normal iptables NAT won't do in this case, the gateway machine is
gonna ask the MAC address of the remote Ad-Hoc device through eth0,
which won't get an anwser at all, that is why I need a damn bridge.
But finally I found the solution, layer 3 ARP bridge: parprouted.
I just do not understand why a 2009 linux box won't do a 2001 win XP
job (wired - wireless bridge).
