Diagram: Single Computer Using NAT + Crossover Cable
Updated: May 29, 2001


Notes:

  • The server computer is acting as a router in this setup.  It has two network cards, one is connected to the DSL/Cable line, the other network card is connected to Workstation 1 by means of a crossover cable.
  • The server computer is running NAT software like ICS, Wingate, or Sygate.
  • The server actually has two IP numbers.  From the Internet or the WAN, the server is known as xxx.xxx.xxx.xxx.  However, from the inside, the server can be accessed as the WAN and the LAN (192.168.1.1).
  • You cannot access the LAN IP number from the Internet (WAN).
  • This configuration does not require a hub or switch.
