1.1 Typical Network Topology
1.2 Assumptions about the Local Area Network

While the ppp program can, and usually is, be configured to provide services to only the local FreeBSD box it can also be used to serve as a "Gateway" (or "router") between other LAN-connected resources and the Internet or other Dial-Up service.

1.1 Typical Network Topology

This guide assumes a typical Local Area Network lashed together as follows:

     
    +---------+       ----> Dial-Up Internet Connection
    | FreeBSD |       \       (i.e.: NetCom, AOL, AT&T, EarthLink,
    etc)
    |         |--------
    | "Curly" |
    |         |
    +----+----+
         |
    |----+-------------+-------------+----|  <-- Ethernet Network
         |             |             |
         |             |             |
    +----+----+   +----+----+   +----+----+
    |         |   |         |   |         |
    |  Win95  |   |   WFW   |   |  WinNT  |
    | "Larry" |   |  "Moe"  |   | "Shemp" |
    |         |   |         |   |         |
    +---------+   +---------+   +---------+
