[ftp] Filezilla FTP Server Fails to Retrieve Directory Listing

Ok this helped a lot, I couldn't find a fix.

Simply, I already port forwarded the FTP port to my server. (The default is 14147, I'll use this as example)

Go to Edit > General settings, Listening port should be the one your using, in this case 14147.

Then go to Passive Mode Settings, I checked "Use Custom Port", and entered in the Range 50000 - 50100.

Then on your router, port forward 50000 - 50100 to the server IP locally.

IPv4 specific settings I left at default, reconnected my client, and bam now the file listing appears.

Ensure your servers firewall has an inbound rule set to accept 14147, and 50000-50100.

Basically what Evan stated. I can't attest to the security of opening these ports, but this is what finally got my Filezilla client and server to communicate and view files. Hope this helps someone.
