NBG460N User’s Guide 31CHAPTER 1 Getting to Know Your NBG460NThis chapter introduces the main features and applications of the NBG460N.1.1 OverviewThe NBG460N acts as either an access point (AP) or a secure broadband router for all data passing between the Internet and your local network. In both AP and Router Mode you can set up a wireless network with other IEEE 802.11b/g/n compatible devices. In Router Mode a number of services such as a firewall, IPSec VPN and content filtering are also available. You can use media bandwidth management to efficiently manage traffic on your network. Bandwidth management features allow you to prioritize time-sensitive or highly important applications such as Voice over the Internet (VoIP).The NBG460N also uses MIMO (Multiple-Input, Multiple-Output) antenna technology and Gigabit Ethernet ports to deliver high-speed wireless networking.1.2 Router ModeSelect Router Mode if you need to route traffic between your network and another network such as the Internet, and require important network services such as a firewall or bandwidth management. The following figure shows computers in a WLAN connecting to the NBG460N (A), which has a DSL connection to the Internet. The NBG460N is set to Router Mode and has router features such as a built-in firewall (B).Figure 1 Secure Wireless Internet Access in Router Mode AB
Chapter 1 Getting to Know Your NBG460NNBG460N User’s Guide321.3 AP ModeSelect AP Mode if you already have a router or gateway on your network which provides network services such as a firewall or bandwidth management. The following figure shows computers in a WLAN connecting to the NBG460N, which acts as an access point (A). The NBG460N allows the wireless computers to share the same Internet access as the other computers connected to the router (B) on the same network.Figure 2 Wireless Internet Access in AP Mode 1.4 Router Features vs. AP FeaturesThe following table shows which features are available in Router or AP Mode.ABTable 1 Features Available in Router Mode vs. AP ModeFEATURE ROUTER MODE AP MODEDHCPThis allows individual clients to obtain IP addresses at start-up from a DHCP server.YES NOFirewallThis establishes a network security barrier, protecting your network from attacks and controlling access between your network and the Internet.YES NOBandwidth ManagementThis allows you to allocate network bandwidth to specific applications and or subnets.YES NOAny IP This allows a computer to access the NBG460N when the IP addresses of the computer and the NBG460N are not in the same subnet.)YES NOVPNA virtual private network (VPN) provides secure communications between sites without the expense of leased site-to-site lines.YES NOWirelessThis allows two or more devices to communicate without wires, based on IEEE 802.11 wireless standards.YES YES
Chapter 1 Getting to Know Your NBG460NNBG460N User’s Guide 331.5 Ways to Manage the NBG460NUse any of the following methods to manage the NBG460N.• Web Configurator. This is recommended for everyday management of the NBG460N using a (supported) web browser. • Command Line Interface. Line commands are mostly used for troubleshooting by service engineers. • FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.1.6 Good Habits for Managing the NBG460NDo the following things regularly to make the NBG460N more secure and to manage the NBG460N 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 NBG460N to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG460N. You could simply restore your last configuration.1.7 LEDsFigure 3 Front PanelThe following table describes the LEDs.Table 2 Front Panel LEDsLED COLOR STATUS DESCRIPTIONPOWER Green On The NBG460N is receiving power and functioning properly.

NBG460N User’s Guide 35CHAPTER 2 The WPS Button2.1 OverviewYour NBG460N supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless network. 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. 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.

