The following figure provides an example of a wireless network. Figure 77 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients.
Chapter 15 Wireless LAN • Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 15.5 on page 136). • Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 15.6 on page 137). • Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 15.7 on page 137). • Use the WPS Station screen to add a wireless station using WPS (Section 15.8 on page 139).
Chapter 15 Wireless LAN 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).
Chapter 15 Wireless LAN 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.

C HAPTER 16 IPv6 16.1 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. • See Appendix G on page 309 for more information on IPv6. 16.1.1 What You Need to Know 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.
Chapter 16 IPv6 When IPv6 is enabled on a device, its interface automatically generates a link-local address (beginning with fe80). When the interface is connected to a network with a router and the NBG4615 is set to automatically obtain an IPv6 network prefix from the router for the interface, it generates 3another address which combines its interface ID and global and subnet information advertised from the router. This is a routable global IP address.

C HAPTER 17 WAN 17.1 Overview This chapter discusses the NBG4615’s WAN screens. Use these screens to configure your NBG4615 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 94 LAN and WAN 17.
Chapter 17 WAN 17.3.1 Configuring Your Internet Connection Encapsulation Method Encapsulation 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).
Chapter 17 WAN 17.3.2 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. Figure 95 Multicast Example In 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.

C HAPTER 20 NAT 20.1 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. The figure below is a simple illustration of a NAT network.
Chapter 20 NAT • Use the Advanced screen to change your NBG4615’s trigger port settings (Section 20.5.3 on page 178). 20.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. Inside/Outside This denotes where a host is located relative to the NBG4615, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Chapter 20 NAT all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT). 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.
Chapter 20 NAT The following table describes the labels in this screen. Table 69 Network > NAT > General LABEL DESCRIPTION NAT Setup Enable Network Address Translation Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet). Select the check box to enable NAT.
Chapter 20 NAT The following table describes the labels in this screen. Table 70 Network > NAT > Application LABEL DESCRIPTION Add Application Rule Active Select the check box to enable this rule and the requested service can be forwarded to the host with a specified internal IP address. Clear the checkbox to disallow forwarding of these ports to an inside server without having to delete the entry.

Note: Only one LAN computer can use a trigger port (range) at a time. Figure 112 Network > NAT > Advanced The following table describes the labels in this screen. Table 71 Network > NAT > Advanced LABEL DESCRIPTION # This is the rule index number (read-only). Name Type a unique name (up to 15 characters) for identification purposes.
Chapter 20 NAT 20.5 Technical Reference The following section contains additional technical information about the NBG4615 features described in this chapter. 20.5.1 NATPort Forwarding: Services and Port Numbers A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.
Chapter 20 NAT 20.5.3 Trigger Port Forwarding Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address.
Chapter 20 NAT 20.5.5 Two Points To Remember About Trigger Ports 1 Trigger events only happen on data that is going coming from inside the NBG4615 and going to the outside. 2 If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can’t trigger it.

C HAPTER 24 Firewall 24.1 Overview Use these screens to enable and configure the firewall that protects your NBG4615 and your LAN from unwanted or malicious traffic. Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall: • allows traffic that originates from your LAN computers to go to all of the networks. • blocks traffic that originates on the other networks from going to the LAN.
Chapter 24 Firewall What is a Firewall? Originally, the term “firewall” referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot solve every security problem.
Chapter 24 Firewall 4 Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5 For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces.

A PPENDIX C 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 C 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 167 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 C IP Addresses and Subnetting 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. Table 94 Subnet Masks BINARY DECIMAL 1ST OCTET 2ND OCTET 3RD OCTET 4TH OCTET 8-bit mask 11111111 00000000 00000000 00000000 255.0.0.0 16-bit mask 11111111 11111111 00000000 00000000 255.255.0.0 24-bit mask 11111111 11111111 11111111 00000000 255.255.255.

Appendix C IP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two subnetworks, A and B. Figure 169 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.

Appendix C IP Addresses and Subnetting IP Address Conflicts Each device on a network must have a unique IP address. Devices with duplicate IP addresses on the same network will not be able to access the Internet or other resources. The devices may also be unreachable through the network. Conflicting Computer IP Addresses Example More than one device can not use the same IP address.
Appendix C IP Addresses and Subnetting Conflicting Computer and Router IP Addresses Example 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 PPENDIX E Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. 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 E Wireless LANs disabled, wireless client A and B can still access the wired network but cannot communicate with each other. Figure 180 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 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 181 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 E 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 182 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 E 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. 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.
Appendix E Wireless LANs The following figure shows the relative effectiveness of these wireless security methods available on your NBG4615. Table 105 Wireless Security Levels SECURITY LEVEL Least Secure SECURITY TYPE Unique SSID (Default) Unique SSID with Hide SSID Enabled MAC Address Filtering WEP Encryption IEEE802.
Appendix E Wireless LANs RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server. Types of RADIUS Messages 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.
Appendix E Wireless LANs EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client. The wireless client ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. However, MD5 authentication has some weaknesses.
Appendix E Wireless LANs If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security configuration screen. You may still configure and store keys, but they will not be used while dynamic WEP is enabled. Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption.
Appendix E Wireless LANs called Rijndael. They both include a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. WPA and WPA2 regularly change and rotate the encryption keys so that the same encryption key is never used twice.
Appendix E Wireless LANs WPA(2) with RADIUS Application Example To set up WPA(2), you need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system. 1 The AP passes the wireless client's authentication request to the RADIUS server.
Appendix E Wireless LANs 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them. Figure 184 WPA(2)-PSK Authentication 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.
Appendix E Wireless LANs Positioning the antennas properly increases the range and coverage area of a wireless LAN. Antenna Characteristics Frequency An antenna in the frequency of 2.4GHz (IEEE 802.11b and IEEE 802.11g) or 5GHz (IEEE 802.11a) is needed to communicate efficiently in a wireless LAN Radiation Pattern A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area.
Appendix E Wireless LANs For directional antennas, point the antenna in the direction of the desired coverage area.

A PPENDIX G 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 G 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 G IPv6 Table 111 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 G 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 G 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 G 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.
