Hey guys.

Got a DHCP Problem

1. Discover comes into 1811

*Aug 24 15:01:11.919: DHCPD: Sending notification of DISCOVER:
*Aug 24 15:01:11.919:   DHCPD: htype 1 chaddr 0004.e245.f1a1
*Aug 24 15:01:11.919:   DHCPD: remote id 020a0000d238e801060000c8
*Aug 24 15:01:11.919:   DHCPD: circuit id 00000000

2. Linux box gets it, and makes an offer

Aug 25 01:01:30 newton dhcpd: DHCPDISCOVER from 00:04:e2:45:f1:a1 via
x.x.232.1
Aug 25 01:01:30 newton dhcpd: DHCPOFFER on x.x.232.50 to 00:04:e2:45:f1:a1
via x.x.232.1

And.. That's it.  Cisco 1811 doesn't see the offer and relay it back to the
DHCP client.

Just keeps trying over and over and over again.

Cisco config..

version 12.4
ip dhcp relay information option
ip dhcp relay information policy keep
ip dhcp relay information trust-all
interface Vlan200
 ip address x.x.232.1 255.255.254.0
 ip helper-address x.x.224.130

Anything I am missing?

Debugging not showing anything else but the DISCOVERS..

1811#show debugging 
DHCP server event debugging is on.
DHCP server linkage debugging is on.
DHCP server class debugging is on.

Thanks all to those who help.. And for helping previously with my initial
email last week.
