Yes, but i would like to run only one daemon.

I think is possible to change option to the DHCP when the client request an address, with the dhcp-server-identifier option, but how ?

Thank you for your help

With some restrictions I think you can make ISC DHCP do it - but you need to recompile it with different options set (dunno what, but they prevent it directly dealing with packets on the interface) AND all requests must come from remote networks via a relay agent set to unicast the requests to the server.
