What ports do I need to open on my firewall to allow
streaming audio
Thanks

Typically 80 if you're not running a web server, any other port you desire
if you are. Just turn on HTTP in Windows Media Services and specify the
port, it defaults to run on 80 if IIS is not running on the box.
The key is to tell your users the port you've chosen for their URLs
(http://mydomain.com:8080/myfile.wma is how you link to a file over port
8080, etc)
Some folks, and most books regurgitating MSDN articles for older versions of
Windows Media will tell you otherwise but in a nutshell: The port is up to
you, no other protocol beyond HTTP is required (MS advises against using
others, strongly advising against the UDPs in most cases)
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwmt/html/opti
mize_web.asp
Plus, it appears that using MMS:// in the url is not only not needed, but
that in most cases using it has the negative effect of delaying the user
experience for absolutely no good reason. It tells the player to rollover
through all of the protocols that aren't used before it ends up at the
advised HTTP.
Hope that helps.

Configuring firewalls for unicast streaming
To configure a firewall for unicast streaming, you must open the ports on
the firewall that are required for the connection protocols enabled on your
server. If you are streaming content by using either the MMS or RTSP
protocols, you need to support both the User Datagram Protocol (UDP) and
Transmission Control Protocol (TCP).
To enable Windows Media Player and other clients to use the HTTP, RTSP, or
MMS protocols to connect to a Windows Media server that is behind a
firewall, open the following ports.
Ports Description
In: TCP on port 80, 554, 1755 The Windows Media server uses the TCP In
ports to accept an incoming HTTP connection (port 80), RTSP connection (port
554), or MMS connection (port 1755) from Windows Media Player and other
clients.
In: UDP on port 1755, 5005 The Windows Media server uses UDP In port
1755 to receive resend requests from clients streaming by using MMSU and UDP
In port 5005 to receive resend requests from clients streaming by using
RTSPU.
Out: UDP between ports 1024-5000. The Windows Media server uses UDP
Out ports 1024-5000 to send data to Windows Media Player and other clients.
Thank you for using Windows Media Services
