we are running an ASA firewallsystem and getting
Teardown TCP connection 56410XXX for outside:XX.XX.XX.XX/1521 to inside_demo003:XX.XX.XX.XX/1199 duration 0:00:00 bytes 3334 Flow closed by inspection
Anyone can tell me, the
"closed by inspection" message
is sent by the ASA for what kind of firewall discrepancy ?
I checked the cisco docs on here, but I just found some shallow info on this.
Maybe there is a larger style error table somewhere that I did not find yet.
It also would be great, if someone could guide me a little bit more in the direction for what valid reasons a packet can be dropped in the above case. (packet inspection) Maybe there is a matrix for it.
Thx in advance
