Test script were ns3 fails

Hi,

I am using ns3.2.1.RC2 and I cant setup a multi-hop network as follows:

TOPOLOGY:

     WIRED CSMA             WIRELESS CHANNEL
   ______________
   O            O  ))          (( O ))           (( O
   N3           N0                N1                N2  

Here N1 hears packets from N2 and N0 but N2 can not communicate directly with
N0. However, when I run it, N2 sends his ARP but N1 does not forward it to N0
and therefore it is not able to communicate. I am using Global Routing and
running OLSR on the wireless network. 

P.S. Is there anyway to have a GOD mode ARP in which everybody knows everybody
else's MAC address? If not, can you guys add this feature? Its probably easy to
do but will take me longer to do than you guys.

Thanks!
