CHAPTER 1 Introduction 1.1 Overview This chapter introduces the main features and applications of the NBG6716. The NBG6716 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 NBG6716 also supports the new StreamBoost technology, which is smart Quality of Service (QoS), to redistribute traffic over the NBG6716 for the best possible performance in a home network. There are two USB 2.0 ports on the side panel of your NBG6716. You can connect USB (version 2.0 or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6716 automatically detects the USB devices. Two USB eject buttons are located above the USB ports. Push the eject button of the corresponding USB port for 2 seconds. Make sure the USB LED is off before removing your USB device. This will remove your USB device safely, preventing file or data loss if it is being transmitted through the USB device. Figure 1 USB Ports and Eject Buttons Eject buttons USB ports Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB storage devices (such as memory sticks, USB hard drives) and/or USB devices

(such as USB printers). Other USB products are not guaranteed to function properly with the NBG6716. NBG6716 Users Guide 13 Chapter 1 Introduction 1.1.1 Dual-Band The NBG6716 is a dual-band AP and able to function both 2.4G and 5G networks at the same time.

compatible device. WAN. Connect to a broadband modem/router for Internet access. 1.3 Ways to Manage the NBG6716 Use any of the following methods to manage the NBG6716. WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your ZyXEL Device. Web Configurator. This is recommended for everyday management of the NBG6716 using a

(supported) web browser. 14 NBG6716 Users Guide Chapter 1 Introduction 1.4 Good Habits for Managing the NBG6716 Do the following things regularly to make the NBG6716 more secure and to manage the NBG6716 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 NBG6716 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG6716. You could simply restore your last configuration. 1.5 Resetting the NBG6716 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 NBG6716 to reload the factory-default configuration file. This means that you will lose all configurations that you had previously saved, the password will be reset to 1234 and the IP address will be reset to 192.168.1.1. 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 NBG6716. Press the RESET button for longer than five seconds to set the NBG6716 back to its factory-default configurations. 1.6 The WPS Button Your NBG6716 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) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves. You can use the WPS button (

) on the front panel of the NBG6716 to activate WPS in order to NBG6716 Users Guide 15 Chapter 1 Introduction 1 Make sure the power LED is on (not blinking). 2 Press the WPS button for more than three seconds and release it. Press the WPS button on another WPS-enabled device within range of the NBG6716. Note: You must activate WPS in the NBG6716 and in another wireless device within two minutes of each other. For more information on using WPS, see Section 8.2 on page 57. 1.7 LEDs Look at the LED lights on the front panel to determine the status of the NBG6716. Use the LED button at the side panel of the device to turn the LED lights on or off. If you have already pushed the LED button to the ON position but none of the LEDS are on, make sure the NBG6716 is receiving power and the power is turned on. Note: The Power LED will be on even if you push the LED button to the OFF position. This is for you to determine whether the NBG6716 is powered on.

Click Back, make sure your Internet connection is working and select the right Connection Type. Contact your ISP if you are not sure of your Internet Connection type. 2.3.2 Connection Type: PPPoE Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF

(Internet Engineering Task Force) standard specifying how a host personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). 22 NBG6716 Users Guide Chapter 2 Connection Wizard One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users. Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscriber's site. By implementing PPPoE directly on the NBG6716 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6716 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access. Figure 10 Internet Connection Type: PPPoE The following table describes the labels in this screen.

Set Up a Wireless Network with WPS Configure Wireless Security without WPS Using Multiple SSIDs on the NBG6716 8.2 Set Up a Wireless Network with WPS This section gives you an example of how to set up wireless network using WPS. This example uses the NBG6716 as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card). There are two WPS methods for creating a secure connection. This tutorial shows you how to do both. Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 8.2.1 on page 57.This is the easier method. PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN

(Personal Identification Number) in the NBG6716s interface. See Section 8.2.2 on page 58. This is the more secure method, since one device can authenticate the other. 8.2.1 Push Button Configuration (PBC) 1 Make sure that your NBG6716 is turned on. Make sure the WIFI button (at the side panel of the NBG6716) 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 NBG6716s Web Configurator and press the Push Button in the Configuration >

