  I am seeing a lot of

Dropped by firewall: IN=wlan0 OUT= 
MAC=ff:ff:ff:ff:ff:ff:60:fb:42:d1:69:71:08:00 SRC=0.0.0.0 
DST=255.255.255.255 LEN=328 TOS=0x00 PREC=0x00 TTL=255 ID=25801 
PROTO=UDP SPT=68 DPT=67 LEN=308


How can I know who is sending it to my machine if the source IP is all 
zeros?
I have no idea if it is coming from the lan or from the wan?

60:fb:42:d1:69:71 is. If it's wired, you can track down its location.
