I'm running 4.9, have recompiled the kernel with 'options ipfw2', and have recompiled libalias & ipfw with ipfw2 support. I've read through the man pages, and I can't make this particular rule work. I need to block all IP packets EXCEPT for packets coming from specific MAC addresses. Can anyone give me an example of specifically how I should form this rule? Elijah Chancey NetlinkIP Sysadmin
