Configuring RealPlayer versions 4.0 and 5.0 to work from behind a firewall

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

The Auto-Configure method automatically detects which transport methods are available to your RealPlayer and selects the highest quality method.Otherwise, ask your firewall administrator which option you should choose. You will need to know the port numbers for the UDP and TCP choices.

Auto Configuration

If your configuration changes, or if you lose the ability to play content, use the auto configuration button to have RealPlayer select the best method available.

  1. In RealPlayer, click Preferences from the View menu (Windows) or the Edit menu (Macintosh).
  2. In the Preferences window, click the Transport tab.
  3. Click Automatically Select Most Efficient Transport.
  4. Click Auto-Configure. The Automatic Transport Configuration window appears.
  5. Run the Auto-Configure by clicking OK.

Receiving Clips Through a Single UDP Port

RealPlayer 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. RealPlayer also offers the ability to limit those inside a firewall to receive UDP on only one port, which makes router configuration easier for the firewall administrator.

To configure RealPlayer versions 4.0 and 5.0 to receive UDP through a single port:

  1. In RealPlayer, click Preferences from the View menu (Windows) 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

RealPlayer 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 RealPlayer versions 4.0 and 5.0 to use only TCP to stream media:

  1. In RealPlayer, 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 Change Settings. 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.

Receive Clips Through HTTP Only

RealPlayer 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 HTTP Only option allows almost all Players behind a firewall to access RealAudio and RealVideo content. Quality may not be as good as the other options, however.

To configure RealPlayer versions 4.0 and 5.0 to receive content through HTTP Only:

  1. In RealPlayer, click Preferences from the View menu (Windows) or the Edit menu (Macintosh).
  2. In the Preferences window, click the Transport tab.
  3. Click Use Specified Transport.
  4. Click Specify Transports. The Specify Transports window appears:

  5. Click Use HTTP Only.
  6. Click OK in the Specify Transports window.
  7. Click OK in the Preferences window to save your changes.
