Actually, in order to make this work at all you need a BOOTP relay
agent - just forwarding broadcasts won't work.  If you have Cisco
routers, I think that you can get a built-in bootp relay agent.
Probably other router manufacturers support this as well, but I don't
have any information about that.  If your routers do not support BOOTP
relay, you will probably have to install BOOTP relay agents on servers
on each of your subnets.
