While troubleshooting on a problem related to communication problem between two systems with a firewall in between , it was observed that there were no connections seen in connection table ( as seen usually ) , although regular builtup & tear down connection were seen appearing in log.
The file transfer is not working for some reason. ASA shows the connection of teardown and builtup for this but nothing appears in the sh conn table.
In such a scenario does it mean that destination system isnt responding to the query and thus even though connection is allowed thru the ASA ( with rules in place) , connection table wont show it unless it is successful.
Please help me understand this and any other way to troubleshoot such problems.
Thanks in advance!
If there are no connections showing on the ASA most likely traffic is not making its way through.
Are you using NAT, do you have ACLs restricting traffic?
