Chapter 6 Broadband Encapsulation Be sure to use the encapsulation method required by your ISP. The Device can work in bridge mode or routing mode. When the Device is in routing mode, it supports the following methods. IP over Ethernet IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an Ethernet network, without using PPP encapsulation.
Chapter 6 Broadband Multiplexing There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP. VC-based Multiplexing In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.
Chapter 6 Broadband The following figure illustrates the relationship between PCR, SCR and MBS. Figure 28 Example of Traffic Shaping ATM Traffic Classes These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0 Specification. Constant Bit Rate (CBR) Constant Bit Rate (CBR) provides fixed bandwidth that is always available even if no data is being sent. CBR traffic is generally time-sensitive (doesn't tolerate delay).
Chapter 6 Broadband IP Address Assignment A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or static IP. However the encapsulation method assigned influences your choices for IP address and default gateway. Introduction to VLANs A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks.
Chapter 6 Broadband Multicast IP packets are transmitted in either one of 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. Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data.
Chapter 6 Broadband compose the network address. The prefix length is written as “/x” where x is a number. For example, 2001:db8:1a2b:15::1a2f:0/32 means that the first 32 bits (2001:db8) is the subnet prefix.

Chapter 7 Wireless • An “infrastructure” type of network has one or more access points and one or more wireless clients. The wireless clients connect to the access points. • An “ad-hoc” type of network is one in which there is no access point. Wireless clients connect to one another in order to exchange information. The following figure provides an example of a wireless network. Figure 43 Example of a Wireless Network The wireless network is the part in the blue circle.
Chapter 7 Wireless variety of networks to exist in the same place without interfering with one another. When you create a network, you must select a channel to use. Since the available unlicensed spectrum varies from one country to another, the number of available channels also varies. 7.10.2 Additional Wireless Terms The following table describes some wireless network terms and acronyms used in the Device’s Web Configurator.
Chapter 7 Wireless Because of the damage that can be done by a malicious attacker, it’s not just people who have sensitive information on their network who should use security. Everybody who uses any wireless network should ensure that effective security is in place. A good way to come up with effective security keys, passwords and so on is to use obscure information that you personally will easily remember, and to enter it in a way that appears random and does not include real words.
Chapter 7 Wireless wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network. 7.10.3.4 Encryption Wireless 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 authentication. (See Section 7.10.3.
Chapter 7 Wireless coincidental emitters such as electric motors or microwaves. Problems with absorption occur when physical objects (such as thick walls) are between the two radios, muffling the signal. 7.10.5 BSS A Basic Service Set (BSS) exists when all communications between wireless stations or between a wireless station and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless stations in the BSS.
Chapter 7 Wireless • You must use different keys for different BSSs. If two wireless devices have different BSSIDs (they are in different BSSs), but have the same keys, they may hear each other’s communications (but not communicate with each other). • MBSSID should not replace but rather be used in conjunction with 802.1x security. 7.10.7 Preamble 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.
Chapter 7 Wireless 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).
Chapter 7 Wireless 1 Ensure WPS is enabled on both devices. 2 Access the WPS section of the AP’s configuration interface. See the device’s User’s Guide for how to do this. 3 Look for the client’s WPS PIN; it will be displayed either on the device, or in the WPS section of the client’s configuration interface (see the device’s User’s Guide for how to find the WPS PIN - for the Device, see Section 7.5 on page 118). 4 Enter the client’s PIN in the AP’s configuration interface.
Chapter 7 Wireless The following figure shows a WPS-enabled wireless client (installed in a notebook computer) connecting to the WPS-enabled AP via the PIN method. Figure 46 Example WPS Process: PIN Method ENROLLEE REGISTRAR WPS This device’s WPS PIN: 123456 WPS Enter WPS PIN from other device: WPS START WPS START WITHIN 2 MINUTES SECURE EAP TUNNEL SSID WPA(2)-PSK COMMUNICATION 7.10.9.3 How WPS Works When two WPS-enabled devices connect, each device must assume a specific role.
Chapter 7 Wireless The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a WPS-enabled access point. Figure 47 How WPS works ACTIVATE WPS ACTIVATE WPS WITHIN 2 MINUTES WPS HANDSHAKE ENROLLEE REGISTRAR SECURE TUNNEL SECURITY INFO COMMUNICATION The roles of registrar and enrollee last only as long as the WPS setup process is active (two minutes). The next time you use WPS, a different device can be the registrar if necessary.
Chapter 7 Wireless is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security information to set up the network, since it is unconfigured and has no existing information. Figure 48 WPS: Example Network Step 1 ENROLLEE REGISTRAR SECURITY INFO AP1 CLIENT 1 In step 2, you add another wireless client to the network.
Chapter 7 Wireless In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you cannot use AP1 for the WPS handshake with the new access point. However, you know that Client 2 supports the registrar function, so you use it to perform the WPS handshake instead. Figure 50 WPS: Example Network Step 3 EXISTING CONNECTION CLIENT 1 IS EX O GC TIN ION CT E NN AP1 REGISTRAR CLIENT 2 SE CU RIT Y ENROLLEE INF O AP2 7.10.9.
Chapter 7 Wireless • When you use the PBC method, there is a short period (from the moment you press the button on one device to the moment you press the button on the other device) when any WPS-enabled device could join the network. This is because the registrar has no way of identifying the “correct” enrollee, and cannot differentiate between your enrollee and a rogue device. This is a possible way for a hacker to gain access to a network. You can easily check to see if this has happened.
C HAPT ER 8 Home Networking 8.1 Overview A Local Area Network (LAN) is a shared communication system to which many networking devices are connected. It is usually located in one immediate area such as a building or floor of a building. Use the LAN screens to help you configure a LAN DHCP server and manage IP addresses. LAN DSL 8.1.1 What You Can Do in this Chapter • Use the LAN Setup screen to set the LAN IP address, subnet mask, and DHCP settings of your Device (Section 8.2 on page 141).
Chapter 8 Home Networking 8.1.2 What You Need To Know 8.1.2.1 About LAN IP Address 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 Mask 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.
Chapter 8 Home Networking • Assigning lease times to mappings Windows Messenger is an example of an application that supports NAT traversal and UPnP.

