Salut! Be careful with the Ziegler scripts. They contain many errors, including typing mistakes in variable names. You will find these by running the scripts using "sh -u" or by changing "#!/bin/sh" to "#!/bin/sh -u". Ziegler's 2000 book on building Linux firewalls had extensive errata that made many (most?) of the tables in the book useless unless you applied all the corrections. I haven't checked the script you posted; but, the firewall script used in his book, posted on his web site (a year old), still hadn't been fixed when I looked in January. -- -IAN! Ian! D.
