NBG6616 User’s Guide12CHAPTER 1Introduction1.1 OverviewThis chapter introduces the main features and applications of the NBG6616.The NBG6616 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/b/g/n/ac compatible devices. The NBG6616 is able to function both 2.4GHz and 5GHz networks at the same time.A range of services such as a firewall and content filtering are also available for secure Internet computing. There are two USB 2.0 ports on the side panel of your NBG6616. You can connect USB (version 2.0 or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6616 automatically detects the USB devices. Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB storage devices (such as memory sticks, USB hard drives) and/or USB devices. Other USB products are not guaranteed to function properly with the NBG6616.1.2 ApplicationsYour can have the following networks with the NBG6616:•Wired. You can connect network devices via the Ethernet ports of the NBG6616 so that they can communicate with each other and access the Internet.•Wireless. Wireless clients can connect to the NBG6616 to access network resources. You can use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-compatible device.•WAN. Connect to a broadband modem/router for Internet access.1.3 Ways to Manage the NBG6616Use any of the following methods to manage the NBG6616.• 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 NBG6616.• Web Configurator. This is recommended for everyday management of the NBG6616 using a (supported) web browser.
Chapter 1 IntroductionNBG6616 User’s Guide131.4 Good Habits for Managing the NBG6616Do the following things regularly to make the NBG6616 more secure and to manage the NBG6616 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 NBG6616 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG6616. You could simply restore your last configuration.1.5 Resetting the NBG6616If 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 NBG6616 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 Button1Make sure the power LED is on.2Press the RESET button for one to four seconds to restart/reboot the NBG6616.3Press the RESET button for longer than five seconds to set the NBG6616 back to its factory-default configurations.1.6 The WPS ButtonYour NBG6616 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) 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 NBG6616 to activate WPS in order to quickly set up a wireless network with strong security.
Chapter 1 IntroductionNBG6616 User’s Guide141Make 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 NBG6616. Note: You must activate WPS in the NBG6616 and in another wireless device within two minutes of each other. For more information on using WPS, see Section 8.2 on page 56.1.7 LEDsFigure 1 Front PanelThe following table describes the LEDs.Table 1 Front panel LEDsLED COLOR STATUS DESCRIPTIONPower Green On The NBG6616 is receiving power and functioning properly.

Chapter 3 Connection WizardNBG6616 User’s Guide213.3 Connect to InternetThe NBG6616 offers two Internet connection types. They are IPoE or PPPoE. The wizard attempts to detect which WAN connection type you are using. Figure 7 Detecting your Internet Connection Type If the wizard does not detect a connection type, you must select one from the drop-down list box. Check with your ISP to make sure you use the correct type.Note: If you get an error message, check your hardware connections. Make sure your Internet connection is up and running.The following screen depends on your Internet connection type. Enter the details provided by your Internet Service Provider (ISP) in the fields (if any).

Chapter 3 Connection WizardNBG6616 User’s Guide243.3.2 Connection Type: PPPoEPoint-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). 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 NBG6616 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6616 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.Table 8 Internet Connection Type: PPPoELABEL DESCRIPTIONInternet Connection Type Select the PPPoE option for a dial-up connection.Get automatically from ISP Select this radio button if your ISP did not assign you a fixed IP address.Use Fixed IP Address Select this radio button, provided by your ISP to give the NBG6616 a fixed, unique IP address.

NBG6616 User’s Guide56CHAPTER 8Tutorials8.1 OverviewThis chapter provides tutorials for setting up your NBG6616.•Set Up a Wireless Network Using WPS•Connect to NBG6616 Wireless Network without WPS•Using Multiple SSIDs on the NBG66168.2 Set Up a Wireless Network Using WPSThis section gives you an example of how to set up wireless network using WPS. This example uses the NBG6616 as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card).There are two WPS methods for creating a secure connection via the web configurator or utility. This tutorial shows you how to do both.•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 8.2.1 on page 56. 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 NBG6616’s interface. See Section 8.2.2 on page 57. This is the more secure method, since one device can authenticate the other.8.2.1 Push Button Configuration (PBC)1Make sure that your NBG6616 is turned on. Make sure the WIFI button (at the back panel of the NBG6616) 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 (Start or WPS button)4Log into NBG6616’s Web Configurator and press the Push Button in the Configuration > Network > Wireless LAN 2.4G > WPS Station screen.
Chapter 8 TutorialsNBG6616 User’s Guide57Note: Your NBG6616 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 NBG6616 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 NBG6616 securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG6616 and wireless client (the NWD210N in this example).Figure 38 Example WPS Process: PBC Method8.2.2 PIN ConfigurationWhen you use the PIN configuration method, you need to use both NBG6616’s configuration interface and the client’s utilities.1Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method to get a PIN number.2Enter the PIN number to the PIN field in the Configuration > Network > Wireless LAN 2.4G > WPS Station screen on the NBG6616.Wireless Client Access PointSECURITY INFOCOMMUNICATIONWITHIN 2 MINUTES

If you are able to access the web site, your wireless connection is successfully configured.8.4 Using Multiple SSIDs on the NBG6616You can configure more than one SSID on a NBG6616. See Section 11.4 on page 97. This allows you to configure multiple independent wireless networks on the NBG6616 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 NBG6616 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 NBG6616 (such as a printer).

