Mindaugas Rasiukevicius has worked on
NetBSD's new packet filter "npf" for quite some time now.
In order to make things easier for new users, he now has
also put up documentation for it.
The documentation covers
an introduction with a brief note on NPF's design
followed by elements of a NPF configuration file.
This is followed by instructions for
stateful filtering and
network address translation (NAT).
Further paragraphs describe
the extension API,
appendixes with more information.
