lack in the firewall chapter

[Gabriel C. de Barros]

Hi,

i've spend two days trying to set ipfw or ipf .. before i understant that i should lower my kernel security settings before messing with the rules.

I think the handbook should mention that, at least in a footnote or something.

It was hard to find the answer, but while searching for it, i realized it's a very common new-user mistake.

Thanks,
Gabriel Barros
