FTP Proxy - Enable this option so that you can specify a SOCKS proxy host address (required) and a SOCKS proxy port number (optional). FTP proxy is an application-level gateway for FTP. It functions between a client and a server, forwarding command and data streams. Beside this basic function, which makes the program helpful on firewall or masqueraders, it offers fixing the FTP server (for example, for connections into a protected LAN) and proxy authentication.
Http Proxy - Use this option to enable an HTTP or SOCKS proxy. After the proxy is enabled, the proxy will be used for all server communications.
