to or greater than the size of the packet (in bytes). Otherwise, the packet is marked yellow.

Chapter 21 Remote ManagementEMG3425-Q10A User’s Guide15221.6 SNMP ScreenSimple Network Management Protocol is a protocol used for exchanging management information between network devices. Your EMG3425-Q10A supports SNMP agent functionality, which allows a manager station to manage and monitor the EMG3425-Q10A through the network. The EMG3425-Q10A supports SNMP version one (SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation.Figure 85 SNMP Management ModelAn 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. Trust DomainThis is available only when you select Trust Dom ain in the Se cured Client I P Address field.#This displays the index number of the trust domain.IP Address/Domain This field displays the IP address/domain.Modify Click the Ed it icon to go to the screen where you can edit the IP address/domain.Click the D e let e icon to delete an existing IP address/domain.Apply Click Apply to save your customized settings. Cancel Click Cancel to begin configuring this screen afresh.Table 64 Configuration > Management > Remote MGMT > Telnet (continued)LABEL DESCRIPTION
Chapter 21 Remote ManagementEMG3425-Q10A User’s Guide153The 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-Q10A’s SNMP settings, click Con figura t ion > Ma nagem e nt > Rem ote MGMT > SN M P to display the screen as shown.Figure 86 Configuration > Management > Remote MGMT > SNMP The following table describes the labels in this screen.

EMG3425-Q10A User’s Guide158CHAPTER 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. When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the EMG3425-Q10A allows multicast messages on the LAN only.

Chapter 23 USB Media SharingEMG3425-Q10A User’s Guide166Workgroup 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 EMG3425-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 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). 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. 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 BeginMake sure the EMG3425-Q10A is connected to your network and turned on.1Connect the USB device to one of the EMG3425-Q10A’s USB ports. 2The EMG3425-Q10A detects the USB device and makes its contents available for browsing.
