the issue maybe related to the acl, "access-list outside_access_in permit tcp any eq ftp any eq ftp"

the reason being that the source port will be a random port (usually >1023).

modify the acl without specifying the source port.

e.g.

access-list outside_access_in permit tcp any host xx.xx.62.98 eq ftp

Thanks a lot for your support. The reason is this.

I change it and running without any problem.

Thanks again,

Alex.
