Hi all!
I'm using batman-adv (2014.2.0) on two devices running OpenWrt
(LibreMesh) connected using a third device running a proprietary
firmware in bridge mode (AirOS), this is the topology:

mac3E80 OpenWrt batman----cable----macE3E7 AirOS station----wireless--
--macE434 AP OpenWrt batman
using tcpdump on the OpenWrt devices I can see batman packets flowing:
on mac3E80 I can see:
http://sprunge.us/iePM
while on macE434 I can see:
http://sprunge.us/DIAX
as you can see the problem is that macE434 sees packets from mac3E80
*approaching with the wrong mac address*, the mac address of macE3E7 so
I think it discards the packages when source mac address is different
from mac address specified inside the packet.
Is this only a security check?
How could I get things work?
Thanks,
Ilario
