Hopefully people on this list can enlighten me. Are ipf and ipfw different interfaces to the same in-kernel filtering mechanism? It doesn't look like it is, but I'd like that confirmed. Is ipfw related at all to the Linux ipfw? The syntax looks the same, but the man page doesn't mention Linux. Why does FreeBSD have both? Is it because ipf is generic (ported to Solaris, IRIX, OpenBSD, etc) and ipfw is specifically designed for FreeBSD? Thanks in advance! --tal P.S.
