c - Winsock 只接受来自同一台计算机的连接，但不接受来自同一网络的连接

Question

所以我一直在遵循本指南
http://www.binarytides.com/winsock-socket-programming-tutorial/
要在c中创建一个简单的tcp服务器，这是我想出的代码:
https://pastebin.com/CDxiLv3b

int c;
char client_message[2000];
int recv_size;
printf("\nInitialising Winsock...");
if (WSAStartup(MAKEWORD(2, 2), &wsa) != 0)
{
    printf("Failed. Error Code : %d", WSAGetLastError());
    return 1;
}

printf("Initialised.\n");

//Create a socket
if ((server_socket = socket(AF_INET, SOCK_STREAM, 0)) == INVALID_SOCKET)
{
    printf("Could not create socket : %d", WSAGetLastError());
}

printf("Server Socket created.\n");

memset(&server_addr, 0, sizeof(server_addr));
//Prepare the sockaddr_in structure
server_addr.sin_family = AF_INET;
server_addr.sin_addr.s_addr = INADDR_ANY;
server_addr.sin_port = htons(port);

//Bind
if (bind(server_socket, (struct sockaddr *)&server_addr, sizeof(server_addr)) == SOCKET_ERROR)
{
    printf("Bind failed with error code : %d", WSAGetLastError());
}

printf("Bind to port %d done.\n", port);

//Listen to incoming connections
listen(server_socket, 3);

//Accept and incoming connection
puts("Waiting for incoming reverse shell...");

c = sizeof(struct sockaddr_in);
while ((client_socket = accept(server_socket, (struct sockaddr *)&client_addr, &c)) != INVALID_SOCKET)
{
    puts("Connection accepted");
    if ((recv_size = recv(client_socket, client_message, 2000, 0)) == SOCKET_ERROR)
    {
        puts("recv failed");
        break;
    }
    client_message[recv_size] = '\0';
    strcpy_s(path, MAX_PATH_LEN, client_message);
    break;
}

if (client_socket == INVALID_SOCKET)
{
    printf("accept failed with error code : %d", WSAGetLastError());
    return 1;
}

return 0;

(是的，我基本上复制和改变了东西)
现在的问题是，我只能使用相同的连接连接到该服务器，我无法使用网络中的不同计算机连接到它，即使我打开端口(实际上并不重要)，它也不会接受来自不同计算机的连接在我的网络上(仅来自同一台计算机)

Answer 1

我只需要打开防火墙上的端口
