Chapter 6 Wireless LAN 6.3 Wha t Yo u Sho uld Kno w 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.
Chapter 6 Wireless LAN 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. 6.3.4 Enc ryptio n Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code.

C HA PTER 7 WAN 7.1 O ve rvie w This chapter discusses the NBG-418N v2’s WAN screens. Use these screens to configure your NBG-418N v2 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.
Chapter 7 WAN WAN IP Addre ss The WAN IP address is an IP address for the NBG-418N v2, which makes it accessible from an outside network. It is used by the NBG-418N v2 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG-418N v2 tries to access the Internet.

C HA PTER 8 LAN 8.1 O ve rvie w This chapter describes how to configure LAN settings. 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.
Chapter 8 LAN Fig ure 69 LAN and WAN IP Addresses The LAN parameters of the NBG-418N v2 are preset in the factory with the following values: • IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits) • DHCP server enabled with 32 client IP addresses starting from 192.168.1.33. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded Web Configurator help regarding what fields need to be configured. 8.2.
Chapter 8 LAN The NBG-418N v2 can get the DNS server addresses in the following ways. 1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Se rve r fields in the Wiza rd and/or WAN > Inte rne t C o nne c tio n screen. 2 If the ISP did not give you DNS server information, leave the DNS Se rve r fields set to 0.0.0.
C HA PTER 9 DHC P Se rve r 9.1 O ve rvie w 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 NBG-418N v2’s LAN as a DHCP server or disable it. When configured as a server, the NBG-418N v2 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. 9.

A PPEN DIX B IP Addre sse s a nd Sub ne tting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.
Appendix B IP Addresses and Subnetting How much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Sub ne t Ma sks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “sub-network”. A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the corresponding bit in the IP address is part of the network number.
Appendix B IP Addresses and Subnetting As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows: Table 68 Maximum Host Numbers SUBNET MASK HO ST ID SIZE MAXIMUM NUMBER O F HO STS 24 8 bits 255.0.0.0 24 bits 2 16 bits 255.255.0.0 16 bits 216 – 2 24 bits 29 bits 255.255.255.0 8 bits 255.255.255.
Appendix B IP Addresses and Subnetting Fig ure 119 Subnetting Example: Before Subnetting You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate subnetworks. The subnet mask is now 25 bits (255.255.255.128 or /25). The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25. The following figure shows the company network after subnetting. There are now two sub-networks, A and B.
Appendix B IP Addresses and Subnetting 192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126. Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254. Exa m ple : Fo ur Sub ne ts The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two subnets.

Appendix B IP Addresses and Subnetting You can obtain your IP address from the IANA, from an ISP, or it can be assigned from 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.
Appendix B IP Addresses and Subnetting Fig ure 122 Conflicting Router IP Addresses Example C o nflic ting C o m pute r a nd Ro ute r IP Addre sse s Exa m ple More than one device can not use the same IP address. In the following example, the computer and the router’s LAN port both use 192.168.1.1 as the IP address. The computer cannot access the Internet. This problem can be solved by assigning a different IP address to the computer or the router’s LAN port.

A PPEN DIX E Wire le ss LANs Wire le ss LAN To po lo g ie s This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad- ho c Wire le ss LAN C o nfig ura tio n The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
Appendix E Wireless LANs Fig ure 144 Basic Service Set ESS An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN.
Appendix E Wireless LANs Fig ure 145 Infrastructure WLAN C ha nne l A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a channel different from an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.
Appendix E Wireless LANs Fig ure 146 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations. RTS/ C TS is designed to prevent collisions due to hidden nodes.
Appendix E Wireless LANs Pre a m b le Type Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the synchronization field in a packet. Short preamble increases performance as less time sending preamble means more time for sending data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short preamble.
Appendix E Wireless LANs The following figure shows the relative effectiveness of these wireless security methods available on your NBG-418N v2. Table 78 Wireless Security Levels SEC URITY LEVEL SEC URITY TYPE Least Secure Unique SSID (Default) Unique SSID with Hide SSID Enabled MAC Address Filtering WEP Encryption IEEE802.
Appendix E Wireless LANs Type s o f RADIUS Me ssa g e s The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication: • Access-Request Sent by an access point requesting authentication. • Access-Reject Sent by a RADIUS server rejecting access. • Access-Accept Sent by a RADIUS server allowing access. • Access-Challenge Sent by a RADIUS server requesting more information in order to allow access.
Appendix E Wireless LANs However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key.
Appendix E Wireless LANs simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.
Appendix E Wireless LANs encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This all happens in the background automatically. The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC.
Appendix E Wireless LANs 3 A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and the client. 4 The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys. The keys are used to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
