c++ - Can't connect to remote ip -

i'm trying connect client server. local address (127.0.0.1) works fine, when try use remote address, doesn't work. search thing on internet couldn't find anything.

server side:

bool start_server() {     int = 1;     if(wsastartup(makeword(2,0),&wsadat) != 0)     {          cout << "wsa error!" << endl;          system("pause");          return false;     }     if ( lobyte( wsadat.wversion ) != 2 || hibyte( wsadat.wversion ) != 0 )     {       cout << "bad version of winsocket" << endl;       system("pause");       wsacleanup();       return 0;     }        serwer = socket(af_inet, sock_stream, 0);     if(serwer == invalid_socket)     {         cout << "can't create socketa!" << endl;         system("pause");         wsacleanup();         return 0;     }     int port;     cout << "port input " << endl;     cin >> port;                                             // 13056     sockaddr_in sockaddr;     sockaddr.sin_port =  htons(port);     sockaddr.sin_family = af_inet;     sockaddr.sin_addr.s_addr = inaddr_any;     setsockopt( serwer, sol_socket, so_reuseaddr, ( char * ) &i, sizeof ( ) );     if(bind(serwer,(sockaddr *)(&sockaddr), sizeof(sockaddr)) == socket_error)     {         cout << "couldn't bind socket" << endl;         system("pause");         wsacleanup();         return 0;     }     for(int = 0; < max_clients; i++)     client[i].connected = false;     if(listen(serwer,somaxconn)==socket_error)     {         cout << "listening error!" << endl;         system("pause");         wsacleanup();         return 0;     }     cout << "serwer created!" << endl;     unsigned long b = 0;     ioctlsocket ( serwer, fionbio, &b );     return 1; } 

after have accept function on program blocking:

accept(serwer,(sockaddr *)(&current_client->address),&current_client->address_length); 

client side:

bool start_client() {     wsadata wsadat;      if(wsastartup(makeword(2,0),&wsadat) != 0)         cout << "wsa error!\n";     if ( lobyte( wsadat.wversion ) != 2 || hibyte( wsadat.wversion ) != 0 )     {         cout << "wrong version of winsocket\n";         wsacleanup();                     return false;     }      socket klient;      klient = socket(af_inet, sock_stream, 0);     if(klient == invalid_socket)             {         cout << "can't create socket socketa!\n";         wsacleanup();                     return false;     }     sockaddr_in sockaddr;     sockaddr.sin_port = htons(port);                        // 13056     sockaddr.sin_family = af_inet;     sockaddr.sin_addr.s_un.s_addr = inet_addr("*********");      // remote address     while(connect(klient, (sockaddr *)(&sockaddr), sizeof(sockaddr)) != 0)      {         cout << "trying connect " << wsagetlasterror() << "\n";         sleep(500);     }     cout << "connected!\n"; } 

i have added both client , server applications firewall rules , have tried connect them on couple ports. server side listening sure (here on different port):

there nothing wrong code.

not routers , network address translators (nats) support hairpinning, ability connect public ip within private network behind nat.

if nat/router support this, need configure port-forwarding rule on nat/route map incoming tcp traffic on port 14354 (your server listening port) internal ip address of 192.168.0.10. think of router perspective, if sees , incoming connection request on public ip - needs know host on private network forward connection to.
