Proxy Server Settings

 

The following proxy server types may be selected:

 

DefaultConnection is made my first logging onto the proxy server and then logging onto the FTP server using separate sets of USER/PASS commands.
FTPOPENConnection is made through FTP transparent proxy server using OPEN command.
FTPSITEConnection is made through FTP transparent proxy server using SITE command.
FTPUSERConnection is made through FTP transparent proxy server using USER joe@server command.
Simple RelaySee below.
SOCKS4Connection is made through SOCKS4 proxy firewall.
SOCKS4aConnection is made through SOCKS4a proxy firewall.
SOCKS5Connection is made through SOCKS5 proxy firewall.
Web StandardTypical proxy using the web CONNECT command. (Example: MicroSoft ISA or TMG servers.)

 

The most common proxy servers types are FTPUSER, SOCKS4, SOCKS4a, and SOCKS5.

 

FTPOPEN, FTPSITE, and FTPUSER are available only for FTP connections since they initiate a regular FTP connection and expect to connect to a 'FTP like' proxy server like what is expected configured for Default. Then, instead of sending, for example, 'USER joe', Robo-FTP sends instead 'USER [email protected]' so that proxy can relay connection to appropriate destination. In the same way, instead of 'USER [email protected]', Robo-FTP sends either 'OPEN real.ftp.server' or 'SITE real.ftp.server', depending on the Proxy Server Type selected.

 

A “Simple Relay” is not a real proxy but rather a ‘pipe’ or ‘redirector’ that listens on a predefined port. When a client connects to this port, a predefined destination server redirects all traffic between the client and the remote FTP server.
