I appear to have a NAT problem with ASA build 7.2(3). I cannot SSH or SSL (with CSM) through the inside interface to the outside interface i.e. I want to manage the device on its external interface. I want to manage the device on its external interface as I have a second CSM server at a remote site. I receive the following errors when I SSH from an internal host to the external interface:
%ASA-6-302013: Built inbound TCP connection 14343 for MANAGEMENT:x.x.x.x/3265 (x.x.x.x/3265) to NP Identity Ifc:y.y.y.y/22 (y.y.y.y/22)
%ASA-6-302014: Teardown TCP connection 14343 for MANAGEMENT:x.x.x.x/3265 to NP Identity Ifc:y.y.y.y/22 duration 0:00:00 bytes 0 TCP Reset-I
Both the external and internal interface are logical interfaces on the same physical. Could this be the problem?
