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 8 WAN 8.3.2 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 57 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.
Chapter 8 WAN 8.3.4 Auto-Bridge In the rear panel of your NBG-417N, you can see four LAN ports (1 to 4) and one WAN port. The WAN port is for your Internet access connection, and the LAN ports are for your network devices. The WAN port has a different IP address from the LAN ports. When you enable auto-bridging in your NBG-417N, all five ports (4 LAN ports and the WAN port) share the same IP address as shown in the figure below. Figure 58 Autobridging Example IP Address: 192.168.1.

C HAPTER 11 Network Address Translation (NAT) 11.1 Overview This chapter discusses how to configure NAT on the NBG-417N. 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) • Use the Application screen (Section 11.4 on page 114) to change your NBG-417N’s port forwarding settings. • Use the Advanced screen (Section 11.5 on page 117) to change your NBG-417N’s trigger port settings. 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 70 Network > NAT > General The following table describes the labels in this screen.
Chapter 11 Network Address Translation (NAT) local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server.
Chapter 11 Network Address Translation (NAT) The following table describes the labels in this screen. Table 47 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.
Chapter 11 Network Address Translation (NAT) 11.5 NAT Advanced Screen 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 11 Network Address Translation (NAT) Table 48 Network > NAT > Advanced LABEL End Port Trigger DESCRIPTION Type a port number or the ending port number in a range of port numbers. The trigger port is a port (or a range of ports) that causes (or triggers) the NBG417N to record the IP address of the LAN computer that sent the traffic to a server on the WAN. Start Port Type a port number or the starting port number in a range of port numbers.
Chapter 11 Network Address Translation (NAT) 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 18 Universal Plug-and-Play (UPnP) 18.1 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 18 Universal Plug-and-Play (UPnP) 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. For security reasons, the NBG-417N allows multicast messages on the LAN only.
Chapter 18 Universal Plug-and-Play (UPnP) 18.5 Technical Reference The sections show examples of using UPnP. 18.5.1 Using UPnP in Windows XP Example This section shows you how to use the UPnP feature in Windows XP. You must already have UPnP installed in Windows XP and UPnP activated on the NBG-417N. Make sure the computer is connected to a LAN port of the NBG-417N.

A PPENDIX 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 115 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 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 A 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 A 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 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 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 141 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 142 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 143 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. 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 D Wireless LANs The following figure shows the relative effectiveness of these wireless security methods available on your NBG-417N. Table 81 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 D 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 D 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 D 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 D 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 D 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 D 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 145 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 D 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 or 5GHz 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. Antenna Gain Antenna gain, measured in dB (decibel), is the increase in coverage within the RF beam width.
Appendix D Wireless LANs For directional antennas, point the antenna in the direction of the desired coverage area.
A PPENDIX E Services The following table lists some commonly-used services and their associated protocols and port numbers. • Name: This is a short, descriptive name for the service. You can use this one or create a different one, if you like. • Protocol: This is the type of IP protocol used by the service. If this is TCP/UDP, then the service uses the same port number with TCP and UDP. If this is User-Defined, the Port(s) is the IP protocol number, not the port number.