Network > Wireless LAN 2.4G > WPS Station screen. NBG6716 Users Guide 57 Chapter 8 Tutorials Note: Your NBG6716 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. You must press the second button within two minutes of pressing the first one. The NBG6716 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 NBG6716 securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG6716 and wireless client (the NWD210N in this example). Figure 41 Example WPS Process: PBC Method Wireless Client Access Point WITHIN 2 MINUTES SECURITY INFO COMMUNICATION 8.2.2 PIN Configuration When you use the PIN configuration method, you need to use both NBG6716s configuration interface and the clients utilities. Launch your wireless clients configuration utility. Go to the WPS settings and select the PIN method to get a PIN number. Enter the PIN number to the PIN field in the Configuration > Network > Wireless LAN 2.4G >

WPS Station screen on the NBG6716. NBG6716 Users Guide 1 2 58 Chapter 8 Tutorials 3 Click Start buttons (or button next to the PIN field) on both the wireless client utility screen and the NBG6716s WPS Station screen within two minutes. The NBG6716 authenticates the wireless client and 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 NBG6716 securely. The following figure shows you the example to set up wireless network and security on NBG6716 and wireless client (ex. NWD210N in this example) by using PIN method. Figure 42 Example WPS Process: PIN Method Wireless Client Access Point WITHIN 2 MINUTES 8.3 Configure Wireless Security without WPS This example shows you how to configure wireless security settings with the following parameters on your NBG6716.

If you are able to access the web site, your wireless connection is successfully configured. 8.4 Using Multiple SSIDs on the NBG6716 You can configure more than one SSID on a NBG6716. See Section 11.4 on page 97. This allows you to configure multiple independent wireless networks on the NBG6716 as if there were multiple APs (virtual APs). Each virtual AP has its own SSID, wireless security type and MAC filtering settings. That is, each SSID on the NBG6716 represents a different access point/wireless network to wireless clients in the network. Clients can associate only with the SSIDs for which they have the correct security settings. Clients using different SSIDs can access the Internet and the wired network behind the NBG6716 (such as a printer). NBG6716 Users Guide 63 Chapter 8 Tutorials For example, you may set up three wireless networks (A, B and C) in your office. A is for workers, B is for guests and C is specific to a VoIP device in the meeting room.

(Section 10.5 on page 82). 10.3 What You Need To Know The information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your NBG6716. NBG6716 Users Guide 76 10.3.1 Configuring Your Internet Connection Encapsulation Method Chapter 10 WAN Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password (and service name) for user authentication. WAN IP Address The WAN IP address is an IP address for the NBG6716, which makes it accessible from an outside network. It is used by the NBG6716 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG6716 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 NBG6716 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 NBG6716s 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. NBG6716 Users Guide 77 Chapter 10 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 49 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 NBG6716 supports both IGMP version 1

(IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the NBG6716 queries all directly connected networks to gather group membership. After that, the NBG6716 periodically updates this information. IP multicasting can be enabled/

disabled on the NBG6716 WAN interface in the Web Configurator (WAN). Select None to disable IP multicasting on these interfaces. 10.4 Internet Connection Use this screen to change your NBG6716s Internet access settings. Click Network > WAN from the Configuration menu.

Click Cancel to begin configuring this screen afresh. 10.4.2 PPPoE Encapsulation The NBG6716 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard

(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. By implementing PPPoE directly on the NBG6716 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6716 does that part of the task. Furthermore, with NAT, all of the LANs computers will have access. 80 NBG6716 Users Guide This screen displays when you select PPPoE encapsulation. Figure 51 Network > WAN > Internet Connection: PPPoE Encapsulation Chapter 10 WAN The following table describes the labels in this screen.

NBG6716 Users Guide 83 CHAPTER 11 Wireless LAN 11.1 Overview This chapter discusses how to configure the wireless network settings in your NBG6716. The NBG6716 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 53 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 NBG6716 is the AP. NBG6716 Users Guide 84 Chapter 11 Wireless LAN 11.1.1 What You Can Do Use the General screen to turn the wireless connection on or off, set up wireless security between the NBG6716 and the wireless clients, and make other basic configuration changes

