Figure 3.27: Configuration of the Internal FTP Proxy
Port reset PASV By default, this check box is activated, so passive FTP
mode is selected. In passive mode, the FTP client asks the server which
ports to use. The client then opens this port for data transfer. If you
deactivate the check box, data transfer takes place in active mode,
which means the client sends a request to the FTP server, which then
opens a port for data transfer to the client.
Same address The check box is activated by default. In this case, the IP ad-
dress to which a request is sent must match the address from which a
reply comes.
Magic User: If you activate this check box, the selected destination FTP
server is given the user name user@host:port. This may then ap-
pear as follows:
> ftp [e-mail]:21
Magic Char: The Magic Char character is set to ‘%’ by default. If the op-
tion ‘Magic User’ is activated, any character can be chosen.
