How This Book Came to Be

After spending two years on the first edition of this book, I was relieved to finally have the book done. However, Check Point played a cruel trick on me and released FireWall-1 NG around the same time that my book came out in October 2001. That book was mostly on FireWall-1 4.1, so my book was already obsolete! People kept asking me, “So when are you going to update your book for NG?”

Another thing happened right ...
