                     27: .SH SYNOPSIS
                     28: #include <curl/curl.h>
                     29: 
                     30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_SKIP_PASV_IP, long skip);
                     31: .SH DESCRIPTION
                     32: Pass a long. If \fIskip\fP is set to 1, it instructs libcurl to not use the IP
                     33: address the server suggests in its 227-response to libcurl's PASV command when
                     34: libcurl connects the data connection. Instead libcurl will re-use the same IP
                     35: address it already uses for the control connection. But it will use the port
                     36: number from the 227-response.
                     37: 
                     38: This option thus allows libcurl to work around broken server installations
                     39: that due to NATs, firewalls or incompetence report the wrong IP address back.
                     40: 
                     41: This option has no effect if PORT, EPRT or EPSV is used instead of PASV.
