Sounds to me like this "filtering" of dhcp requests is going down in
the kernel space. Check /proc/sys/net for options to the kernel that
may need turning on/off. As a side note (might help in this case), my
kernel echo's "martian" packets (ie: packets which should not be sent to
a particular interface, but end up there). dhcp requests always
generate martian logs on my network. Maybe you have pf set-up to drop
these martian, like in this pesuedo example
if (in-iface == eth0) && (src/dst ip != 192.168.1.1) ; then
drop
fi
Maybe you just have some strict settings turned on in /proc/sys that
drop broadcast packets, or martian packets.
