here's a bad idea: clone the mac and IP, put them on the same hub or
switch (assuming it isn't smart enough to somehow try and fix this
brokenness.)

The packets will go to both.

you might even be able to run a proxy or some forwarding firewall like
thing on the 2nd box and forward to the test box, which would help
make sure the test box can never get an answer back to the origin.
