NAME

     CURLOPT_FTP_SKIP_PASV_IP - ignore the IP address in the PASV
     response

SYNOPSIS

     #include <curl/curl.h>

     CURLcode           curl_easy_setopt(CURL            *handle,
     CURLOPT_FTP_SKIP_PASV_IP, long skip);

DESCRIPTION

     Pass a long. If skip is set to 1, it  instructs  libcurl  to
     not  use  the  IP  address  the  server suggests in its 227-
     response to libcurl's PASV command when libcurl connects the
     data  connection.  Instead  libcurl  will re-use the same IP
     address it already uses for the control connection.  But  it
     will use the port number from the 227-response.

     This option thus allows libcurl to work around broken server
     installations  that  due  to NATs, firewalls or incompetence
     report the wrong IP address back.

     This option has no effect if PORT,  EPRT  or  EPSV  is  used
     instead of PASV.

DEFAULT

     0

       curl_easy_setopt(curl, CURLOPT_FTP_SKIP_PASV_IP, 1L);
       ret = curl_easy_perform(curl);

       curl_easy_cleanup(curl);
     }
