By allowing PF to process the iplog table using DHCPREQUEST packets we end up 
with lots of bogus entries with 90 day leases
(any Apple device basically!!!!).

I have installed the UDP reflector on our production DHCP server and configured 
PF to use only the DHCPACK messages now
and it all it seems to be working in that all our IP/MAC addresses are now 
appearing in the PF database with the correct lease times.

I am now however seeing a lot of these messages (literally 1000's):-

I would add our network is very very busy with well over 7000 clients.

Any ideas on what they may be referring to. I have increased the number of 
'helpers' in the pfqueue.conf file
but they (the messages) still occur in large batches.
