Configuring the RealPlayer to Work Through a Firewall

The HTTP-Only option allows almost all Players behind a firewall to access RealAudio and RealVideo content. You must have RealPlayer version 5.0 or higher to receive HorizonLive content in this manner.

To determine if you have one of these versions of the RealPlayer:
Open the RealPlayer, click on the "Help" menu, and click on the "About" tab ("About RealPlayer" for G2). A message box will be displayed listing the version of the RealPlayer that is installed on your system. (Version numbers beginning with 5 are RP 5.0 and versions beginning with 6 are G2 RealPlayers.)

To configure the RealPlayer 5.0 to receive content through HTTP-Only:

1. In your RealPlayer 5.0, click "Preferences" from the View menu.
2. In the Preferences window, click the Transports option.
3. Click the "Use Specified Transports" option.
4. Click the "Specify Transports" button. The "Specify Transports" window appears.
5. Click the "Use HTTP Only" option. Click OK in the "Specify Transports" window.
6. Click the OK button on the "Preferences" window to save your changes.

To configure the RealPlayer 7 (G2) to receive content through HTTP-Only:

1. In your RealPlayer G2, click "Preferences" from the Options menu.
2. In the "Preferences" window, click the Transports option.
3. Click the "Use Specified Transports" option.
4. Click the "PNA Settings" button. The "PNA Transport Settings" window appears.
5. Click the "Use HTTP Only" option. Click OK in the "Specify Transports" window.
6. Click the OK button on the "Preferences" window to save your changes.

Working with Proxy Servers to allow user to receive audio using RealPlayer

If a user is not getting any audio - even though they are using an acceptable web browser and have installed the proper RealPlayer plugin - it is possible that a proxy server is in use at the IT or organization network level. If this is the case, one will need to identify the name and port of the proxy server being used and supply this information in the RealPlayer preferences.

NOTE: This procedure often needs to be followed in conjunction with configuring the RealPlayer to receive audio through HTTP only, as described in the section of this guide called "Configuring the RealPlayer to Work Through a Firewall."
