Hi Eric,

The problem lies in routing NAT'ed traffic back to it's respective
device. If the devices have the same IP address there cannot be an
intelligent routing decision made. Netfilter does not support forcing a
packet to be sent to a specific device. Packets must be routed to
devices based up routing decisions.


I would suggest setting up a router for each 10.0.0.0/8 network to
properly route traffic.
