This is debug ip udp ,and debug arp, trace.

"creating incomplete entry for IP address"
"IP ARP throttled out the ARP Request"

For some reason, BootP works fine if I have arp entry already in the router,
but if arp clear out or its brand new PC, it does not work. I mean get a IP
address.

Above is the debug

I have

Int fa 0/0
Ip address 192.187.18.1 255.255.255.0
Ip direct-broadcast

Int fa 0/1
Ip address 192.187.0.65 255.255.255.0
Ip helper-address 192.187.18.9
Ip direct-broadcast

Switches have portfast enabled.

Boot server 192.187.18.9
PC 192.187.0.82

Help...