Chapter 10 WANNBG6616 User’s Guide7510.3.1 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 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 AddressThe WAN IP address is an IP address for the NBG6616, which makes it accessible from an outside network. It is used by the NBG6616 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG6616 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 NBG6616 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 NBG6616’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 Factory Default to select the factory assigned default MAC Address.Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port.
Chapter 10 WANNBG6616 User’s Guide76MulticastTraditionally, 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 46 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 NBG6616 supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the NBG6616 queries all directly connected networks to gather group membership. After that, the NBG6616 periodically updates this information. IP multicasting can be enabled/disabled on the NBG6616 WAN interface in the Web Configurator (WAN). Select None to disable IP multicasting on these interfaces.10.4 Internet ConnectionUse this screen to change your NBG6616’s Internet access settings. Click Network > WAN from the Configuration menu.

Chapter 10 WANNBG6616 User’s Guide7910.4.2 PPPoE EncapsulationThe NBG6616 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 NBG6616 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6616 does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.Set WAN MAC Address Select this option and enter the MAC address you want to use.IPv6 AddressThis is not available when you select IPv4 Only in the IPv6/IPv4 field.Obtain an IP Address AutomaticallySelect this if you want to obtain an IPv6 address from a DHCPv6 server.

NBG6616 User’s Guide84CHAPTER 11Wireless LAN11.1 OverviewThis chapter discusses how to configure the wireless network settings in your NBG6616. The NBG6616 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 50 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 NBG6616 is the AP.
Chapter 11 Wireless LANNBG6616 User’s Guide8511.1.1 What You Can Do•Use the General screen to turn the wireless connection on or off, set up wireless security between the NBG6616 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 NBG6616 (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 NBG6616 (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 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 11 Wireless LANNBG6616 User’s Guide86MAC 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 11 Wireless LANNBG6616 User’s Guide87The types of encryption you can choose depend on the type of user authentication. (See page 86 for information about this.)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 NBG6616, 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 NBG6616.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 NBG6616 (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.

An example is shown next to define maximum bandwidth for your networks (A is Guest WLAN and N is home or company network.)Figure 52 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

NBG6616 User’s Guide116CHAPTER 14NAT14.1 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 NBG6616. 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 NBG6616, which is 192.168.1.1.Figure 75 NAT ExampleThis chapter discusses how to configure NAT on the NBG6616.Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the NBG6616.14.1.1 What You Can Do•Use the General screen to enable NAT (Section 14.2 on page 118).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 49 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 14 NATNBG6616 User’s Guide118network 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 NBG6616 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 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 NBG6616 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 76 How NAT Works14.2 GeneralUse this screen to enable NAT and set a default server.

Chapter 14 NATNBG6616 User’s Guide119The following table describes the labels in this screen.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 NBG6616’s port forwarding settings, click Network > NAT > Port Forwarding. The screen appears as shown.Note: If you do not assign a Default Server, the NBG6616 discards all packets received for ports that are not specified in this screen or remote management.Refer to Appendix C on page 228 for port numbers commonly used for particular services.Table 50 Network > NAT > GeneralLABEL DESCRIPTIONNetwork Address Translation (NAT) Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).

Chapter 14 NATNBG6616 User’s Guide12314.5 Technical ReferenceThe following section contains additional technical information about the NBG6616 features described in this chapter.14.5.1 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 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 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 81 Multiple Servers Behind NAT Example
Chapter 14 NATNBG6616 User’s Guide12414.5.3 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 NBG6616 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 NBG6616's WAN port receives a response with a specific port number and protocol ("incoming" port), the NBG6616 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.14.5.4 Trigger Port Forwarding Example The following is an example of trigger port forwarding.Figure 82 Trigger Port Forwarding Process: Example1Jane requests a file from the Real Audio server (port 7070).2Port 7070 is a “trigger” port and causes the NBG6616 to record Jane’s computer IP address. The NBG6616 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 NBG6616 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 NBG6616 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). Jane’s computerReal Audio ServerPort 7070
Chapter 14 NATNBG6616 User’s Guide12514.5.5 Two Points To Remember About Trigger Ports1Trigger events only happen on data that is coming from inside the NBG6616 and going to the outside.2If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can’t trigger it.

NBG6616 User’s Guide128CHAPTER 16Static Route16.1 Overview This chapter shows you how to configure static routes for your NBG6616.The NBG6616 usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the NBG6616 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 NBG6616’s LAN interface. The NBG6616 routes most traffic from A to the Internet through the NBG6616’s default gateway (R1). You create one static route to connect to services offered by your ISP behind router R2. You create another static route to communicate with a separate network behind a router R3 connected to the LAN.Figure 84 Example of Static Routing Topology16.2 IP Static Route Screen Click Network > Static Route to open the Static Route screen.

