Windows – 425 Can’t open data connection for transfer of “/”

I'm trying to solve this error searching the web, without any success.

The error is:

425 Can't open data connection for transfer of "/"

My software:

• Windows server 2013 and last filezilla server

My topology:

• Server wired to router – Router with a dynamic IP from ISP, dynamic dns updated.

My settings:

• PASV mode with ports 51000-61000
• Retrieve external ip with http://ip.filezilla-project.org/ip.php
• Enabled FTP over TLS with port 990

Where I opened my ports

• router: local and public 21, local 51000 public 51000-61000, local and public 990 (ALL tcp)
• Windows Firewall: both directions, ports 21, 51000-61000, 990.

On my lan it works perfectly. I think there's something wrong with router port forwarding configuration. Here it is.

Is there something I'm doing wrong?

I add a log of my ftp server:

I add the ftp server configuration screens too just in case.
