DHCP / Cisco IPhelper - Problem to get valid IP-Adresses

[Tim Peiffer]

You are missing a critical element.. what is the configuration of the 
subnet..  do you multinet (aka secondary)?
The 'ip helper-address' in the cisco's only cause the router to edit the 
giaddr field of the DHCP packet, tear off the IP broadcast headers and 
then resend them as unicast to the 'helper-address' as a destination.
