Hi Massimo, you are using one of the oldest Labs releases (from January 2015). The current release is 160919.

I recommend that you upgrade your project to that version. You may also upgrade the kernel (to 9.0.0) but that isn’t necessary.

But as I haven’t seen malformed DHCP packets yet, could you attach a small PCAP file that shows some of those packets?
You can filter DHCP packets with “udp.port==67”
