Linux proxy-arp does not answers arp requests to the same interface the
request came from. That means that if the request for a published arp came
from eth0, Linux will not send the answer back to eth0, even if you
configured it to do so.
I had this problem some months ago and, to solve it, I had to write my
own proy-arp daemon.