Chapter 8 Home Networking • Some ISPs choose to disseminate the DNS server addresses using the DNS server extensions of IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The Device supports the IPCP DNS server extensions through the DNS proxy feature. Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions.
Chapter 8 Home Networking 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.

C HAPTER 10 Quality of Service (QoS) 10.1 Overview Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-ondemand.
Chapter 10 Quality of Service (QoS) 10.2 What You Need to Know The following terms and concepts may help as you read through this chapter. QoS versus Cos QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given the same priority. CoS (class of service) is a way of managing traffic in a network by grouping similar types of traffic together and treating each type as a class. You can use CoS to give different priorities to different packet types.
Chapter 10 Quality of Service (QoS) Traffic Policing Traffic policing is the limiting of the input or output transmission rate of a class of traffic on the basis of user-defined criteria. Traffic policing methods measure traffic flows against user-defined criteria and identify it as either conforming, exceeding or violating the criteria.
Chapter 10 Quality of Service (QoS) The following table describes the labels in this screen. Table 41 Network Setting > QoS > General LABEL DESCRIPTION QoS Select the Enable check box to turn on QoS to improve your network performance. WAN Managed Upstream Bandwidth Enter the amount of upstream bandwidth for the WAN interfaces that you want to allocate using QoS. The recommendation is to set this speed to match the interfaces’ actual transmission speed.

Chapter 10 Quality of Service (QoS) 10.8 Technical Reference The following section contains additional technical information about the Device features described in this chapter. IEEE 802.1Q Tag The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority.
Chapter 10 Quality of Service (QoS) DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping. DSCP (6 bits) Unused (2 bits) The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different kinds of forwarding.

