But there is anything very strange occurring.....I can authenticate on FTP Server....but when I try to get a list (ls or dir or something else.....) simply the server give me a packet on a random port....so my FW blocks!!! Is it right or not? If right, what I have to do on my fw to permit this packet traffic? Thanx, Fabiano Pacheco
