If your Windows Media server is protected by a firewall, you can still receive source content from a Windows Media Encoder located outside of the firewall using a feature called HTTP streaming.
This option is designed to enable a Windows Media Encoder on the Internet to distribute an ASF stream to a Windows Media server located within a firewall. Standard firewall configurations do not allow distribution of a stream from Windows Media Encoder inside a firewall out to a Windows Media server installation on the Internet.
HTTP streaming is enabled by default for QuickStart configurations. The port reference for HTTP connections is listed in the stream reference box of the encoder. To change the port or to disable HTTP streaming, clear the checkbox for HTTP streaming on the output properties page of your encoder configuration.
If you use the Template or Custom configuration methods, you can select HTTP streaming from the Output Settings, Transmissions page of the configuration wizard.
