Cisco ASA 9.1 FTP Teardown TCP Connection
Posted on 2014-02-24
We have an internal server trying to download files from an external FTP server. I can connect to the FTP server from the internal server, let us call this server FTP-Client. However, when I try to download a file from the external FTP server, I get this message:
Connection closed by remote host.
I checked the logs on the Cisco ASA firewall, and this is what it shows:
Teardown TCP connection 123348 for outside:external-FTP-server-IP/21 to inside:FTP-Client-IP/32134 duration 0:00:29 bytes 338 TCP Reset-I
Can anyone of you help me solve this problem?
