I've sniffed the network (although not in a problematic case) and I sometimes I'm able to see the DHCP NACK message, but then the client correctly asks for the new lease and receives the subsequent ACK. I'll toy with the lease time option (the default lease time is a year per default). I'll see if that helps. thanks, Michele
