24:
25: .SH NAME
26: CURLOPT_FTP_SKIP_PASV_IP \- ignore the IP address in the PASV response
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.
42: .SH DEFAULT
43: 0
