Do you have a dhcp server on every subnet? Normally dhcp requests are not
forwarded by routers so you can not reach the dhcp server on another subnet.
You don't want that anyway because you would get the wrong settings. So get
a dhcp server on every subnet and beside the ip number also configure it to
set the default gateway,netmask and dns servers.
