I did, here is my relevant code segment, but the destination still shows that I sent from another ip than what I set here:

tcp::resolver resolver(fIo_service);
                tcp::resolver::query query(tcp::v4(), host, port);
                tcp::resolver::iterator iterator = resolver.resolve(query);
                fpSocket = new tcp::socket(fIo_service);
                if (fpSocket == nullptr)
                        return ;
                fpSocket->open(boost::asio::ip::tcp::v4());
                fpSocket->bind(boost::asio::ip::tcp::endpoint(boost::asio::ip::address::from_string("<ip>"), 0));
                boost::system::error_code errcode;
                boost::asio::connect(*fpSocket, iterator, errcode);

Call bind() before connect().

One approach is to execute the tasks in a separate process. The process
can easily be killed, and it takes care of the memory leaks.
