Configuring RealAudio Player version 3.0 to work from behind a firewall

If your RealAudio Player is behind a firewall, and you are having trouble playing media on some sites, the firewall may not be configured to allow RealAudio Player traffic.

First, you might want to find out whether a firewall is the problem. If you determine that there is a firewall on your organization's network or your ISP, the ideal solution is for the firewall administrator to allow RealPlayer traffic on the firewall.

If you know that there is a firewall in place that has not yet been configured to allow RealPlayer traffic, RealPlayer can receive streamed media without compromising the security of the firewall. Before implementing the steps in this section, be sure to check with your firewall administrator regarding your organization's policies on Internet access.

If you are not sure which method to choose, select Automatically select most efficient transport on the Transport tab of the Preferences dialog box. This option automatically detects which transport methods are available to your RealAudio Player and selects the highest quality method. Otherwise, ask your firewall administrator which option you should choose and which port numbers you should use.

• Configure RealAudio Player 3.0 to receive UDP through a single port
• Configure RealAudio Player 3.0 to receive TCP-only

Receiving Clips Through a Single UDP Port

RealAudio Player automatically selects the most efficient transport for your network without any intervention. You should only change this setting if you are experiencing problems receiving RealAudio and RealVideo clips or you have been notified by your network administrator that you should change this setting.

The UDP option offers better sound quality than TCP.

To configure RealAudio Player version 3.0 to receive RealAudio clips through a single UDP port:

1. In RealAudio Player, click Preferences from the View menu (Windows and UNIX) or the Edit menu (Macintosh).
2. In the Preferences window, click the Transport tab.
3. Click Use specific UDP port and type the number of UDP port which is configured to pass through your organization's firewall. Ask your network manager or firewall administrator which port number to use.

   

4. Click OK to save your changes.

Receiving Clips Through TCP Only

RealAudio Player automatically selects the most efficient transport for your network without any intervention. You should only change this setting if you are experiencing problems receiving RealAudio and RealVideo clips or you have been notified by your network administrator that you should change this setting.

To configure RealAudio Player version 3.0 to use only TCP to stream audio:

1. In RealAudio Player, click Preferences from the View menu (Windows) or the Edit menu (Macintosh).
2. In the Preferences window, click the Transport tab.
3. In the Network Transport box, click Use specified transports.
4. Click Attempt to use TCP for all content.

   

   When you are finished with the Specify Transports window, click OK.

5. Click the OK button on the Preferences window to save your changes.
