PHP Socket Programming : Server not accessible from outside network -

i working on php socket programming project. in project going create service in php socket. socket listen on 1 particular port. , client outside network able communicate on port.

till able create server , client in php socket programming. pc connected lan have use port forward connecting pc outside client. forward port 2000 , communication on port transfer pc ip address. have netgear router n150 wireless adsl .i add configuration on router. test port forwarding online @ site http://www.yougetsignal.com/tools/open-ports/ says port open.

i test code on locally (intranet), working fine. when trying run server on pc , client web server ipage hosting server. throws me error "server not connect server".

server.php

<?php  // set variables // lan ip $host = "192.168.0.5"; $port = 2000; // don't timeout! set_time_limit(0); // create socket $socket = socket_create(af_inet, sock_stream, 0) or die("could not create       socket\n"); // bind socket port $result = socket_bind($socket, $host, $port) or die("could not bind socket\n"); // start listening connections $result = socket_listen($socket, 3) or die("could not set socket  listener\n");   $spawn = socket_accept($socket) or die("could not accept incoming  connection\n"); // read client input $input = socket_read($spawn, 1024) or die("could not read input\n"); // clean input string $input = trim($input); echo "client message : " . $input; // reverse client input , send $output = strrev($input) . "\n"; socket_write($spawn, $output, strlen($output)) or die("could not write      output\n"); // close sockets socket_close($spawn); socket_close($socket); ?> 

client.php

        <?php          //my public ip         $host = "117.223.90.191";         // port on port forword         $port = 2000;         $message = "hello server";         echo "message server :" . $message;         // create socket         $socket = socket_create(af_inet, sock_stream, 0) or die("could not create socket\n");         // connect server         $result = socket_connect($socket, $host, $port) or die("could not connect server\n");         // send string server         socket_write($socket, $message, strlen($message)) or die("could not send data server\n");         // server response         $result = socket_read($socket, 1024) or die("could not read server response\n");         echo "reply server  :" . $result;         // close socket         socket_close($socket);         ?> 

any suggestion problem. think many have same problem me.

even if think problem in lan forwarding, try testing :

telnet 117.223.90.191 2000 

another thing try make server listen on interfaces

$host = "0.0.0.0";