Continue to Section 4.4.4 on page 58.Figure 21 Wizard Step 3: Ethernet Connection4.4.2 PPPoE ConnectionPoint-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). Table 14 Wizard Step 3: ISP ParametersCONNECTION TYPE DESCRIPTIONEthernet Select the Ethernet option when the WAN port is used as a regular Ethernet. PPPoE Select the PPP over Ethernet option for a dial-up connection. If your ISP gave you an IP address and/or subnet mask, then select PPTP.PPTP Select the PPTP option for a dial-up connection.
Chapter 4 Connection WizardNBG460N User’s Guide56One 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 NBG460N (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG460N does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.Refer to the appendix for more information on PPPoE.Figure 22 Wizard Step 3: PPPoE ConnectionThe following table describes the labels in this screen.4.4.3 PPTP ConnectionPoint-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers of data from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based networks.PPTP supports on-demand, multi-protocol, and virtual private networking over public networks, such as the Internet.Refer to the appendix for more information on PPTP.Table 15 Wizard Step 3: PPPoE ConnectionLABEL DESCRIPTIONISP Parameter for Internet AccessConnection Type Select the PPP over Ethernet option for a dial-up connection.Service Name Type the name of your service provider.User Name Type the user name given to you by your ISP.

Chapter 4 Connection WizardNBG460N User’s Guide 59You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses."Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.4.4.6 IP Address and Subnet MaskSimilar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number.Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your NBG460N, but make sure that no other device on your network is using that IP address.The subnet mask specifies the network number portion of an IP address. Your NBG460N will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the NBG460N unless you are instructed to do otherwise.4.4.7 DNS Server Address AssignmentUse DNS (Domain Name System) 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 NBG460N 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, enter them in the DNSServer fields in the Wizard and/or WAN > Internet Connection screen.
Chapter 4 Connection WizardNBG460N User’s Guide602If the ISP did not give you DNS server information, leave the DNS Server fields set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN > Internet Connection screen for the ISP to dynamically assign the DNS server IP addresses.4.4.8 WAN IP and DNS Server Address AssignmentThe following wizard screen allows you to assign a fixed WAN IP address and DNS server addresses.

B can access the Internet through the AP wirelessly.Figure 35 Wireless AP Connection to the Internet6.1.2 Configure Wireless Security Using WPS on both your NBG460N and Wireless ClientThis section gives you an example of how to set up wireless network using WPS. This example uses the NBG460N as the AP and NWD210N as the wireless client which connects to a notebook. "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 6.1.2.1 on page 74.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 NBG460N’s interface. See Section6.1.2.2 on page 75. This is the more secure method, since one device can authenticate the other.BAPInternet
Chapter 6 TutorialsNBG460N User’s Guide746.1.2.1 Push Button Configuration (PBC)1Make sure that your NBG460N is turned on and that it is within range of your computer. 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 NBG460N’s web configurator and press the Push Button button in the Network > Wireless Client >WPS Station screen. "Your NBG460N 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."It doesn’t matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The NBG460N 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 NBG460N securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG460N and wireless client (the NWD210N in this example).
Chapter 6 TutorialsNBG460N User’s Guide 75Figure 36 Example WPS Process: PBC Method6.1.2.2 PIN ConfigurationWhen you use the PIN configuration method, you need to use both NBG460N’s configuration interface and the client’s utilities.1Launch your wireless client’s configuration utility.

