>"Linux Firewalls by Robert L. Ziegler... The
intended audience... is administrators of home or small office
"Mr. Ziegler's approach to firewalling is repetitive and
detail-oriented to the extreme."
"Perhaps most disturbing, however, is that this book is riddled
with both typographical and technical errors."
"Building Linux and OpenBSD Firewalls by Wes
Sonnenreich and Tom Yates is a different sort of book. It takes a
much more high-level approach, covers a wider range of topics, and
gets most of its facts right.
"The character of this book is strongly shaped by the decision
to cover both Linux and OpenBSD."
"One thing is worth bearing in mind here: both of these books
will become obsolete as soon as distributions with the 2.4 kernel
start shipping - before the end of this year."
"... somebody struggling through the process of setting up
and configuring a firewall is going to need some help. These books
are a start."
