Hi I've uncovered a problem with the latest pix 515 firmware (asa-8.0.4) which didn't exist in 8.0.3. The dhcprelay function no longer works in some circumstances. Specifically, I can no longer do automated linux client installs over the network (FAI). The initial dhcp at pxeboot time works fine, but the later dhcp operation after kernel boot fails.
The client sends a DHCP Request and this gets relayed to the server without problems, but the returned DHCP Ack is not forwarded back to the client. Turning on debug dhcprelay error etc gives... DHCPRA: relay binding created for client 001d.09fa.6f13. DHCPD: setting giaddr to 192.168.63.1. dhcpd_forward_request: request from 001d.09fa.6f13 forwarded to shadowcat.

Does anybody know what could cause the "DHCPRA: Can't Create binding" error?
