Hi

I don't think this is DHCP
21:54:45: %SEC-6-IPACCESSLOGP: list 103 permitted udp 0.0.0.0(0) ->
255.255.255.255(0), 1349 packet

From this
L3-src = 0.0.0.0
L3-dest = 255.255.255.255
l4-src = 0
l4-dest = 0
incoming PPS = 1350 pkts / 4 minutes

For DHCP l4-dest should be 67/68

Something else is wrong ? Do you have sniffer on LAN ? Can you capture the
packet ?

thanks
deepesh
