These error messages are shown as a result of a prior bug fix that resulted in a NAT behavior change. In ASA software version 8.4(4) and 8.6(1.6), the NAT configuration restrictions changed such that you cannot configure a NAT line that would overlap with IP addresses used by the failover interfaces on the ASA (that is, if failov»reddit.comCiscocommentsWant to join?