(Section 11.2 on page 89). Use the More AP screen to set up multiple wireless networks on your NBG6716 (Section 11.4 on page 97). Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from connecting to the NBG6716 (Section 11.5 on page 100). Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 11.6 on page 102). Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 11.7 on page 102). Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 11.8 on page 103). Use the WPS Station screen to add a wireless station using WPS (Section 11.9 on page 105). Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 11.10 on page 105). 11.1.2 What You Should Know Every wireless network must follow these basic guidelines. Every wireless client in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentity. If two wireless networks overlap, they should use different channels. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess. This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network. NBG6716 Users Guide 85 Chapter 11 Wireless LAN MAC Address Filter Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate 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. 86 NBG6716 Users Guide The types of encryption you can choose depend on the type of user authentication. (See page 86 for information about this.) Chapter 11 Wireless LAN Table 30 Types of Encryption for Each Type of Authentication Weakest NO AUTHENTICATION No Security RADIUS SERVER WPA Static WEP WPA-PSK Strongest WPA2-PSK WPA2 For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK. Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network. Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly. Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database. When you select WPA2 or WPA2-PSK in your NBG6716, 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 NBG6716. 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 NBG6716 (Z), but not other networks connected to the Z. In the following figure, a guest user can access the Internet from the guest wireless network A via Z but not the home or company network N. Note: The home or company network N and Guest WLAN network are independent networks. Note: Only Router mode supports guest WLAN. NBG6716 Users Guide 87 Chapter 11 Wireless LAN Figure 54 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 55 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 88 NBG6716 Users Guide Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 8.2 on page 57. Chapter 11 Wireless LAN 11.2 General Wireless LAN Screen Use this screen to configure the SSID and wireless security of the wireless LAN. Note: If you are configuring the NBG6716 from a computer connected to the wireless LAN and you change the NBG6716s 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 NBG6716s new settings. Click Network > Wireless LAN 2.4G/5G to open the General screen.

DESCRIPTION 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 NBG6716 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 NBG6716 is currently using. Auto Channel Selection Operating Channel Channel Width Select the wireless channel width used by NBG6716. A standard 20MHz 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 NBG6716 to adjust the channel bandwidth automatically. 40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless clients must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. Select 20 MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding. 802.11 Mode If you are in the Wireless LAN 2.4G > General screen, you can select from the following:

The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/

WPA2-PSK key management) or RADIUS server (if using WPA/WPA2 key management) sends a new group key out to all clients. The re-keying process is the WPA/WPA2 equivalent of automatically changing the WEP key for an AP and all stations in a WLAN on a periodic basis. Setting of the Group Key Update Timer is also supported in WPA-PSK/WPA2-PSK mode. PMK Cache Period This field is available only when you select WPA2. Specify how often wireless clients have to resend usernames and passwords in order to stay connected. Enter a time interval between 10 and 999999 minutes.

Session Timeout The key must be the same on the external authentication server and your NBG6716. The key is not sent over the network. The NBG6716 automatically disconnects a wireless client from the wireless and wired networks after a period of inactivity. The wireless client needs to send the username and password again before it can use the wireless and wired networks again. Some wireless clients may prompt users for a username and password; other clients may use saved login credentials. In either case, there is usually a short delay while the wireless client logs in to the wireless network again. Apply Cancel Enter the time in seconds from 0 to 999999.

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 70 LAN Example The LAN screens can help you configure a manage IP address, and partition your physical network into logical networks. 12.2 What You Can Do Use the IP screen to change the IP address for your NBG6716 (Section 12.4 on page 108). Use the IP Alias screen to have the NBG6716 apply IP alias to create LAN subnets (Section 12.5 on page 109). 12.3 What You Need To Know The actual physical connection determines whether the NBG6716 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. NBG6716 Users Guide 107 Chapter 12 LAN Figure 71 LAN and WAN IP Addresses The LAN parameters of the NBG6716 in router mode are preset in the factory with the following values:

IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits) DHCP server enabled with 32 client IP addresses starting from 192.168.1.33. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded Web Configurator help regarding what fields need to be configured. 12.3.1 IP Alias IP alias allows you to partition a physical network into different logical networks over the same Ethernet interface. The NBG6716 supports three logical LAN interfaces via its single physical Ethernet interface with the NBG6716 itself as the gateway for each LAN network. 12.4 LAN IP Screen Use this screen to change the IP address for your NBG6716.

