The client is connecting to a server behind an NAT router, whose IP address facing us is also a private address, as illustrated below.

+-----------+   +-------------|------+   +--------------+
| my client |   |    NAT router      |   | their server |
| 172.x.x.x +---+ 192.168.x.x | 10.x +---+   10.x.x.x   |

I left the setting for "Connection / FTP / Passive mode" by default, to "Use the server's external IP address instead". However, it did not work for me.

The attached log file 20220601-1751.log shows at lines 82 and 161 that the server replied with its private address, and a netstat command on the client at the moment showed it was actually trying to connect to exactly the server's private address.

I noticed a trace message in the log file, i.e.

Destination IP of data connection does not match peer IP of control connection. Not binding source address of data connection.

Having searched this message in the source code, I arrived at function CTransferSocket :: SetupPassiveTransfer, and found that its host argument seemed to be assigned in the function CFtpRawTransferOpData :: ParsePasvResponse.

Inside ParsePasvResponse, the condition for assigning the peerIP from the control socket to the host_ of the passive data connection is an un-routable data peer address as well as a routable control peer address. Unfortunately, with all un-routable, internal addresses for both data and control, my scenario effectively bypasses this mechanism.

At the end of the ParsePasvResponse function, I noticed that I can instruct the client to always use server address by setting the option OPTION_PASVREPLYFALLBACKMODE to 2, which is set by an option named Pasv reply fallback mode, stored in %appdata%\FileZilla\filezilla.xml. I wonder the intention on omitting this option in the settings UI, although it indeed provides a workaround for my situation in the current version.

Hello im using hp laptop and my phone as wlan internet provider. SOmetimes my hp will lose WLAN connection and retries it. In this behaviour Filezilla:

Komento: cd "/home/dh_g2amwh/tfj.iware.fi/public/packages/ext-theme-classic/resources/images/tree" Virhe: Tiedostonsiirto epäonnistui "File transfer failed" Tila: Yhdistetään kohteeseen jerroi.dreamhosters.com... "Try again" Virhe: Yhteyden aikakatkaistu, koska yhteys oli toimimattomana 20 sekuntia "Connection waited 20s" Virhe: Tiedostonsiirto epäonnistui "File transfer failed"

So FileZilla will sometimes freeze on this. Now filezilla wont progress anything, wont connect new connection to new tab onlything that helps is to restart Filezilla and start upload of 15k files again.

FileZilla wont keep connection alive somehow and results frozen behaviour. Unstead of try connect you could use somekind of is internet alive loop that waits connection to internet then tries continue. But the connector will break filezilla as it is for now. And very fustruation as I have 15k files for my app and if it breaks somewhere in 5k to go I have to try send 15k again just to filezilla check if to overjump files wich will take a lot of time again.

And since FileZilla dont have filetransfer saving or current session saver script it wont remember filetransfer on restart which is a bit annoying.

Hi!

I updated to version 3.59.0 in Windows 11, but at various times an error occurs that says that more than 20 simultaneous connections are not allowed and it is disconnected. Even changing the value in the settings. In previous versions this problem does not happen. I went back to the previous version 3.57.0 and it works normally.

Thanks!
