My goal with L2 is to have victim frames coming to my machine, view the
packets (ie. tcpdump, etc), but have the frames sent back out to the real
gateway to avoid a DoS situation against the victim.  L3 does this for you
via IP forwarding, L2 is another matter.

True, bouncing the packets back out is going to be different.  You could
probably write your own tool for injecting the packets you receive back
onto the wire with a different MAC, or perhaps the mangle table in
ebtables can do that for you.

good luck,
tim
