Just installed a fresh copy of Ubuntu 20 and ISPConfig. All works great except the FTP server. My server in behind a NAT and, yes, I did set the passive ports and force externel ip in the PureFTPd config folder, restarded purefpd-mysql and forwarded in the router the range of ports (60000 - 65535) TCP The forward on the router works (As DNS, HTTP, HTTPS, SSH, etc works with no problem) I can connect via LAN to the FTP server (if I disable force IP) but cannot connect from outsite if the network (WAN) FileZilla client outputs this: 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 (X,X,X,X,237,233) Command: MLSD Response: 150 Accepted data connection Error: Connection timed out after 20 seconds of inactivity Error: Failed to retrieve directory listing I am pretty sure it's not a NAT/Firewall issue, Thank you!
Is the same set in your server via ISPConfig UI? I asked because I think default passive ports set by ISPConfig may be different.
Yes, I modified the exact ports in: - /etc/pure-ftpd/conf/PassivePortRange - forwarded that range in the router - checked in firewall is disabled in ISPConfig (yes) - checked ufw if disabled in ubuntu (yes)
are the 60000-65535 ports completely open? don't know what nat/router your using.. possibly traffic on those ports needs to be configured as establised/related to the traffic on port 20.
