Page 101: Network Address Translation
HAPTER Network Address Translation 10.1 Overview This chapter discusses how to configure NAT on the NBG-418N. 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.
Page 102: What You Can Do
Chapter 10 Network Address Translation 10.2 What You Can Do • Use the General screen to enable NAT and set a default server (Section 10.3 on page 103). • Use the Application screen to change your NBG-418N’s port forwarding settings (Section 10.4 on page 104).
Page 103: General Nat Screen
Chapter 10 Network Address Translation The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local network and make them accessible to the outside world.

HAPTER Dynamic DNS 11.1 Overview Dynamic Domain Name Service (DDNS) services let you use a fixed domain name with a dynamic IP address. Users can always use the same domain name instead of a different dynamic IP address that changes each time to connect to the NBG-418N or a server in your network. Note: The NBG-418N must have a public global IP address and you should have your registered DDNS account information on hand.
Page 110 Chapter 11 Dynamic DNS Table 48 Network > DDNS LABEL DESCRIPTION Host Name The host name is the domain name that the DDNS service will map to your dynamic global IP address. Type the host name fully qualified, for example, ‘yourhost.mydomain.net’. You can specify up to two host names in the field separated by a comma (",").

Page 147: Appendix A Ip Addresses And Subnetting
P PE N D I X 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.
Page 148 Appendix A IP Addresses and Subnetting Figure 108 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. Subnet Masks 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).
Page 149 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. Table 60 Subnet Masks BINARY DECIMAL 4TH OCTET OCTET...

Page 195: Appendix D Wireless Lans
P PE N D I X 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).
Page 196 Appendix D Wireless LANs Figure 134 Basic Service Set 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.
Page 197 Appendix D Wireless LANs Figure 135 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. 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.
Page 198 Appendix D Wireless LANs RTS/CTS Figure 136 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.
Page 199 Appendix D Wireless LANs 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. Short preamble increases performance as less time sending preamble means more time for sending data.
Page 200 Appendix D Wireless LANs The following figure shows the relative effectiveness of these wireless security methods available on your NBG-418N.

Page 201 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: •...
Page 202 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.
Page 203 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.
Page 204 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.
Page 205 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.
Page 206 Appendix D Wireless LANs 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 138 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.
Page 207 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 Radiation Pattern A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area.
Page 208 Appendix D Wireless LANs For directional antennas, point the antenna in the direction of the desired coverage area.
