+Long: ftp-port
+Arg: <address>
+Help: Use PORT instead of PASV
+Short: P
+Protocols: FTP
+See-also: ftp-pasv disable-eprt
+---
+Reverses the default initiator/listener roles when connecting with FTP. This
+option makes curl use active mode. curl then tells the server to connect back
+to the client's specified address and port, while passive mode asks the server
+to setup an IP address and port for it to connect to. <address> should be one
+of:
+.RS
+.IP interface
+e.g. "eth0" to specify which interface's IP address you want to use (Unix only)
+.IP "IP address"
+e.g. "192.168.10.1" to specify the exact IP address
+.IP "host name"
+e.g. "my.host.domain" to specify the machine
+.IP "-"
+make curl pick the same IP address that is already used for the control
+connection
+.RE
+
+If this option is used several times, the last one will be used. Disable the
+use of PORT with --ftp-pasv. Disable the attempt to use the EPRT command
+instead of PORT by using --disable-eprt. EPRT is really PORT++.
+
+Since 7.19.5, you can append \&":[start]-[end]\&" to the right of the address,
+to tell curl what TCP port range to use. That means you specify a port range,
+from a lower to a higher number. A single number works as well, but do note
+that it increases the risk of failure since the port may not be available.
