Hello. We have a ASA 5520 and we have all kinds of trouble on our ftp connections. FTP servers disconnect immediately when we issue a data connection like "dir" or "get". FTP client is in the inside from a Windows Command line. Windows ftp does not really support passive mode. If we use a perl script, the data transfer will complete. What can we configure the ASA so that active mode is possible? Or, how can we configure the ASA so that there is no port translation will occur? Thanks in advance.
Try adding the FTP inspect to your policy. Here is a link for it.
