Criterion in an ACE containing a permit statement Halt further evaluation of the packet against the remaining ACEs in the crypto map set, and evaluate the packet security settings against those in the IKEv1 transform sets or IKEv2 proposals assigned to the crypto map. After matching the security settings to those in a transform set or proposal, the ASA applies the associated IPsec settings. Typically for outbound traffic, this means that it decrypts, authenticates, and routes the packet. Match criterion in an ACE containing a deny statement Interrupt further evaluation of the packet against the remaining ACEs in the crypto map under evaluation, and resume evaluation against the ACEs in the next crypto map, as determined by the next seq-num assigned to it. Fail to match all tested permit ACEs in the crypto map set Route the packet without encrypting it. ACEs containing deny statements filter out outbound traffic that does not require IPsec protection (for example, routing protocol traffic). Therefore, insert initial deny statements to filter outbound traffic that should not be evaluated against permit statements in a crypto ACL. For an inbound, encrypted packet, the security appliance uses the source address and ESP SPI to determine the decryption parameters. After the security appliance decrypts the packet, it compares the inner header of the decrypted packet to the permit ACEs in the ACL associated with the packet SA. If the inner header fails to match the proxy, the security appliance drops the packet. It the inner header matches the