C HAPTER 11 Network Address Translation (NAT) 11.1 Overview This chapter discusses how to configure NAT on the Device. 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 to a different IP address known within another network. 11.1.
Chapter 11 Network Address Translation (NAT) 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. Port Forwarding A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make visible to the outside world even though NAT makes your whole inside network appear as a single computer to the outside world.
Chapter 11 Network Address Translation (NAT) 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 72 Multiple Servers Behind NAT Example A=192.168.1.33 LAN WAN B=192.168.1.34 192.168.1.1 IP Address assigned by ISP C=192.168.1.3 D=192.168.1.36 Click Network Setting > NAT > Port Forwarding to open the following screen.

Click Add new application in the Applications screen to open the following screen. Figure 76 Applications: Add The following table describes the labels in this screen. Table 54 Applications: Add LABEL DESCRIPTION WAN Interface Select the WAN interface that you want to apply this NAT rule to. Server IP Address Enter the inside IP address of the application here.
Chapter 11 Network Address Translation (NAT) For example: Figure 77 Trigger Port Forwarding Process: Example 1 Jane requests a file from the Real Audio server (port 7070). 2 Port 7070 is a “trigger” port and causes the Device to record Jane’s computer IP address. The Device associates Jane's computer IP address with the "open" port range of 6970-7170. 3 The Real Audio server responds using a port number ranging between 6970-7170. 4 The Device forwards the traffic to Jane’s computer IP address.
Chapter 11 Network Address Translation (NAT) Table 55 Network Setting > NAT > Port Triggering (continued) LABEL DESCRIPTION Open Start Port The open port is a port (or a range of ports) that a server on the WAN uses when it sends out a particular service. The Device forwards the traffic with this port (or range of ports) to the client computer on the LAN that requested the service. This is the first port number that identifies a service.
Chapter 11 Network Address Translation (NAT) Table 56 Port Triggering: Configuration Add/Edit (continued) LABEL DESCRIPTION Open Start Port The open port is a port (or a range of ports) that a server on the WAN uses when it sends out a particular service. The Device forwards the traffic with this port (or range of ports) to the client computer on the LAN that requested the service. Type a port number or the starting port number in a range of port numbers.
Chapter 11 Network Address Translation (NAT) 11.6 The ALG Screen Some NAT routers may include a SIP Application Layer Gateway (ALG). A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses embedded in the data stream. When the Device registers with the SIP register server, the SIP ALG translates the Device’s private IP address inside the SIP data stream to a public IP address. You do not need to use STUN or an outbound proxy if your Device is behind a SIP ALG.
Chapter 11 Network Address Translation (NAT) The following table describes the fields in this screen. Table 59 Network Setting > NAT > Address Mapping LABEL DESCRIPTION Add new rule Click this to create a new rule. Set This is the index number of the address mapping set. Local Start IP This is the starting Inside Local IP Address (ILA). Local End IP This is the ending Inside Local IP Address (ILA). If the rule is for all local IP addresses, then this field displays 0.0.0.
Chapter 11 Network Address Translation (NAT) The following table describes the fields in this screen. Table 60 Address Mapping: Add/Edit LABEL DESCRIPTION Type Choose the IP/port mapping type from one of the following. One-to-One: This mode maps one local IP address to one global IP address. Note that port numbers do not change for the One-to-one NAT mapping type. Many-to-One: This mode maps multiple local IP addresses to one global IP address. This is equivalent to SUA (i.e.
Chapter 11 Network Address Translation (NAT) Note that inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. Thus, 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.
Chapter 11 Network Address Translation (NAT) 11.8.3 How NAT Works Each 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.
Chapter 11 Network Address Translation (NAT) 11.8.4 NAT Application The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using IP alias) behind the Device can communicate with three distinct WAN networks. Figure 85 NAT Application With IP Alias Port Forwarding: Services and Port Numbers The most often used port numbers are shown in the following table. Please refer to RFC 1700 for further information about port numbers.
Chapter 11 Network Address Translation (NAT) Port Forwarding Example Let'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 86 Multiple Servers Behind NAT Example A=192.168.1.33 192.168.1.1 B=192.168.1.
C HAPTER 12 Dynamic DNS Setup 12.1 Overview DNS DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it. In addition to the system DNS server(s), each WAN interface (service) is set to have its own static or dynamic DNS server list.
Chapter 12 Dynamic DNS Setup 12.1.2 What You Need To Know DYNDNS Wildcard Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname. If you have a private WAN IP address, then you cannot use Dynamic DNS. 12.2 The DNS Entry Screen Use this screen to view and configure DNS routes on the Device.

