The rule option "bridged" is used as an alias for "layer2" by the ipfw=20
command.=20

Some interesting points written in "PACKET FLOW" in man ipfw and "BUGS" in =
man=20
bridge.

Examples how the layer2 rule option could be used (I have not tested them, =
you=20
can find some more on google):

 ${fwcmd} add pass layer2 mac-type arp 	// allow arp
 ${fwcmd} add skipto 20000 layer2	// goto rules for bridged packets

 ${fwcmd} add [...]			// rules for non-bridged packets
 ${fwcmd} add deny all from any to any	// end of rules for non-bridged pack=
ets

 ${fwcmd} add 20000 [...]		// rules for bridged packets=20
