NBG6617 User’s Guide10CHAPTER 1Introduction1.1 OverviewThis chapter introduces the main features and applications of the NBG6617.The NBG6617 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 NBG6617 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 is one USB 3.0 port on the side panel of your NBG6617. You can connect USB (version 3.0 or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6617 automatically detects the USB devices. 1.2 ApplicationsYour can have the following networks with the NBG6617:•Wired. You can connect network devices via the Ethernet ports of the NBG6617 so that they can communicate with each other and access the Internet.•Wireless. Wireless clients can connect to the NBG6617 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 NBG6617Use any of the following methods to manage the NBG6617.• 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 NBG6617.• Web Configurator. This is recommended for everyday management of the NBG6617 using a (supported) web browser.

Chapter 1 IntroductionNBG6617 User’s Guide111.4 Good Habits for Managing the NBG6617Do the following things regularly to make the NBG6617 more secure and to manage the NBG6617 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 NBG6617 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG6617. You could simply restore your last configuration.1.5 Resetting the NBG6617If 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 NBG6617 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 NBG6617.3Press the RESET button for longer than five seconds to set the NBG6617 back to its factory-default configurations.1.6 The WPS ButtonYour NBG6617 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 top panel of the NBG6617 to activate WPS in order to quickly set up a wireless network with strong security.

Chapter 1 IntroductionNBG6617 User’s Guide121Make 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 NBG6617. Note: You must activate WPS in the NBG6617 and in another wireless device within two minutes of each other.

They are Automatic - DHCP, PPPoE or Static. Configure the Internet type settings on your NBG6617 in the first part. The following screen depends on your Internet connection type. Enter the details provided by your Internet Service Provider (ISP) in the fields (if any).Check with your ISP to make sure you use the correct type. This wizard screen varies according to the connection type that you select.

Chapter 3 eaZy 123 WizardNBG6617 User’s Guide213.3.1 WAN Selection Type: Automatic - DHCPSelect the Automatic - DHCP option if your ISP did not assign you a fixed IP address.Figure 10 WAN Selection Type: Automatic - DHCP3.3.2 WAN Selection 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 NBG6617 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6617 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

This example uses the NBG6617 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 49. 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 NBG6617’s interface. See Section 8.2.2 on page 50. This is the more secure method, since one device can authenticate the other.8.2.1 Push Button Configuration (PBC)1Make sure that your NBG6617 is turned on. Make sure the WIFI button (at the rear panel of the NBG6617) 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 NBG6617’s Web Configurator and press the Push Button in the Expert > Wireless > WPS screen.

Chapter 8 TutorialsNBG6617 User’s Guide50Note: Your NBG6617 has a WPS button located on its top 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 NBG6617 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 NBG6617 securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG6617 and wireless client (the NWD210N in this example).Figure 36 Example WPS Process: PBC Method8.2.2 PIN ConfigurationWhen you use the PIN configuration method, you need to use both NBG6617’s configuration interface and the client’s utilities.1Launch your wireless client’s configuration utility.

If you are able to access the web site, your wireless connection is successfully configured.8.4 Using Guest SSIDs on the NBG6617You can configure more than one guest SSID on a NBG6617. See Section 11.4 on page 91. This allows you to configure multiple independent wireless networks on the NBG6617 as if there were multiple APs (virtual APs). Each guest SSID has its own wireless security type. That is, each SSID on the NBG6617 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 NBG6617 (such as a printer).

Chapter 8 TutorialsNBG6617 User’s Guide56For 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. 8.4.1 Configuring Security Settings of Guest SSIDsThe NBG6617 is in router mode by default.This example shows you how to configure the SSIDs with the following parameters on your NBG6617 (in router mode).Note: This tutorial assumes that you have disabled WPS in Expert > Wireless > WPS. Otherwise, the “WPA-PSK” security type is not available to configure.1Connect your computer to the LAN port of the NBG6617 using an Ethernet cable. 2The default IP address of the NBG6617 in router mode is “192.168.1.1”.

NBG6617 User’s Guide62CHAPTER 10WAN10.1 OverviewThis chapter discusses the NBG6617’s WAN screens. Use these screens to configure your NBG6617 for Internet access.A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations.Figure 39 LAN and WAN10.2 What You Can Do•Use the Internet Connection screen to enter your ISP information and set how the computer acquires its IP, DNS and WAN MAC addresses (Section 10.4 on page 65).••Use the NAT > General screen to enable NAT, set a default server and change your NBG6617’s port forwarding settings (Section 10.5.1 on page 74).•Use the NAT > Port Trigger screen to configure your NBG6617’s trigger port settings (Section 10.5.2 on page 76).•Use the NAT > Passthrough screen to configure your NBG6617’s ALGs and VPN pass-through settings (Section 10.5.3 on page 77).•Use the Dynamic DNS screen to change your NBG6617’s DDNS settings (Section 10.6 on page 78).10.3 What You Need To KnowThe information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your NBG6617.

