:) no problemo.
It is going to go through a major rewrite after the paper goes out,
but once thats done it shoudl work better, faster, and have fewer
idiosyncracies. plain old forwarding is its default behavior (it puts the
ethernet frames on the other side of the box back onto the wire with the
original ehternet headers, so you see the original source's mac address in
the packet, for example, arps work through it, etc) .. ill post about it
once it is done.