C HAPTER 13 Interface Group 13.1 Overview By default, all LAN and WAN interfaces on the Device are in the same group and can communicate with each other. Create interface groups to have the Device assign the IP addresses in different domains to different groups. Each group acts as an independent network on the Device. This lets devices connected to an interface group’s LAN interfaces communicate through the interface group’s WAN or LAN interfaces but not other WAN or LAN interfaces. 13.1.
Chapter 13 Interface Group In the following example, the client that sends packets with the DHCP Vendor ID option set to MSFT 5.0 (meaning it is a Windows 2000 DHCP client) is assigned the IP address 192.168.2.2 and uses the WAN VDSL_PoE/ppp0.1 interface. Figure 90 Interface Grouping Application Default: ETH 2~4 192.168.1.x/24 eth10.0 Internet VDSL_PoE/ppp0.1 192.168.2.x/24 DHCP Vendor ID option: MSFT 5.0 Click Network Setting > Interface Group to open the following screen.

C HAPTER 15 Firewall 15.1 Overview This chapter shows you how to enable and configure the Device’s security settings. Use the firewall to protect your Device and network from attacks by hackers on the Internet and control access to it. By default the firewall: • allows traffic that originates from your LAN computers to go to all other networks. • blocks traffic that originates on other networks from going to the LAN. The following figure illustrates the default firewall action.
Chapter 15 Firewall 15.1.2 What You Need to Know SYN Attack A SYN attack floods a targeted system with a series of SYN packets. Each packet causes the targeted system to issue a SYN-ACK response. While the targeted system waits for the ACK that follows the SYN-ACK, it queues up all outstanding SYN-ACK responses on a backlog queue. SYNACKs are moved off the queue only when an ACK comes back or when an internal timer terminates the three-way handshake.

A PPENDIX B IP Addresses and Subnetting 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 The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID. Figure 181 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask.
Appendix B IP Addresses and Subnetting Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes. Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks.
Appendix B IP Addresses and Subnetting The following table shows some possible subnet masks using both notations. Table 114 Alternative Subnet Mask Notation SUBNET MASK ALTERNATIVE NOTATION LAST OCTET (BINARY) LAST OCTET (DECIMAL) 255.255.255.0 /24 0000 0000 0 255.255.255.128 /25 1000 0000 128 255.255.255.192 /26 1100 0000 192 255.255.255.224 /27 1110 0000 224 255.255.255.240 /28 1111 0000 240 255.255.255.248 /29 1111 1000 248 255.255.255.
Appendix B IP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two subnetworks, A and B. Figure 183 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address). 192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.

Table 120 24-bit Network Number Subnet Planning NO. “BORROWED” HOST BITS SUBNET MASK NO. SUBNETS NO.
Appendix B IP Addresses and Subnetting Configuring IP Addresses 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.

Ad-hoc Wireless LAN Configuration 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 D Wireless LANs disabled, wireless client A and B can still access the wired network but cannot communicate with each other. Figure 195 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 D Wireless LANs An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate. Figure 196 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area.
Appendix D Wireless LANs cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 197 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.
Appendix D Wireless LANs If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. IEEE 802.11g Wireless LAN IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range.
Appendix D Wireless LANs IEEE 802.1x In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are: • User based identification that allows for roaming.
Appendix D Wireless LANs • Accounting-Request Sent by the access point requesting accounting. • Accounting-Response Sent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access.
Appendix D Wireless LANs EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the serverside authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2.
Appendix D Wireless LANs WPA and WPA2 Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA or WPA2 and WEP are improved data encryption and user authentication. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption.
Appendix D Wireless LANs password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP) User Authentication WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database.
Appendix D Wireless LANs 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. Figure 198 WPA(2) with RADIUS Application Example WPA(2)-PSK Application Example A WPA(2)-PSK application looks as follows.
Appendix D Wireless LANs Security Parameters Summary Refer to this table to see what other security parameters you should configure for each authentication method or key management protocol type. MAC address filters are not dependent on how you configure these security features.

