This message is generated when a packet arrives at the security appliance interface that has a destination IP address of 0.0.0.0 and a destination MAC address of the security appliance interface. In addition, this message is generated when the security appliance discarded a packet with an invalid source address, which can include one of the following or some other invalid address:
Loopback network (127.0.0.0)
Broadcast (limited, net-directed, subnet-directed, and all-subnets-directed)
The destination host (land.c)
In order to further enhance spoof packet detection, use the icmp command to configure the security appliance to discard packets with source addresses belonging to the internal network. This is because the access-list command has been deprecated and is no longer guaranteed to work correctly.
*Recommended Action: Determine if an external user is trying to compromise the protected network. Check for misconfigured clients.
