Message CodeASA-4-402116
SeverityWarning
DescriptionIPSEC: Received an protocol packet (SPI=spi, sequence number=seq_num) from remote_IP (username) to local_IP. The decapsulated inner packet doesn’t match the negotiated policy in the SA. The packet specifies its destination as pkt_daddr, its source as pkt_saddr, and its protocol as pkt_prot. The SA specifies its local proxy as id_daddr/id_dmask/id_dprot/id_dport and its remote proxy as id_saddr/id_smask/id_sprot/id_sport.
ExplanationThis message is displayed when a decapsulated IPSec packet does not match the negotiated identity. The peer is sending other traffic through this security association. It may be caused by a security association selection error by the peer, or it may be part of an attack. This message is rate limited to no more than one message every five seconds.
