I create ForcePassiveIP and PassivePortRange and using FZ, TC (passiv mode from outside slow at connection, then seems to be ok) or cmd my FTP works fine (activa and passiv). But when I tested my ispconfig 3 ftp conections on: https://ftptest.net/ I recieve this error: Carriage return without line feed received (I recive this error after I create ForcePassiveIP) . I got right ip on pure-ftp service restart. Before (create ForcePassiveIP) I had this error on test: Error: Server returned unroutable private IP address in PASV reply Any help will be appreciated
