Let me guess, you're using Ghost? Same problem here. We did a packet trace,
and the CAS answers the DOS-based client but the client doesn't pay anby
attention.

Subject: BOOTP in Real-IP Gateway with CAS as DHCP server

Hello - 
We're running into a problem trying to get our public workstations to
re-image. Packet captures show the workstation making a discover, the CAS
DHCP server making an offer, but nothing past there, no Request of ACK
packet is ever created. We're believing this to be because the source IP of
the offer is from the untrusted IP of the CAS. When we insert another DHCP
server onto the subnet, the process works just fine.

We are currently building another CAS pair to test as a DHCP relay agent,
but want to know if anyone has BOOTP working through the CAS with the CAS
working as the DHCP server.

We are running 4.1.3 on our NAC devices, and I have enabled BOOTP in the
DHCP server as a global option.
