i am trying to connect to an FTP server which is placed at outside (internet) with a public IP. firewall is able to ping FTP public IP, but my system placed at inside interface of my firewall with gateway of inside ip of firewall unable to communicate with FTP server.The moment i try to connect with FTP it just establish connection logged in and disconnect when retrieving directory. At the same time my PC without passing through firewall with another gateway is successfully logged upload and downloading file.
ASA setting is
