I almost had a trombo unti I discover my airport express do not allow me to use filezilla or cyberduck to conect to my server. I just discovered it was an airport express issue when I connected to the internet provider's modem's wifi. this is crazy. why apple did that?
OS X Yosemite (10.10)
There is an entire discussion here:
Opening Ports on AE to allow for outside FTP access to NAS
Note that FTP is a very old and extremely insecure protocol and therefore should really be abandoned. If you configure your server to use SSH and SFTP instead, you will not only be far more secure, but you will no longer have a problem with the odd way the FTP requires two ports that does not work well through NAT firewalls. By using SSH and SFTP you can also configure public/private keys on your Mac and server that Filezilla, Cyberduck, and Transmit can use for passwordless transfers.
I reseted my airport and now ftp is working ok, I guess a nat problem
why aiport express block port 21 to use ftp server?
