Okay, that's a good reason why you can't use the bootp mode of your DHCP
server.

I still find it hard to believe that your modem users have MAC addresses -
all dialup systems I have seen use PPP Point to Point Protocol and there is
no MAC address identifying the remote system.
However, I could be wrong, and the way to check this is with the LOG rule I
already recommended, so you can see the MAC address and source / destination
IP addresses of the packets coming in to your netfilter machine.
