Or slightly more convoluted, you could run dhcrelay on a machine that
has interfaces on both the subnet serving dhcp and the one where you
want it to be forwarded. Not sure it would help in this scenario but
it works where the dhcp server is on some other machine. You still
need the subnet declaration in the dhcp server for the forwarded
subnet.
