I actually tried once to get DHCP to broadcast across two subnets with
no success (I allowed the ports to be forwarded, didn't block 0.0.0.0 or
255.255.255.255, etc.). Of course DHCP uses 0.0.0.0 and 255.255.255.255
so that may be a special case. But usually broadcast addresses are
defined within a subnet (like 10.0.0.255) and so I would think they
wouldn't be routed outside the subnet by design.

Just my thoughts - or maybe I misunderstood this part of the issue.
