106016: Deny IP spoof on interface
Cisco ASA is a security device that provides the combined capabilities of a firewall, an antivirus, and an intrusion prevention system. It also facilitates virtual private network (VPN) connections. It helps to detect threats and stop attacks before they spread through the network.
Message: %ASA-2-106016: Deny IP spoof from (IP_address ) to IP_address on interface interface_name.
Event 106016 is generated when a packet with destination IP address as 0.0.0.0 or an invalid source IP address is discarded. The address is considered invalid if it is from a loopback network or broadcast address.
How could you resolve this situation?
Determine if the IP address belongs to an external user trying to compromise the protected network. Check for misconfigured clients.
