problem with proxy usage

Message

I cannot connect filezilla through my proxy.

I have a proxy - sambar port 80 - fully functionnal.
and vsocks - port 1080 - fully functionnal too

I want connect a FTP server, and I would prefer go on it with sambar.

What does I have to configure ? I tried setting "paramètre proxy" and "paramètre proxy FTP", put Ip address and port 1080 in socks 4 setting. I tried to put the address an port 80 in the second connection's option.
nothing.

Is it possible :

I just change the welcome message in the Filezilla server.

How the client recognize the end of welcome message ?

I have sometimes the problem : waiting for welcome message...
but, My filezila client doesn't work, but I have some line in the log.

I think with many try I made, sometime, it's possible to go works.

Can somebody answer my question ? How the client synchronize or detect the end of welcome message ?

Multiline replies from the server (including welcome message) start with the reply code followed immediately by a dash.

The end of the reply is reached if there's another line starting with the same code followed by a space. See example below (FZS default welcome message)

Ok for that, I have rebuild the original welcome message on the server.

The client continue to don't work.

log :

"mysite" is the site I want join
"myproxy" is my job proxy, who connect everybody all the time.

I don't know what is wrong, and I suppose the proxy access client connection wrong. I don't need

I think the client connect to the proxy intead of through the proxy.
I have no trace in the log of any connection. (connection with proxy FTP, no proxy - Socks)

An other configuration :

This one is through an IPCOP firewall.
If filezilla is set with no proxy, all is very well.
If filezilla is set with ANY proxy, nothing append (waiting for connection)
sure, squid is configured well, IE works in this configuration to see the same FTP site, through the IPCOP proxy squid.

Nothing change in passive mode.

Is there any bug in the proxy part ?