Appendix D Wireless LANs 2.5%. For an unobstructed outdoor site, each 1dB increase in gain results in a range increase of approximately 5%. Actual results may vary depending on the network environment. Antenna gain is sometimes specified in dBi, which is how much the antenna increases the signal power compared to using an isotropic antenna. An isotropic antenna is a theoretical perfect antenna that sends out radio signals equally well in all directions.

A PPENDIX E IPv6 Overview IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. IPv6 Addressing The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000. IPv6 addresses can be abbreviated in two ways: • Leading zeros in a block can be omitted.
Appendix E IPv6 Global Address A global address uniquely identifies a device on the Internet. It is similar to a “public IP address” in IPv4. A global unicast address starts with a 2 or 3. Unspecified Address An unspecified address (0:0:0:0:0:0:0:0 or ::) is used as the source address when a device does not have its own address. It is similar to “0.0.0.0” in IPv4. Loopback Address A loopback address (0:0:0:0:0:0:0:1 or ::1) allows a host to send packets to itself. It is similar to “127.0.0.1” in IPv4.
Appendix E IPv6 Table 128 Reserved Multicast Address (continued) MULTICAST ADDRESS FF08:0:0:0:0:0:0:0 FF09:0:0:0:0:0:0:0 FF0A:0:0:0:0:0:0:0 FF0B:0:0:0:0:0:0:0 FF0C:0:0:0:0:0:0:0 FF0D:0:0:0:0:0:0:0 FF0E:0:0:0:0:0:0:0 FF0F:0:0:0:0:0:0:0 Subnet Masking Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F).
Appendix E IPv6 the time T2 is reached and the server does not respond, the client sends a Rebind message to any available server (S2). For an IA_TA, the client may send a Renew or Rebind message at the client's discretion. T2 T1 Renew Renew to S1 to S1 Renew Renew to S1 to S1 Renew to S1 Renew to S1 Rebind to S2 Rebind to S2 DHCP Relay Agent A DHCP relay agent is on the same network as the DHCP clients and helps forward messages between the DHCP server and clients.
Appendix E IPv6 • Neighbor advertisement: A response from a node to announce its link-layer address. • Router solicitation: A request from a host to locate a router that can act as the default router and forward packets. • Router advertisement: A response to a router solicitation or a periodical multicast advertisement from a router to advertise its presence and other parameters. IPv6 Cache An IPv6 host is required to have a neighbor cache, destination cache, prefix list and default router list.
Appendix E IPv6 Example - Enabling IPv6 on Windows XP/2003/Vista By default, Windows XP and Windows 2003 support IPv6. This example shows you how to use the ipv6 install command on Windows XP/2003 to enable IPv6. This also displays how to use the ipconfig command to see auto-generated IP addresses.

Appendix E IPv6 4 Double click Dibbler - a DHCPv6 client. 5 Click Start and then OK. 6 Now your computer can obtain an IPv6 address from a DHCPv6 server. Example - Enabling IPv6 on Windows 7 Windows 7 supports IPv6 by default. DHCPv6 is also enabled when you enable IPv6 on a Windows 7 computer. To enable IPv6 in Windows 7: 1 Select Control Panel > Network and Sharing Center > Local Area Connection. 2 Select the Internet Protocol Version 6 (TCP/IPv6) checkbox to enable it.
Appendix E IPv6 4 Click Close to exit the Local Area Connection Status screen. 5 Select Start > All Programs > Accessories > Command Prompt. 6 Use the ipconfig command to check your dynamic IPv6 address. This example shows a global address (2001:b021:2d::1000) obtained from a DHCP server.
