CURLOPT_LOCALPORT - set local port number to use for socket #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOCALPORT, long port); Pass a long. This sets the local port number of the socket used for the connection. This can be used in combination with CURLOPT_INTERFACE(3) and you are recommended to use CURLOPT_LOCALPORTRANGE(3) as well when this option is set. Valid port numbers are 1 - 65535. 0, disabled - use whatever the system thinks is fine All

if(curl) {
 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/foo.bin");
 curl_easy_setopt(curl, CURLOPT_LOCALPORT, 8080L);
 /* and try 20 more ports following that */
