It seems to be the one remaining noise on the firewall. It is about DHCP, and a broadcast, that I know. But I don't know if I should accept, reject, drop, nor how to accept them, or silence them.
It's a dhcp client looking for a dhcp server - what to do with it is up to you, depends on your context.
Oh, another strange one. But just one packet.
