Multiplayer game in webplayer not working on server

Hello.

I have a demo networking project from below links.

http://answers.unity3d.com/questions/47544/multiplayer-tutorials.html

When I run the game in local network.It's working fine.

But when I upload it to my website,It doesn't seems to be work.

When I open my webpage that contains Unity game,

Start server is probably starting server in local.

So if I open that webpage in multiple browsers of same Machine , IT works fine.

But cannot connect that game in other machine..

What should I do.

Plz suggest me ..thnx in advance..
