Does it work like expected from within your network? I didn’t realise this was an “external connectivity” problem until just now.
How come you wanna open your server for public streaming (and downloading of your mp3s)?
And, I can assure you, that if you can access your server from the internet, it has an ip-address.
Your problem is that when FirePlay asks for info, for example your Music Servers name, there needs to be a “crossdomain.xml”-file at the xml-serving end. Now, unfortunately, everything that resides in the “admin-root” directory has first to be authenticated before it can be accessed. Since there is no such mechanism in Flash, the xml-requests goes unanswered, unless you first authenticate yourself to your admin-root.
Try this:
1. Using your current setup, to go to “www.yourserver.com:3689/admin-root”
2. There should be a dialog. Authenticate yourself.
3. Now, in the same browser window, go to “fireplay.yourserver.com” and see if it works.
If the above works, I’m afraid I have no solution for you.
