的Winsock只接受来自同一台计算机的连接，但不能从同一网络

Question

所以我一直在这个指南

要建立在C一个简单的TCP服务器下面，这是我想出了代码：
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basicly复制和改变的东西）
现在的问题是，我只能连接到这台服务器使用相同的连接，我不能使用网络中的不同计算机连接到它，即使我打开端口（实际上应该不重要），它不会接受来自我网络上不同计算机的连接（仅来自同一台计算机）

Answer 1

我只需要在防火墙上打开端口
