| 3 | Help: Use PORT instead of PASV |

| 8 | Reverses the default initiator/listener roles when connecting with FTP. This |
| 9 | option makes curl use active mode. curl then tells the server to connect back |
| 10 | to the client's specified address and port, while passive mode asks the server |
| 11 | to setup an IP address and port for it to connect to. <address> should be one |
| 12 | of: |
| 13 | .RS |
| 14 | .IP interface |
| 15 | i.e "eth0" to specify which interface's IP address you want to use (Unix only) |
| 16 | .IP "IP address" |
| 17 | i.e "192.168.10.1" to specify the exact IP address |
| 18 | .IP "host name" |
| 19 | i.e "my.host.domain" to specify the machine |
| 20 | .IP "-" |
| 21 | make curl pick the same IP address that is already used for the control |
| 22 | connection |

| 25 | If this option is used several times, the last one will be used. Disable the |
| 26 | use of PORT with --ftp-pasv. Disable the attempt to use the EPRT command |
| 27 | instead of PORT by using --disable-eprt. EPRT is really PORT++. |
| 28 | |
| 29 | Since 7.19.5, you can append \&":[start]-[end]\&" to the right of the address, |
| 30 | to tell curl what TCP port range to use. That means you specify a port range, |
| 31 | from a lower to a higher number. A single number works as well, but do note |
| 32 | that it increases the risk of failure since the port may not be available. |
