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