having the same question, I note this:

http://www.debian.org/doc/manuals/se...firewall-setup

section 5.14.3

My Knoppix 6.4.4 ends up with a message "see Knoppix menu to create persistent image" when I attempt to save firewall settings, I assume, implying there is not a persistent image.

Seeing no menu item for doing that, I assume its crippleware.

"Doesn't that leave 64,535 questions unanswered?"

LOVE IT. computer humour!! and 64,535 hackers...