NBG6716 Users Guide 109 CHAPTER 13 DHCP Server 13.1 Overview DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the NBG6716s LAN as a DHCP server or disable it. When configured as a server, the NBG6716 provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else the computer must be manually configured. 13.1.1 What You Can Do Use the General screen to enable the DHCP server (Section 13.2 on page 111). Use the Advanced screen to assign IP addresses on the LAN to specific individual computers based on their MAC Addresses (Section 13.3 on page 111). Use the Client List screen to view the current DHCP client information (Section 13.4 on page 113). 13.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. LAN TCP/IP The NBG6716 has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability. IP Pool Setup The NBG6716 is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64. This configuration leaves 31 IP addresses (excluding the NBG6716 itself) in the lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that you may have. MAC Addresses Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. Find out the MAC addresses of your network devices if you intend to add them to the DHCP Client List screen.

Defined changes to None after you click Apply. Select DNS Relay to have the NBG6716 act as a DNS proxy. The NBG6716's LAN IP address displays in the field to the right (read-only). The NBG6716 tells the DHCP clients on the LAN that the NBG6716 itself is the DNS server. When a computer on the LAN sends a DNS query to the NBG6716, the NBG6716 forwards the query to the NBG6716's system DNS server (configured in the WAN > Internet Connection screen) and relays the response back to the computer. You can only select DNS Relay for one of the three servers; if you select DNS Relay for a second or third DNS server, that choice changes to None after you click Apply. Select None if you do not want to configure DNS servers. If you do not configure a DNS server, you must know the IP address of a computer in order to access it.

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 NBG6716. 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 NBG6716, which is 192.168.1.1. Figure 77 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 NBG6716. Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the NBG6716. 14.1.1 What You Can Do Use the General screen to enable NAT (Section 14.2 on page 117). NBG6716 Users Guide 115 Chapter 14 NAT Use the Port Forwarding screen to set a default server and change your NBG6716s port forwarding settings to forward incoming service requests to the server(s) on your local network

(Section 14.3 on page 118). Use the Port Trigger screen to change your NBG6716s trigger port settings (Section 14.5.3 on page 123). 14.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. Inside/Outside This denotes where a host is located relative to the NBG6716, 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 49 NAT Definitions ITEM Inside DESCRIPTION This refers to the host on the LAN. Outside This refers to the host on the WAN. Local Global 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 116 NBG6716 Users Guide Chapter 14 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 NBG6716 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 NBG6716 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 78 How NAT Works 14.2 General Use this screen to enable NAT and set a default server. Click Network > NAT to open the General screen. Figure 79 Network > NAT > General NBG6716 Users Guide 117 Chapter 14 NAT The following table describes the labels in this screen. Table 50 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. 14.3 Port Forwarding Screen Use this screen to forward incoming service requests to the server(s) on your local network and set a default server. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded. Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP. Port forwarding allows you to define the local servers to which the incoming services will be forwarded. To change your NBG6716s port forwarding settings, click Network > NAT > Port Forwarding. The screen appears as shown. Note: If you do not assign a Default Server, the NBG6716 discards all packets received for ports that are not specified in this screen or remote management. Refer to Appendix C on page 221 for port numbers commonly used for particular services. 118 NBG6716 Users Guide Figure 80 Network > NAT > Port Forwarding Chapter 14 NAT The following table describes the labels in this screen.

NBG6716 Users Guide 121 Chapter 14 NAT 14.5 Technical Reference The following section contains additional technical information about the NBG6716 features described in this chapter. 14.5.1 NATPort Forwarding: Services and Port Numbers A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Use the Port Forwarding screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded. Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP. 14.5.2 NAT Port Forwarding Example Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 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 83 Multiple Servers Behind NAT Example 122 NBG6716 Users Guide 14.5.3 Trigger Port Forwarding Chapter 14 NAT 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 NBG6716 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 NBG6716's WAN port receives a response with a specific port number and protocol ("incoming"

port), the NBG6716 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. 14.5.4 Trigger Port Forwarding Example The following is an example of trigger port forwarding. Figure 84 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 NBG6716 to record Janes computer IP address. The NBG6716 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 NBG6716 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 NBG6716 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP

(Transfer Control Protocol/Internet Protocol). NBG6716 Users Guide 123 Chapter 14 NAT 14.5.5 Two Points To Remember About Trigger Ports 1 2 Trigger events only happen on data that is coming from inside the NBG6716 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. 124 NBG6716 Users Guide CHAPTER 15 DDNS 15.1 Overview DDNS services let you use a domain name with a dynamic IP address. 15.1.1 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 NBG6716 or a server in your network. Note: The NBG6716 must have a public global IP address and you should have your registered DDNS account information on hand. 15.2 General To change your NBG6716s DDNS, click Network > DDNS.

