Hello. I have ISPConfig, the latest version installed on Ubuntu Server 18.04 TLS and can't get pure FTPD working. I've read a lot of topics, and here is what I did so far: 1. In my router, I have enabled forwarding for ports 21 and 22 to my server private IP address (192.168.0.108) 2. I have set "ForcePassiveIP" in /etc/pure-ftpd/conf set to my external IP (85.187.xx.xx) - it is a static IP bind to my router MAC address 3. I have set "PassivePortRange" in /etc/pure-ftpd/conf "30000 50000" 4. I have created a file in /etc/ufw/applications.d called "pure-ftpd" with the following content: Code: [pure-ftpd-mysql] title=FTP server (cp.shhservice.com-FTP) description=Simple FTP and FTPS Server ports=21,30000:50000/tcp and then allowed the rule. 5. With "ufw status" I can see the rule is added and "ALLOWED" When trying to connect via FileZilla (with my server domain, my site domain or via IP, response is: Code: Status: Resolving address of cp.shhservice.com Status: Connecting to 85.187.xx.xx:21... Status: Connection established, waiting for welcome message... Status: Initializing TLS... Status: Verifying certificate... Status: TLS connection established. Status: Logged in Status: Retrieving directory listing... Command: PWD Response: 257 "/" is your current location Command: TYPE I Response: 200 TYPE is now 8-bit binary Command: PASV Response: 227 Entering Passive Mode (85,187,xx,xx,168,191) Command: MLSD Error: The data connection could not be established: ECONNREFUSED - Connection refused by server Will be glad if someone can help. Best regards.
