Portmappings on UPnP-NAT(s) using C++, winsock2, xerces2.8 (Linux friendly code)

Download source - 30.5 KB

Introduction

This article introducing a portmapping method and some IGD's UPnP SOAP actions using C++ without the Microsoft's COM library for the UPnP. So sorry, you have to setup libraries and VC paths like an image[red square] below. This project using boost-cpplib and xerces (DOM parsing). But I couldn't upload libraries with my source code because of an upload timeout with large file size.

I had just tested soap responses from UPnP-enabled routers. I had not tested the connections and data streams as points of this article.

Sorry for potential bugs and my poor English.

Multiple NICs and multiple routers are supported. But CASCADED NATs are not supported.

Background

I want to implement the portmapping without third party (UPnP) libraries and attempt to write platform independent code AS POSSIBLE.

Using the Code

#include "stdafx.h"

#include "Manager/ApplicationManager.h"
#include "Manager/COMManager.h"

#include "Network/NetworkManager.h"
#include "Network/NetworkHelper.h"

#include "NATBreak/UPNPNATServiceTypes.h"
#include "NATBreak/IGDDiscoverProcess.h"
#include "NATBreak/UPNPNATHTTPClient.h"

using namespace std;
using namespace boost;

thread_group tg;

int _tmain(int argc, _TCHAR* argv[])
{
	ApplicationManager am;
	NetworkManager nm;

	try
	{	
		IGDDiscoverProcess discoverer( 500000 );

		tg.create_thread( ref( discoverer ) );
		tg.join_all();

		IGDDiscoverProcess::IGDControlInformations cinfos = 
			discoverer.GetAllIGDControlInformations();
		boost_foreach( IGDDiscoverProcess::ControlInfo info, cinfos )
		{
			if( info.has_problem )
			{
				cout << "has problem" << endl;
				continue;
			}

			if( info.service_type == UPNPSERVICE_LAYER3FORWARDING1 )
			{
				// Layer3Forwarding:1 srvice

				UPNPNATHTTPClient soap( info.ip, info.port );

				soap.GetDefaultConnectionService
				( info.control_url, info.service_type );
			}
			else if( info.service_type == UPNPSERVICE_WANIPCONNECTION1 )
			{
				// WANIPConnection service
				UPNPNATHTTPClient soap( info.ip, info.port );
				string ip;
				UPNPNATHTTPClient::SoapResult res = 
					soap.GetWANIPAddress( 
					ip, info.control_url, info.service_type 
					);
				cout << "WAN IP : " << ip << endl;

				UPNPNATHTTPClient::SoapResult soap_res;
				soap_res = soap.AddPortMapping( 
				    string("test"), 12345, 12345, string("UDP"), 
				    string("192.168.0.2"), // own nic's address 

                                         info.control_url, info.service_type 
					);
				if( UPNPNATHTTPClient::SoapSucceeded == soap_res )
				{
					cout << "portmapping succeeded." << endl;
				}

				soap_res = soap.DeletePortMapping(
					12345, string("UDP"), info.control_url, 
					info.service_type
					);
				if( UPNPNATHTTPClient::SoapSucceeded == soap_res )
				{
					cout << "delete portmapping succeeded." 
						<< endl;
				}
			}
			else if( info.service_type == 
				UPNPSERVICE_WANCOMMONINTERFACECONFIG1 )
			{
				// WANCommonInterafaceConfig:1 srvice

				UPNPNATHTTPClient soap( info.ip, info.port );

				string ip;
				soap.GetActiveConnection( 0,  
					info.service_type, info.control_url );
			}
		}
	} 
	catch( IGDDiscoverProcess::exception &e )
	{
		cout << e.what() << endl;
	}

	_CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);
	return 0;
