I will take a stab

Log entry 1 is comming in on  eth0, and machine 192.168.1.4 is making a
bootp/dhcp request, which you machine is reject.

Log entry 1 is going out on eth0 from 192.168.1.2 which is 
a reply to the boot/DHCP request from before.

Note from memory the dchp server attachs to the interface in such a way
that netfilter can't stop it.

Why this happens when you loose conection not sure.
