CHAPTER 1 Getting to Know Your NBG-460N This chapter introduces the main features and applications of the NBG-460N. 1.1 Overview The NBG-460N 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.
Chapter 1 Getting to Know Your NBG-460N 1.3 AP Mode Select 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 NBG-460N, which acts as an access point (A). The NBG-460N allows the wireless computers to share the same Internet access as the other computers connected to the router (B) on the same network.
Chapter 1 Getting to Know Your NBG-460N 1.5 Ways to Manage the NBG-460N Use any of the following methods to manage the NBG-460N. • Web Configurator. This is recommended for everyday management of the NBG-460N 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.

CHAPTER 2 The WPS Button 2.1 Overview Your NBG-460N 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).

See the appendices for more detailed information about wireless networks. 7.1 Wireless Network Overview The following figure provides an example of a wireless network. Figure 59 Example of a Wireless Network AP The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients.
Chapter 7 Wireless LAN • 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 Overview The following sections introduce different types of wireless security you can set up in the wireless network. 7.2.1 SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area.
Chapter 7 Wireless LAN 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.
Chapter 7 Wireless LAN When you select WPA2 or WPA2-PSK in your NBG-460N, 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 NBG-460N. Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption.
Chapter 7 Wireless LAN Figure 60 Roaming Example The steps below describe the roaming process. 1 Wireless station Y moves from the coverage area of access point AP 1 to that of access point AP 2. 2 Wireless station Y scans and detects the signal of access point AP 2. 3 Wireless station Y sends an association request to access point AP 2. 4 Access point AP 2 acknowledges the presence of wireless station Y and relays this information to access point AP 1 through the wired LAN.
Chapter 7 Wireless LAN 7.4.1 WMM QoS WMM (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.

Choose Factory Default to select the factory assigned default MAC Address.
Chapter 8 WAN The NBG-460N supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the NBG-460N queries all directly connected networks to gather group membership. After that, the NBG-460N periodically updates this information. IP multicasting can be enabled/disabled on the NBG-460N LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces. 8.

Chapter 8 WAN 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.

This might happen if you put the NBG-460N behind a NAT router that assigns it this IP address.
CHAPTER 9 LAN This chapter describes how to configure LAN settings. 9.1 LAN Overview A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server, manage IP addresses, and partition your physical network into logical networks. 9.1.
Chapter 9 LAN 9.2.2 IP Address and Subnet Mask Refer to the IP address and subnet mask section in the Connection Wizard chapter for this information. 9.2.3 Multicast Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1.
Chapter 9 LAN Figure 82 Any IP Example The Any IP feature does not apply to a computer using either a dynamic IP address or a static IP address that is in the same subnet as the NBG-460N’s IP address. " You must enable NAT to use the Any IP feature on the NBG-460N. Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address, also known as a Media Access Control or MAC address, on the local area network.

CHAPTER 10 DHCP 10.1 DHCP DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the NBG460N’s LAN as a DHCP server or disable it. When configured as a server, the NBG-460N provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else the computer must be manually configured. 10.2 DHCP General Screen Click Network > DHCP.

CHAPTER 11 Network Address Translation (NAT) This chapter discusses how to configure NAT on the NBG-460N. 11.1 NAT 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. 11.
Chapter 11 Network Address Translation (NAT) " 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. 11.2.
