The User-Mode PPP dialer in FreeBSD Version 2.2 (also known as: "IIJ-PPP" ) now supports Packet Aliasing for dial up connections to the Internet. This feature, also known as "Masquerading", "IP Aliasing", or "Network Address Translation", allows a FreeBSD system to act as a dial- on-demand router between an Ethernet-based Local Area Network and an Internet Service Provider. Systems on the LAN can use the FreeBSD system to forward information between the Internet by means of a single dial-connection.
This guide explains how to:
Configure the FreeBSD system to support dial-out connections,
Share a dial-out connection with other systems in a network,
Configure Windows platforms to use the FreeBSD system as a gateway to the Internet.
While the focus of this guide is to assist in configuring IP Aliasing, it also includes specific examples of the configuration steps necessary to configure and install each individual component; each section stands alone and may be used to assist in the configuration of various aspects of FreeBSD internetworking.
