In BSD you need to have the sysctl variable net.link.ether.ipfw set to 1 for layer 2 checks in IPFW. I didn't see an equivalent sysctl variable in OS X. 

sysctl -a | grep net\.inet\.ip\.fw\.


and that tells us?

This isn't BSD. 

It tells us the above.

I think we know that. The original poster was pointing out that he did not find a way to enable filtering at layer 2.

No, he found that how he'd enable this is BSD didn't work under Darwin. He'd have to enable ipfw using the sysctl values that Darwin uses. The above prints those and he can check to see if he's got ipfw enabled from there.
