>Description:
In ipfw(8) we read:
# packets from ether_demux or bdg_forward
ipfw add 10 skipto 1000 all from any to any layer2 in
..skipped...
(yes, at the moment there is no way to differentiate between ether_demux and bdg_forward).
But in RULE OPTIONS (MATCH PATTERNS) section:
bridged Matches only bridged packets.
..
layer2 Matches only layer2 packets, i.e. those passed to ipfw from ether_demux() and ether_output_frame().
After reading /usr/src/sbin/ipfw2.c I understood that layer2 and bridged are aliases. To make man page clearer it should be reflected in it.
