          This scenario describes a small office or home office (SOHO) network that connects to the Internet   Notes
          by using a translated connection.
          The  network  configuration  is  simplified  through  the  use  of  the  network  address  translation
          (NAT) routing  protocol, which provides network  address translation, addressing, and name
          resolution services for SOHO network computers.
          A SOHO network has the following characteristics:
          z z  One network segment.

          z z  A single protocol: TCP/IP.
          z z  Demand-dial or dedicated-link connections to the Internet service provider (ISP).
          The following illustration shows an example of a SOHO network.
                                      Figure 7.5: SOHO Network


















          The server running Routing and Remote Access is configured with a network adapter for the
          media that is used in the home network (for example, Ethernet) and an ISDN adapter or an
          analog modem. You can use a leased line or other permanent connection technologies, such as
          xDSL and cable modems, but this scenario describes the more typical configuration that uses a
          dial-up link to a local ISP.
          This section covers:

          z z  Planning for a translated connection
          z z  Configuring a translated connection
          z z  Testing a translated connection

          7.5 Public Wireless LAN Network

          The communication network established for the purpose of connecting computer devices of
          personal use is known as the personal area network PAN (Personal Area Network).when a network
          is established by connecting phone lines to personal digital devices or PDAs (personal digital
          assistants), this communication is known as PAN (Personal Area Network). Thomas Zimmerman
          was the first research scientist to introduce the idea of Personal Area Network (PAN).
          The basic purport of  establishing PAN (Personal Area Network) is provide a communication
          channel to the individuals, who want to carry their own digital devices .however  at the same they
          want to stay in contact with the network. PAN (Personal Area Network) networks often cover
          an area of 30 feet. Personal computer devices may include palm tops mobile phones, potable
          media players, play stations and net books. These devices help a person to browse internet while
          traveling, to write notes and to send instant messages. These personal digital devices assist a
          person to develop networks and communicate via intranet, internet or even extranet. There are
