Yes but the wrong way around! :-/

A tap receives an external arping packet ok (as shown using tcpdump). 
Then does nothing with it.

So, when using arping on some remote host to the local host with the 
taps, what can I hang onto the tap on the local host to listen for an 
arping and send an arping reply back? :-)
