On the PIX I have "ftp mode passive" & "inspect ftp" enabled. I also have an OUTSIDE ACL rules allowing access to the ftp-server which eq ftp & ftp-data. In my efforts to get passive ftp working, I also have a DMZ ACL rule allowing the ftp-server access out which eq ftp & ftp-data (most probably not needed). When I watch the connection logs on my ftp client it does not make a passive connection, I watch the connection being established through the ASDM log entries on the PIX and I can see the session being set-up for what appears to be active ftp only (ports 20&21), I cannot see any high ports being connected either on the PIX or on the connection log of the ftp client. Is there anything more that has to be enabled on the PIX to help establish passive ftp, or should I be looking at the ftp-server? Not sure?
