Short version: don't bother

I'm pretty sure EC2 only allows one IP address, so you can't arbitrarily
use another one, even on the same segment.

In your case however, I'd examine the output of "netstat -nr" and "brctl
show". The ping packets should've been sent from 10.0.3.1 (the bridge), so
it's odd that 10.0.67.72 complains about "Destination Host Unreachable". At
first glance that indicates routing or interface setup error on your bridge.
