Default Transfert failed - Unable to change data channel protection to clear

Hi,

So, first of all, basic informations :

FlashFXP 4.4.4 (build 2046) . Unregistered (trial version, planning on buying if it works )
OS : Windows 7 64 bits
FTP 1 : Dedicated server, FTP 2 : SYnology NAS behind a Freebox V6 (french ISP), W7 client : behind a arkoon firewall (or Freebox v6, depending on where I try to transfert the files)
W7 client runs a trend micro client/server antivirus (the other one has avast and the windows firewall)
Connection : FTP 1 : symetric opical fibre, FTP 2 : ADSL 10 mbps, W7 client : ADSL 10 mbps (or 5)

FTP 1 running on Debian 7 with ProFTPD, standalone mod (with allowforeignaddress on)
FTP 2 running on a synology NAS, FXP enabled and passive and FTP port rerouted through the Freebox

So, my issue is the following :

I'm unable to perform a file transfer.
I successfully connect the 2 FTP, but when it comes to tranfer the files, it doesn't work, though directory are created anyway.

Here is the log (sorry, i set language to english, but some of it is in french. If you can translate, just ask )
