has anyone experience with proxying SFTP protocol throw squid ?

Client (filezilla) is set to passive mode, ftp control channel works, but
I cannot receive any data.
Squid has configured ports 1024-65535 to allow CONNECT (one from these
ports is randomly used for data transfer over sftp protocol).

Thank's for any idea, Petr linke
