I have issue accessing FTP links through my Cisco Firepower ASA 5545. Although FTP inspection is enabled on my Firewall, but still I can not access any public ftp links.
Bellow error I get on my ASA logs:
4|May 08 2017|11:12:32|507003|192.168.2.6|52771|220.127.116.11|21|tcp flow from inside:192.168.2.6/52771 to outside:18.104.22.168/21 terminated by inspection engine, reason - disconnected, dropped packet.
Is it enabled on the global policy or interface policy. If interface one, make sure that your service policy is assign to the right interface
