Yes, I know that. After mapping, I can still not get flows for traffic from
my inner addresses to outside addresseses, because they are not reachable
(offline). So my idea is to reverse the src ip and dst ip so that the
outward traffic (payload) can generate flows on OVS. Is there any way to do
that using tcpreplay?
