After several unsuccessful trials and researches :hammerhead with the help of Fido12, a malfunction has been highlighted with the firmware version 15.0

According your ISP's box , no remote access is available if you use the passive mode.

Indeed, the configuration of the FTP server masquerades your public IP address with the firmware version 15.0 and then this option may be conflict with your box if this one is a dynamic masquerading router.

You can detect this with the PASV command in the FTP client's log , for example you will find these lines if you use the passive mode:

Code: Select all

227 Entering Passive Mode ( xxx , xxx, xxx , xxx, 189,29 )

where xxx.xxx.xxx.xxx is your public address and in this example, (189,29) is the port that the server requests the client to use : 48413 (189 * 256 + 29 ) . If the port is not in the range of passive ports of your ftp server there is an issue between your box and the FTP server.

In version 15.1 , an option will be added to enable or disable the " masquerade" option that is usually necessary with the unsophisticated routers.
