Duhhhhh! (as I smack my head) I should have realized that :)
Thanks for the dope slap!

Well, when I ran tcpdump on my interfaces I was looking for both
src/dst packets of the host I was on. So, grep'ing for icmp packets,
even though connected to a switch, if my echo replies were going out
a different interface than the one the request was coming in on, I
should have seen it.

It may look like I'm just sitting here doing nothing,
but I'm really actively waiting for all my problems to go away.
If you're not having fun, you're not doing it right!
