I'm wondering if references referring to
pf in FreeBSD are applicable to
ipfw in Mac OS X Snow Leopard? I'd like to know to see if it's worthwhile to consult books on
pf for use with Mac OS.
ipfw is like as ipfw on freebsd. :)
ipfw and pf are totally different packet filtering systems. ipfw is the old BSD (Internet Protocol Firewall), and pf (packet filter) comes from the OpenBSD.
pf is much much more powerful as ipfw. In fact,
You should consult books, manuals about the "ipfw", not pf.
Btw, here are two nice free applications: NoobProof and WaterRoof - both are helpers for the OSX's ipfw. http://www.hanynet.com/noobproof/
