Hi,

for this to work .1, .2 and .3 would need to rebroadcast the ARP requests. In 
a normal wifi ad-hoc network this will not happen. Also, in a ordinary ethernet 
network no router will rebroadcast ARP requests.

Basically, you can solve this in two different ways:
* You use routing and flood the network with IP addresses using the batman 
daemon.
* You create a bridge over the whole setup using batman advanced (batman-adv 
will handle the ARP rebroadcast).

Marek
