On the log, the line 227, indicate that for the 5 test I made today: I check the logs on the server and each time it's look like the server not want use the port I want, but the port the server want ?!? When I try to connect, is not possible (from outside world) to list and transfert file. I opening my router (synology 2600ac) I open the port 25410, and I add the trigger port 25410 for opening the range : 25411-25511 The port use is : 25410, the range of the passive port is 25411-25511 Inside, I use fille zilla application and voila ! is because is not possible to use them with the outside world of my network. Let me know if I'm wrong, I'm just reporting as to what seemed to have worked for me, and assumptions I've made based on those experiences.I try to use FileZilla server for a moment, now I have the time to configure them and debug them, why debug. I'm not sure what other test conditions such as downloading and uploading simultaneously would do, but I believe the most reliable settings would likely be the following: Edit > Settings > Transfers > Concurrent transfers > My understanding of these settings is that the above configuration should resolve the issue as others have stated, but it's possible there is a bug or miscommunication of how this feature performs in the version I am using. Limit for concurrent uploads: 0 (no limit)

Limit for concurrent downloads: 0 (no limit) My previous settings were: Edit > Settings > Transfers > Concurrent transfers > I found that only setting the Maximum simultaneous transfers to 8 did not resolve the issue when uploading files. This is how I ended up resolving the issue: Edit > Settings > Transfers > Concurrent transfers >

I know this is an old thread, but I thought I would provide the following update based on a more recent version of FileZilla.
