Ports for streaming from the Content Server
Streaming Windows Media from the Content Server uses the following ports:
Port
Streaming Media Protocol
Firewall Information
554
RTSP
At least one of these ports needs to be open
between the Content Server and the Windows
Media player. For true (RTSP) streaming, open
port 554. See the note below.
8080
HTTP
Note: The Windows Media player will automatically use protocol rollover if necessary. The default
streaming protocol for the Windows Media player is RTSP on port 554. If the player cannot obtain the
stream using RTSP (because the port is blocked on a firewall, for example), then it will automatically
rollover to MMS. MMS (port 1755) is a deprecated streaming protocol and is not used as a streaming
transport for Windows Media Player version 9 and above. The player will then try HTTP on port 80.
The Content Server will redirect any requests for Windows Media streams on port 80 to the correct
HTTP port used by the Windows Media Streaming Server on the Content Server (port 8080).
Streaming Windows Media from the Content Server to the Silverlight player uses the following port:
Port
Streaming Media Protocol
Firewall Information
8080
HTTP
Needs to be open between the Content Server
and the Silverlight player.
Note: The Silverlight player will request the stream on port 80 because this is the default HTTP port.
The Content Server will redirect any requests for Windows Media streams on port 80 to the correct
HTTP port used by the Windows Media Streaming Server on the Content Server (port 8080).
Serving MPEG-4 for QuickTime, MPEG-4 for Flash or Real Media from Content Server using the
default "Local IIS Web Server" Media server configuration uses the following port:
