Hey guys,

I'm still working on my WMN test case and I found this other bug. Before I had
only one way traffic from N2 to N3 using the OnOff application, which worked
thanks to you guys. Now I am using UdpEcho (leave #define COUNTED_PACKETS
uncommented). Running the UdpEcho application, the packets make it to the
destination N4 (172.16.0.1), but for some reason, N4 can not echo the packet
back to N3. Looking at the pcap file, it seems that N4 is asking for the MAC
address of 192.168.0.1 (the gateway N0 on Wifi interface) and it should be
asking for 172.16.0.2 (the gateway N0 on CSMA interface).

Thanks,
