+# `--ftp-port`
+
+Reverse the default initiator/listener roles when connecting with FTP. This
+option makes curl use active mode. curl then commands 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:
+
+## interface
+e.g. **eth0** to specify which interface's IP address you want to use (Unix only)
+
+## IP address
+e.g. **192.168.10.1** to specify the exact IP address
+
+## hostname
+e.g. **my.host.domain** to specify the machine
+
+## -
+make curl pick the same IP address that is already used for the control
+connection. This is the recommended choice.
+
+##
+
+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++.
+
+You can also 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.
