No remote connection to Ratchet/Websocket possible
Hi there,

currently I'm working on an application which is supposed to push tickets to a JavaScript-Client/Browser.  If browser and WebSocket-Service reside on the same machine, all works well!

But if I deploy the Service onto a remote Server (running on Fedora with Apache/httpd), my Browser can't connect to the Websocket. I configured the firewall to open up port 8080 and no other process is listening on this port!

The relevant code section looks like this:

`$ratchetApp = new Ratchet\App('koda-cs-vm-dw', 8080, '192.168.230.116', $loop);
$ratchetApp->route('/koda-webSocketServer', $KoDAWSS_Ratchet, ["*"]);`

"koda-cs-vm-dw" is the host, where the Websocket-Service resides.
192.168.230.116 is the current IP-address of the server.
"/koda-webSocketServer" is the endpoint, where the browser should connect to.

I also tried setting the third parameter of App() to "0.0.0.0" but without any success. 

Any advice is greatly appreciated!

Regards,
Dominik

EDIT: When I try to access the Websocket with Chrome, the debug-console shows:

`WebSocket connection to 'ws://koda-cs-vm-dw.xbreuer.local:8080/' failed: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT`
