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.
