inbound to an interface: before. outbound from an interface: after. promiscuous mode apps normally attach at the BPF layer which is below where a layer 3 filter like PF hooks into the stack. so as a packet go up the stack it hits BPF, then layer 3 filter. as a packet goes down the stack on the way out, it hits layer 3 filter then BPF. -j -- "If I wanted smoke blown up my ass, I'd be at home with a pack of cigarettes and a short length of hose." --The Simpsons
