I am trying to qualify a PIX-501 router to be used in a new product line.
The problem that I am having is that the PIX is dropping the DHCPDISCOVER relay packets.
The way that our product works is that first we send a regular DHCPDISCOVER message (ethernet broadcast) and then we act as a relay agent to other equipment connected to us.
The PIX is our final DHCP server. The first DHCP packet receives a good answer from the PIX. But any subsequent relay packets sent to the PIX are discarded.
I am attaching samples of both packets as seen in a network monitor.
See included attachment...
Any ideas why the second packet is discarded?