By default the firewall:• allows traffic that originates from your LAN computers to go to all of the networks. • blocks traffic that originates on the other networks from going to the LAN. The following figure illustrates the default firewall action. User A can initiate an IM (Instant Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2). However other traffic initiated from the WAN is blocked (3 and 4).Figure 87 Default Firewall Action17.1.1 What You Can Do•Use the General screen to enable or disable the NBG6616’s firewall (Section 17.2 on page 133).•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 133).17.1.2 What You Need To KnowThe following terms and concepts may help as you read through this chapter.WANLAN3412A
Chapter 17 FirewallNBG6616 User’s Guide132What 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 NBG6616 FirewallThe NBG6616’s firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks.It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (click the General tab under Firewall and then click the Enable Firewall check box). The NBG6616's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The NBG6616 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 NBG6616 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 NBG6616 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet.The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service.Guidelines For Enhancing Security With Your Firewall1Change the default password via Web Configurator. 2Think about access control before you connect to the network in any way, including attaching a modem to the port. 3Limit who can access your router.
Chapter 17 FirewallNBG6616 User’s Guide1334Don'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. 17.2 General Screen Use this screen to enable or disable the NBG6616’s firewall, and set up firewall logs.

NBG6616 User’s Guide138CHAPTER 19Parental Control19.1 OverviewParental controls allow you to block specific URLs. You can also define time periods and days during which the NBG6616 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 NBG6616 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 NBG6616 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 NBG6616 would find “tw” in the domain name (www.zyxel.com.tw).

Table 68 Media Bandwidth Management Setup: ServicesSERVICE DESCRIPTIONFTP File Transfer Program enables fast transfer of files, including large files that may not be possible by e-mail.WWW The World Wide Web (WWW) is an Internet system to distribute graphical, hyper-linked information, based on Hyper Text Transfer Protocol (HTTP) - a client/server protocol for the World Wide Web. The Web is not synonymous with the Internet; rather, it is just one service on the Internet. Other services on the Internet include Internet Relay Chat and Newsgroups. The Web is accessed through use of a browser. E-Mail Electronic mail consists of messages sent through a computer network to specific groups or individuals. Here are some default ports for e-mail: • POP3 - port 110• IMAP - port 143• SMTP - port 25• HTTP - port 80VoIP (SIP) Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet.SIP is transported primarily over UDP but can also be transported over TCP. BitTorrent BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute large software and media files. BitTorrent requires you to search for a file with a searching engine yourself. It distributes files by corporation and trading, that is, the client downloads the file in small pieces and share the pieces with other peers to get other half of the file.Gaming Online gaming services lets you play multiplayer games on the Internet via broadband technology.

NBG6616 User’s Guide158CHAPTER 23Universal Plug-and-Play (UPnP)23.1 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.23.2 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. 23.2.1 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.23.2.2 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 NBG6616 allows multicast messages on the LAN only.
Chapter 23 Universal Plug-and-Play (UPnP)NBG6616 User’s Guide159All UPnP-enabled devices may communicate freely with each other without additional configuration.

Often different operating systems such as Windows or Linux have different file systems. The file-sharing feature on your NBG6616 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 NBG6616 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 NBG6616. 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.24.4 Before You BeginMake sure the NBG6616 is connected to your network and turned on.1Connect the USB device to one of the NBG6616’s USB ports. 2The NBG6616 detects the USB device and makes its contents available for browsing.

Chapter 26 TroubleshootingNBG6616 User’s Guide1897Make sure you allow the NBG6616 to be remotely accessed through the WLAN interface. Check your remote management settings.• See the chapter on Wireless LAN in the User’s Guide for more information.I set up URL keyword blocking, but I can still access a website that should be blocked.Make sure that you enable parental control in the Parental Control screen, set up rules and turn on the rules. Make sure that the keywords that you type are listed in the rule’s Keyword List.If a keyword that is listed in the Keyword List is not blocked when it is found in a URL, customize the keyword blocking using commands. See the Customizing Keyword Blocking URL Checking section in the Parental Control 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 200 for instructions on how to change your computer’s IP address.What factors may cause intermittent or unstabled wireless connection? How can I solve this problem?The following factors may cause interference:• Obstacles: walls, ceilings, furniture, and so on.• Building Materials: metal doors, aluminum studs.• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.To optimize the speed and quality of your wireless connection, you can:• Move your wireless device closer to the AP if the signal strength is low.• Reduce wireless interference that may be caused by other wireless networks or surrounding wireless electronics such as cordless phones.• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the wireless client. • Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional APs if necessary.• Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet.
Chapter 26 TroubleshootingNBG6616 User’s Guide190• Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the antennas in different directions and check which provides the strongest signal to the wireless clients. 26.7 USB Device ProblemsI cannot access or see a USB device that is connected to the NBG6616.1Disconnect the problematic USB device, then reconnect it to the NBG6616.2Ensure that the USB device has power.3Check your cable connections.4Restart the NBG6616 by disconnecting the power and then reconnecting it.5If the USB device requires a special driver, install the driver from the installation disc that came with the device.
