Unless i misunderstood:
He seems to be trying to do a loopback test from one of his interfaces to
the network and back on another of his interfaces.

This would probably cause a broadcast storm if you are doing a loopback
Actually now that i think about it, you could probably modify ping
to do setsockopt(fd,....,SO_DONTROUTE,...) and send it out on a specific
interface. Dont know if it would work.

Try that SO_DONTROUTE and see if solves your problem; you probably have to
bind the socket to a specific device as well;
For all that trouble, i would suggest you may just as well write a sock
packet based app.