The NBG6716 usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the NBG6716 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 NBG6716s LAN interface. The NBG6716 routes most traffic from A to the Internet through the NBG6716s default gateway (R1). You create one static route to connect to services offered by your ISP behind router R2. You create another static route to communicate with a separate network behind a router R3 connected to the LAN. Figure 86 Example of Static Routing Topology A LAN WAN R3 R1 R2 16.2 IP Static Route Screen Click Network > Static Route to open the Static Route screen.

NBG6716 Users Guide 129 CHAPTER 17 Firewall 17.1 Overview Use these screens to enable and configure the firewall that protects your NBG6716 and your LAN from unwanted or malicious traffic. Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall:

allows traffic that originates from your LAN computers to go to all of the networks. blocks traffic that originates on the other networks from going to the LAN. The following figure illustrates the default firewall action. User A can initiate an IM (Instant Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2). However other traffic initiated from the WAN is blocked (3 and 4). Figure 89 Default Firewall Action LAN WAN A 1 2 3 4 17.1.1 What You Can Do Use the General screen to enable or disable the NBG6716s firewall (Section 17.2 on page 132). Use the Services screen enable service blocking, enter/delete/modify the services you want to block and the date/time you want to block them (Section 17.3 on page 132). 17.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. NBG6716 Users Guide 130 Chapter 17 Firewall What is a Firewall?

Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot solve every security problem. A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself. Stateful Inspection Firewall Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises. About the NBG6716 Firewall The NBG6716s 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 NBG6716's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The NBG6716 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 NBG6716 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 NBG6716 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband

(cable or DSL) modem to the Internet. The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service. Guidelines For Enhancing Security With Your Firewall Change the default password via Web Configurator. Think about access control before you connect to the network in any way, including attaching a modem to the port. Limit who can access your router. 1 2 3 NBG6716 Users Guide 131 Chapter 17 Firewall 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. 17.2 General Screen Use this screen to enable or disable the NBG6716s firewall, and set up firewall logs. Click Security

Internet content filtering allows you to create and enforce Internet access policies tailored to your needs. Content filtering is the ability to block certain web features or specific URL keywords. 18.1.1 What You Need To Know The following terms and concepts may help as you read through this chapter. Content Filtering Profiles Content filtering allows you to block certain web features, such as cookies, and/or block access to specific web sites. For example, you can configure one policy that blocks John Does access to arts and entertainment web pages. A content filtering profile conveniently stores your custom settings for the following features. Keyword Blocking URL Checking The NBG6716 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 NBG6716 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 NBG6716 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. 18.2 Content Filter Use this screen to restrict web features, add keywords for blocking and designate a trusted computer.

Used by Web servers to track usage and provide service based on ID. A server that acts as an intermediary between a user and the Internet to provide security, administrative control, and caching service. When a proxy server is located on the WAN it is possible for LAN users to circumvent content filtering by pointing to this proxy server. Enable URL Keyword Blocking The NBG6716 can block Web sites with URLs that contain certain keywords in the domain name or IP address. For example, if the keyword "bad" was enabled, all sites containing this keyword in the domain name or IP address will be blocked, e.g., URL http://

www.website.com/bad.html would be blocked. Select this check box to enable this feature. Keyword Type a keyword in this field. You may use any character (up to 64 characters). Wildcards are not allowed. You can also enter a numerical IP address. Add Click Add after you have typed a keyword. Repeat this procedure to add other keywords. Up to 64 keywords are allowed.

