    Hello Guys,

    I'm having some troubles with encrypted FTP connections. As i could 
imagine, conntrack_ftp and nat_ftp are not being able of recognizing the 
correct ports to open because the connection is encrypted and the PASV 
information is not seen by the modules.

    I dont think so ..... but is there any way of working around this ??

Use unencrypted ftp (which is insecure and not recommended) or forget 
conntrack for this because encrypted channels cannot be on the fly 
decrypted without the keys used for encryption.
