[Click] Issue with Intra-node Click Packets dropped by Kernel

[dmoore7@nd.edu]

Update:

After further testing, it appears that if I change the source of the incoming
PING to a non-local IP (StoreIPAddress(<IP of N2>, src), for example), that the
packet is NOT dropped, and a PING reply is generated, although it is sent to the
wrong node (ie. to the node who's address I claimed the packet came from).  This
is without any modification to the actual MAC address, which remains correct
after I change the IP address.

Thus it appears that Linux ignores packets destined for itself (by IP address)
if the source is a device it controls itself.  I am not yet sure how I will
work around this, as sending packets to myself (from one spoofed device to
another) is essential.

Again, any ideas and input are appreciated.
Thanks,
