I found the reason of my Problem: the virtual machines can't write the ARP table ¡¡¿?!!
When I manually use the command: arp -s 192.168.XXX.XX 00:09:XX:XX:XX:XX I can reach the gateway I can't reach anything from my net segment but i can reach Internet (Double ¡¡¿?!!) For the moment I wrote a script, but is awful to do this. Any idea ?
