The physical box has only one network interface? If there are multiple
nw interfaces, make sure you are testing netboot with the same one you
tested with dhclient.
If you execute dhclient without specifying -s parameter (server IP
address), it also works?
Doing that will broadcast the DHCP request and that is what will be done
during netboot.
