DHCP filter? easy filter rule?

elliotf
I have the following:
  ASL: eth0 - 10.0.1.1/24
  ASL: eth2 - 10.0.0.1/24
I have a linux box set up with:
  DHCPD: eth0 - 10.0.1.68/24
  DHCPD: eth1 - 10.0.0.68/24

I'm trying to do dhcp on my network, but ASL seems to grab the broadcast packets and reject them.  I see the violations in the live ipfilter, and have tried to make a filter rule allowing that traffic through, but I can't seem to get the source/dest correct.  How should I define the networks/hosts I use in the source/dest of the filter rule?

follows is the live filter log:
16:43:37 0.0.0.0 68 -> 255.255.255.255 67 UDP

    Astaro is a router so the broadcast packets won't go anywhere anyhow.

    Astaro is correctly dropping the broadcast packets. However as broadcasts they will travel to all other devices on each subnet including Astaro. So assuming that each eth0 is plugged into the same broadcast domain / ntwork segment then any device on that segment will get DHCP from the linux box. Ditto for eth1