Chapter 10 WANNBG6617 User’s Guide6310.3.1 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 NBG6617, which makes it accessible from an outside network. It is used by the NBG6617 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG6617 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 NBG6617 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 NBG6617’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 WANNBG6617 User’s Guide64MulticastTraditionally, 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 40 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 NBG6617 supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the NBG6617 queries all directly connected networks to gather group membership. After that, the NBG6617 periodically updates this information. IP multicasting can be enabled/disabled on the NBG6617 WAN interface in the Web Configurator (WAN). Select None to disable IP multicasting on these interfaces.Auto-IP ChangeWhen the NBG6617 gets a WAN IP address or a DNS server IP address which is in the same subnet as the LAN IP address 192.168.1.1, Auto-IP-Change allows the NBG6617 to change its LAN IP address to 10.0.0.1 automatically. If the NBG6617’s original LAN IP address is 10.0.0.1 and the WAN IP address is in the same subnet, such as 10.0.0.3, the NBG6617 switches to use 192.168.1.1 as its LAN IP address.Figure 41 Auto-IP-Change Example192.168.1.1 192.168.1.2310.0.0.1

Chapter 10 WANNBG6617 User’s Guide65Auto-IP-Change only works under the following conditions:• The NBG6617 must be in Router Mode (see Section 15.12 on page 146 for more information) for Auto-IP-Change to become active.• The NBG6617 is set to receive a dynamic WAN IP address.10.4 Internet Connection ScreenUse this screen to change your NBG6617’s Internet access settings.

Chapter 10 WANNBG6617 User’s Guide7010.4.2 PPPoE EncapsulationThe NBG6617 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 NBG6617 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6617 does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

NBG6617 User’s Guide80CHAPTER 11Wireless LAN11.1 OverviewThis chapter discusses how to configure the wireless network settings in your NBG6617. The NBG6617 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 Expert Mode > Wireless to configure wireless LAN 2.4G or wireless LAN 5G.See the appendices for more detailed information about wireless networks.The following figure provides an example of a wireless network.Figure 48 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 NBG6617 is the AP.

Chapter 11 Wireless LANNBG6617 User’s Guide8111.1.1 What You Can Do•Use the Wireless screen to enable or disable the 2.4GHz or 5GHz wireless LAN, set up wireless security between the NBG6617 and the wireless clients, and make other basic configuration changes (Section 11.2 on page 85).•Use the Guest Wireless screen to set up multiple wireless networks on your NBG6617 (Section 11.4 on page 91). •Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from connecting to the NBG6617 (Section 11.5 on page 93).• Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 11.6 on page 94).•Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 11.7 on page 96).•Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 11.8 on page 97).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.MAC 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.

Chapter 11 Wireless LANNBG6617 User’s Guide82You 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.The types of encryption you can choose depend on the type of user authentication. (See page 82 for information about this.)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.Table 26 Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No Security WPAWPA-PSKStrongest WPA2-PSK WPA2

Chapter 11 Wireless LANNBG6617 User’s Guide83For 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, 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 WPA, and device B supports WPA and WPA2. Therefore, you should set up WPA or WPA-PSK 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 NBG6617, 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 NBG6617.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 NBG6617 (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.

Chapter 11 Wireless LANNBG6617 User’s Guide84Figure 49 Guest Wireless LAN NetworkGuest WLAN BandwidthThe Guest WLAN Bandwidth function allows you to restrict the maximum bandwidth for the guest wireless network. Additionally, you can also define bandwidth for your home or office network. An example is shown next to define maximum bandwidth for your networks (A is Guest WLAN and N is home or company network.)Figure 50 Example: Bandwidth for Different NetworksWPSWiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification NAZ600 kbps100 kbps300 kbpsNA

Chapter 11 Wireless LANNBG6617 User’s Guide85Number) 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 49. 11.2 Wireless Screen Use this screen to configure the SSID and wireless security of the NBG6617’s default wireless LAN.Note: If you are configuring the NBG6617 from a computer connected to the wireless LAN and you change the NBG6617’s SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the NBG6617’s new settings.Click Expert Mode > Wireless.Figure 51 Expert Mode > WirelessThe following table describes the general wireless LAN labels in this screen.Table 27 Expert Mode > Wireless LABEL DESCRIPTIONWireless SetupBand Select the frequency band to set whether you want to apply the wireless and security settings to the default 2.4GHz or 5GHz wireless LAN.

The options vary depending on the frequency band and the country you are in.This option is only available if Auto Channel Selection is disabled.Operating Channel This displays the channel the NBG6617 is currently using.Channel Width Select the wireless channel width used by NBG6617.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). Because not all devices support 40 MHz channels, select Auto 20/40MHz to allow the NBG6617 to adjust the channel bandwidth automatically.40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. The wireless clients must also support 40 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. Select 20MHz 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 set Band to 2.4GHz, you can select from the following:•802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the NBG6617.
