The ping going out goes to the correct route but a ping reply from the other machine goes to the default route. >From my setup, and a dump of 2 packets that show that MAC dst. On the echo req it has the correct dst, but on the echo reply the dst is the default route. The output is from 2 seperate pings and I cut down on the output.
