DHCP works via subnet broadcast - if you are doing DHCP across a router, the 
router needs to have dhcp-relay function turned on.  Otherwise you are stuck.

The filename is set in the main ISC dhcp definition if you are using the 
shipped /etc/cobbler/dhcp.template. Hence it is inherited by individual 
entries. No need to set it individually for each host entry.
