CHAPTER 9 LAN 9.1 Overview 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 9 LAN 9.2 What You Need To Know The actual physical connection determines whether the NBG-416N ports are LAN or WAN ports. There are two separate IP networks, one inside the LAN network and the other outside the WAN network as shown next. Figure 54 LAN and WAN IP Addresses The LAN parameters of the NBG-416N are preset in the factory with the following values: • IP address of 192.168.1.1 with subnet mask of 255.255.255.

CHAPTER 11 Network Address Translation (NAT) 11.1 Overview This chapter discusses how to configure NAT on the NBG-416N. 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. Each packet has two addresses – a source address and a destination address.
Chapter 11 Network Address Translation (NAT) For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT). Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the NBG-416N. 11.2 What You Can Do • Use the General screen to enable NAT and set a default server (Section 11.3 on page 104). • Use the Application screen to change your NBG-416N’s port forwarding settings (Section 11.4 on page 105).
Chapter 11 Network Address Translation (NAT) Table 40 NAT Definitions (continued) ITEM DESCRIPTION Local This refers to the packet address (source or destination) as the packet travels on the LAN. Global This refers to the packet address (source or destination) as the packet travels on the WAN. Note: NAT never changes the IP address (either local or global) of an outside host.
Chapter 11 Network Address Translation (NAT) so incoming reply packets can have their original values restored. The following figure illustrates this. Figure 60 How NAT Works 11.3 General NAT Screen Use this screen to enable NAT and set a default server. Click Network > NAT to open the General screen. Figure 61 Network > NAT > General The following table describes the labels in this screen.
Chapter 11 Network Address Translation (NAT) Table 41 Network > NAT > General (continued) LABEL Server IP Address DESCRIPTION In addition to the servers for specified services, NAT supports a default server. A default server receives packets from ports that are not specified in the Application screen. If you do not assign a Default Server IP address, the NBG-416N discards all packets received for ports that are not specified in the Application screen or remote management.
Chapter 11 Network Address Translation (NAT) Refer to Appendix E on page 205 for port numbers commonly used for particular services. Figure 62 Network > NAT > Application The following table describes the labels in this screen.

Note: 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. 11.5.
CHAPTER 12 Firewall 12.1 Overview Use these screens to enable and configure the firewall that protects your NBG416N 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 12 Firewall • Use the Services screen to enable or disable ICMP and VPN passthrough features (Section 12.5 on page 111). 12.3 What You Need To Know The NBG-416N’s firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks. 12.3.

CHAPTER 14 Universal Plug-and-Play (UPnP) 14.1 Overview This chapter introduces the UPnP feature in the Web Configurator. Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use.
Chapter 14 Universal Plug-and-Play (UPnP) See the NAT chapter for more information on NAT. Cautions with UPnP The automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. When a UPnP device joins a network, it announces its presence with a multicast message.
Chapter 14 Universal Plug-and-Play (UPnP) The following table describes the labels in this screen. Table 46 Management > UPnP > General LABEL DESCRIPTION Enable the Universal Plug and Play (UPnP) Feature Select this check box to activate UPnP.

APPENDIX A 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 A 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 95 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 A IP Addresses and Subnetting Table 55 Subnet Mask - Identifying Network Number Network Number 1ST OCTET: 2ND OCTET: 3RD OCTET: 4TH OCTET (192) (168) (1) (2) 11000000 10101000 00000001 Host ID 00000010 By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.
Appendix A 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 57 Maximum Host Numbers SUBNET MASK HOST ID SIZE 8 bits 24 bits 255.0.0.0 16 bits 255.255.0.0 24 bits 255.255.255.0 29 bits 255.255.255.
Appendix A IP Addresses and Subnetting Subnetting You can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons. In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.
Appendix A IP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two sub-networks, A and B. Figure 97 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 A IP Addresses and Subnetting Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a host ID of all zeroes is the subnet itself, all ones is the subnet’s broadcast address). Table 59 Subnet 1 IP/SUBNET MASK NETWORK NUMBER LAST OCTET BIT VALUE IP Address (Decimal) 192.168.1. 0 IP Address (Binary) 11000000.10101000.00000001. 00000000 Subnet Mask (Binary) 11111111.11111111.11111111. 11000000 Subnet Address: 192.168.1.0 Lowest Host ID: 192.168.1.

APPENDIX D 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 stations (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 with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other. Figure 130 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 stations within the same ESS must have the same ESSID in order to communicate. Figure 131 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area.
Appendix D Wireless LANs wireless gateway, but out-of-range of each other, so they 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 132 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel.
Appendix D Wireless LANs Fragmentation Threshold A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames. A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.
Appendix D Wireless LANs several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows: Table 66 IEEE 802.11g DATA RATE (MBPS) MODULATION 1 DBPSK (Differential Binary Phase Shift Keyed) 2 DQPSK (Differential Quadrature Phase Shift Keying) 5.5 / 11 CCK (Complementary Code Keying) 6/9/12/18/24/36/ 48/54 OFDM (Orthogonal Frequency Division Multiplexing) IEEE 802.1x In June 2001, the IEEE 802.
Appendix D Wireless LANs 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. • Access-Challenge Sent by a RADIUS server requesting more information in order to allow access.
Appendix D 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 D Wireless LANs If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, 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 D Wireless LANs TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This all happens in the background automatically.
Appendix D Wireless LANs 21.0.2 WPA(2)-PSK Application Example A WPA(2)-PSK application looks as follows. 1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters (including spaces and symbols). 2 The AP checks each wireless client's password and (only) allows it to join the network if the password matches. 3 The AP derives and distributes keys to the wireless clients.
Appendix D Wireless LANs Security Parameters Summary Refer to this table to see what other security parameters you should configure for each Authentication Method/ key management protocol type. MAC address filters are not dependent on how you configure these security features.

Appendix F Open Software Announcements guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it.
Appendix F Open Software Announcements applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library.
Appendix F Open Software Announcements A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms.
Appendix F Open Software Announcements argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application.
Appendix F Open Software Announcements readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5.
Appendix F Open Software Announcements as a reference directing the user to the copy of this License.
Appendix F Open Software Announcements the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above.
Appendix F Open Software Announcements It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices.
Appendix F Open Software Announcements PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16.
