N0 and N1 are wired nodes. In the communication BS1 -> N0 the packets 
stay in loop between BS1 and N1, never arriving at N0.

In the communication between N0->BS1 the packets arrive at BS1 but the 
ack's stay in loop between BS1 and N1, never arriving at N0. :(

The simulation already contained the next two lines with the above results:

$BS0 base-station [AddrParams addr2id [$BS1 node-addr]]
$BS1 base-station [AddrParams addr2id [$BS0 node-addr]]

Somebody have experience with this situation, please?
