Does the inspection on Cisco PIX or ASA os (7/8) support the FTP extended passive mode


http://en.wikipedia.org/wiki/Ftp


"In extended passive mode, the FTP server operates exactly the same as passive mode, however it only transmits the port number (not broken into high and low bytes) and the client is to assume that it connects to the same IP address that was originally connected to. Extended passive mode was added by RFC 2428 in September 1998."


Thanks in advance.

match protocol ftp

inspect


Had to disable EPRT and EPSV on the server, but it's not good idea, all new ftp clients tend to prefer them.
