Comment IPFilter/PackerFilter on NetBSD (Score 1) 187
IPFilter or PacketFilter on NetBSD. I am a bit redundant since it was already proposed for OpenBSD and FreeBSD, but NetBSD was missing
I must add that BSD are good systems to learn. They take no initiatives and most of the time stick to common Unix tools instead of reinventing the wheel. That means for instance that knowledge acquired on NetBSD can be useful on Linux
