Problem using FTP through proxy

[leonep@micso.net]

Hi ,
I have my connection behind a firewall and i must use proxy for ftp . I use putty and works well for surf the web. i use a SOCKS5 .
i have setup filezilla to use proxy like firefox , it connect correctly but cannot browse folders and return an error EPSV 500 .
What kind of error is this ?
Of course the final ftp (centos+pure-ftpd) it's production server and works good with another PC / connection.
i hope someone can help me to understand my problem...
thanks

server is good because with no proxy connection it works good and accept to work

it seems that proftpd accept to work with SOCKS5 connection and pure-ftpd in HTTP Proxy