NBG460N User’s Guide 89CHAPTER 7 Wireless LANThis chapter discusses how to configure the wireless network settings in your NBG460N. See the appendices for more detailed information about wireless networks.7.1 Wireless Network OverviewThe following figure provides an example of a wireless network.Figure 59 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 NBG460N is the AP.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.AP
Chapter 7 Wireless LANNBG460N User’s Guide90• 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.7.2 Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.7.2.1 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.7.2.2 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.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.7.2.3 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.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 7 Wireless LANNBG460N User’s Guide 91If 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.7.2.4 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 Section 7.2.3 on page 90 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."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.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.Table 27 Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No Security WPAStatic WEPWPA-PSKStrongest WPA2-PSK WPA2
Chapter 7 Wireless LANNBG460N User’s Guide92When you select WPA2 or WPA2-PSK in your NBG460N, you can also select an option (WPA Compatible) to support WPA 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 Compatible option in the NBG460N.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. 7.3 RoamingA wireless station is a device with an IEEE 802.11a/b/g/n compliant wireless interface. An access point (AP) acts as a bridge between the wireless and wired networks. An AP creates its own wireless coverage area. A wireless station can associate with a particular access point only if it is within the access point’s coverage area.In a network environment with multiple access points, wireless stations are able to switch from one access point to another as they move between the coverage areas. This is known as roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate access point depending on the signal strength, network utilization or other factors.The roaming feature on the access points allows the access points to relay information about the wireless stations to each other. When a wireless station moves from a coverage area to another, it scans and uses the channel of a new access point, which then informs the other access points on the LAN about the change. An example is shown in Figure 60 on page 93.With roaming, a wireless LAN mobile user enjoys a continuous connection to the wired network through an access point while moving around the wireless LAN.Enable roaming to exchange the latest bridge information of all wireless stations between APs when a wireless station moves between coverage areas. Wireless stations can still associate with other APs even if you disable roaming. Enabling roaming ensures correct traffic forwarding (bridge tables are updated) and maximum AP efficiency. The AP deletes records of wireless stations that associate with other APs (Non-ZyXEL APs may not be able to perform this). 802.1x authentication information is not exchanged (at the time of writing).
Chapter 7 Wireless LANNBG460N User’s Guide 93Figure 60 Roaming ExampleThe steps below describe the roaming process.1Wireless station Y moves from the coverage area of access point AP 1 to that of access point AP 2.2Wireless station Y scans and detects the signal of access point AP 2.3Wireless station Y sends an association request to access point AP 2.4Access point AP 2 acknowledges the presence of wireless station Y and relays this information to access point AP 1 through the wired LAN. 5Access point AP 1 updates the new position of wireless station Y.7.3.1 Requirements for RoamingThe following requirements must be met in order for wireless stations to roam between the coverage areas. 1All the access points must be on the same subnet and configured with the same ESSID. 2If IEEE 802.1x user authentication is enabled and to be done locally on the access point, the new access point must have the user profile for the wireless station.3The adjacent access points should use different radio channels when their coverage areas overlap. 4All access points must use the same port number to relay roaming information. 5The access points must be connected to the Ethernet and be able to get IP addresses from a DHCP server if using dynamic IP address assignment. 7.4 Quality of ServiceThis section discusses the Quality of Service (QoS) features available on the NBG460N.
Chapter 7 Wireless LANNBG460N User’s Guide947.4.1 WMM QoSWMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless networks. It controls WLAN transmission priority on packets to be transmitted over the wireless network.WMM QoS prioritizes wireless traffic according to delivery requirements. WMM QoS is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.On APs without WMM QoS, all traffic streams are given the same access priority to the wireless network. If the introduction of another traffic stream creates a data transmission demand that exceeds the current network capacity, then the new traffic stream reduces the throughput of the other traffic streams.The NBG460N uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q tag or DSCP information in each packet’s header. The NBG460N automatically determines the priority to use for an individual traffic stream. This prevents reductions in data transmission for applications that are sensitive to latency (delay) and jitter (variations in delay).7.4.1.1 WMM QoS PrioritiesThe following table describes the WMM QoS priority levels that the NBG460N uses.7.5 General Wireless LAN Screen "If you are configuring the NBG460N from a computer connected to the wireless LAN and you change the NBG460N’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 NBG460N’s new settings.Click Network > Wireless LAN to open the General screen.Table 28 WMM QoS PrioritiesPRIORITY LEVEL DESCRIPTIONvoice(WMM_VOICE)Typically used for traffic that is especially sensitive to jitter. Use this priority to reduce latency for improved voice quality.video(WMM_VIDEO)Typically used for traffic which has some tolerance for jitter but needs to be prioritized over other data traffic.best effort(WMM_BEST_EFFORT)Typically used for traffic from applications or devices that lack QoS capabilities. Use best effort priority for traffic that is less sensitive to latency, but is affected by long delays, such as Internet surfing.background(WMM_BACKGROUND)This is typically used for non-critical traffic such as bulk transfers and print jobs that are allowed but that should not affect other applications and users. Use background priority for applications that do not have strict latency and throughput requirements.
