Page 111: Network Address Translation
Network Address Translation 10.1 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.
Page 112: What You Can Do
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 NBG-416N, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Page 113 If you do not define any servers , NAT offers the additional benefit of firewall protection. With no servers defined, your NBG-416N filters out 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).

When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the NBG-416N allows multicast messages on the LAN only. All UPnP-enabled devices may communicate freely with each other without additional configuration.
Page 131: 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-416N. Make sure the computer is connected to a LAN port of the NBG-416N. Turn on your computer and the NBG-416N.

This chapter shows you how to upload a new firmware, upload or save backup configuration files and restart the NBG-416N. 17.2 What You Can Do • Use the Firmware screen to upload firmware to your NBG-416N (Section 17.3 on page 143).
Page 144 Click Upload to begin the upload process. This process may take up to two minutes. Note: Do not turn off the NBG-416N while firmware upload is in progress! After you see the Firmware Upload In Process screen, wait for several minutes before logging into the NBG-416N again.
Page 145 Chapter 17 Tools The NBG-416N automatically restarts in this time causing a temporary network disconnect. In some operating systems, you may see the following icon on your desktop. Figure 96 Network Temporarily Disconnected After two minutes, log in again and check your new firmware version in the Status screen.

17.4.1 Backup Configuration Backup configuration allows you to back up (save) the NBG-416N’s current configuration to a file on your computer. Once your NBG-416N is configured and functioning properly, it is highly recommended that you back up your configuration file before making configuration changes. The backup configuration file will be useful in case you need to return to your previous settings.
Page 147: Back To Factory Defaults
Chapter 17 Tools Note: Do not turn off the NBG-416N while configuration file upload is in progress. After you see a “configuration upload successful” screen, you must then wait one minute before logging into the NBG-416N again.

Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal. 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. NBG-416N User’s Guide...
Page 162 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. NBG-416N User’s Guide...

Page 212 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. NBG-416N User’s Guide...
Page 213 Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network. Wireless security methods available on the NBG-416N are data encryption, wireless client authentication, restricting access by device MAC address and hiding the NBG-416N identity.
Page 214 Wi-Fi Protected Access (WPA) WPA2 Most Secure Note: You must enable the same wireless security settings on the NBG-416N and on all wireless clients that you want to associate with it. 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.
Page 215 For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner. NBG-416N User’s Guide...
Page 216 The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. NBG-416N User’s Guide...

Page 218 WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration" wireless client. However, you must run Windows XP to use it. NBG-416N User’s Guide...
Page 219 The AP checks each wireless client's password and allows it to join the network only if the password matches. The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. NBG-416N User’s Guide...

An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. NBG-416N User’s Guide...
Page 221 For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omni-directional antennas mounted on a wall or ceiling, point the antenna down. For a single AP application, place omni-directional antennas as close to the center of the coverage area as possible. NBG-416N User’s Guide...
