Need assistance setting up ASA to allow passive FTP connection!
I can get the FTP client to connect but it does not pull the directories. I have opened 21 and range of 55536-55566. I had some trouble gettting the range opened and saved. Normally with other small business routers (GUI) I make sure those ports are forwarded and ftp works. Please advise….
Is the ftp inspection killing connection or is it my config?

Hello Jason lest do captures to see what is going on on this connections as the config looks good
You will need to create one capture on the inside interface then one on the outside.
Afterwards download them as a PCAP file and finally upload them to this case.