See the appendices for information on how to access and use the command interpreter. Domain Name or IP Address URL Checking By default, the NBG6716 checks the URLs domain name or IP address when performing keyword blocking. This means that the NBG6716 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 NBG6716 check the characters that come before the last slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking searches for keywords within www.zyxel.com.tw/news/. Use the ip urlfilter customize actionFlags 6 [disable | enable] command to extend (or not extend) the keyword blocking search to include the URL's full path. File Name URL Checking Filename URL checking has the NBG6716 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. NBG6716 Users Guide 137 Chapter 18 Content Filtering 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. 138 NBG6716 Users Guide CHAPTER 19 StreamBoost Management 19.1 Overview The NBG6716 supports the new StreamBoost technology, introduced by Qualcomm, to redistribute traffic over the NBG6716 for the best possible performance in a home network. Streamboost is smart Quality of Service (QoS). Streamboost detects traffic flows and applies traffic shaping polcies automatically. It gives each device and each application the priority and provides the exact amount of bandwidth they need at a given time. This helps free up bandwidth for other applications or connected deivces. If there is not enough bandwidth for optimal performance, Streamboost makes sure the application or device has the minimum acceptable bandwidth which is determined according to the StreamBoosts cloud-based database. Real-time application traffic (such as on-line games or communications) and video/audio streaming are given the highest priority. Downloads or torrent files are classified as best effort and placed lower than general network traffic (general browsing). In the figure below, the StreamBoost-enabled NBG6716 differentiates incoming traffic flows going from the LAN device (A) or wireless device (B) to the Internet. It shapes traffic and gives priority and allocate bandwidth according to traffic types.

NBG6716 Users Guide 149 CHAPTER 21 Universal Plug-and-Play (UPnP) 21.1 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. 21.2 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. 21.2.1 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. 21.2.2 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 NBG6716 allows multicast messages on the LAN only. NBG6716 Users Guide 150 All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. Chapter 21 Universal Plug-and-Play (UPnP) 21.3 UPnP Screen Use this screen to enable UPnP on your NBG6716. Click Management > UPnP to display the screen shown next. Figure 103 Management > UPnP The following table describes the fields in this screen. Table 64 Management > UPnP LABEL UPnP DESCRIPTION Select Enable to activate UPnP. Be aware that anyone could use a UPnP application to open the web configurator's login screen without entering the NBG6716's IP address

(although you must still enter the password to access the web configurator). Apply Cancel Click Apply to save the setting to the NBG6716. Click Cancel to return to the previously saved settings. 21.4 Technical Reference The sections show examples of using UPnP. 21.4.1 Using UPnP in Windows XP Example This section shows you how to use the UPnP feature in Windows XP.

Note: The read and write performance may be affected by amount of file-sharing traffic on your network, type of connected USB device and your USB version (1.1 or 2.0). Media Server You can set up your NBG6716 to act as a media server to provide media (like video) to DLNA-

compliant players, such as Windows Media Player, ZyXEL DMAs (Digital Media Adapters), Xboxes or PS3s. The media server and clients must have IP addresses in the same subnet. The NBG6716 media server enables you to:

Publish all folders for everyone to play media files in the USB storage device connected to the NBG6716. Use hardware-based media clients like the DMA-2500 to play the files. Note: Anyone on your network can play the media files in the published folders. No user name and password nor other form of security is required. The following figure is an overview of the NBG6716s media server feature. DLNA devices A and B can access and play files on a USB device (C) which is connected to the NBG6716 (D). Figure 113 Media Server Overview A B C D NBG6716 Users Guide 156 Chapter 22 USB Media Sharing File-Sharing Server You can also share files on a USB memory stick or hard drive connected to your NBG6716 with users on your network. The following figure is an overview of the NBG6716s file-sharing server feature. Computers A and B can access files on a USB device (C) which is connected to the NBG6716 (D). Figure 114 File Sharing Overview B A C D 22.2 What You Can Do Use the DLNA screen to use the NBG6716 as a media server and allow DLNA-compliant devices to play media files stored in the attached USB device (Section 22.5 on page 159). Use the SAMBA screen to enable file-sharing via the NBG6716 using Windows Explorer or the workgroup name. This screen also allow you to configure the workgroup name and create user accounts (Section 22.6 on page 159). Use the FTP screen to allow file sharing via the NBG6716 using FTP and create user accounts

(Section 22.7 on page 161). 22.3 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 NBG6716 can function as a DLNA-compliant media server and stream files to DLNA-compliant media clients without any configuration. NBG6716 Users Guide 157 Chapter 22 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 NBG6716 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 NBG6716 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 NBG6716. 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. 22.4 Before You Begin Make sure the NBG6716 is connected to your network and turned on. Connect the USB device to one of the NBG6716s USB ports. The NBG6716 detects the USB device and makes its contents available for browsing. If you are connecting a USB hard drive that comes with an external power supply, make sure it is connected to an appropriate power source that is on.

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 Content Filtering 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 193 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. 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. NBG6716 Users Guide 181 Chapter 24 Troubleshooting 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.
