arduino - node.js not responding from intranet -

i have following node.js server defined , running

var httpserver = http.createserver(onrequest).listen(8080,'0.0.0.0',function(){     console.log("listening at: http://192.168.1.6:8080/");     console.log("server up"); });  seriallistener(debug); initsocketio(httpserver,debug); 

i can see page intranet. there no accessibility internet. have port forwarded 8080 , have tested using wamp server.

can me please. there funny thing - node.js server running , web page accessible when there internet connection available. why so?

if can see @ all, node working properly. if there's places can't see from, it's firewall issue, either on box or on switch in front of box.
