Diagram: Multiple IP Numbers + Router
Updated: May 29, 2001


  • This is a possible setup if your DSL/Cable ISP gives you more than one IP number.
  • The Web server and FTP server are directly connected to the Internet (WAN) and are thus vulnerable to attack.  Firewall software on each machine is a must.
  • The workstations are sharing a single WAN IP number from behind a router to add a layer of safety.
