Configuring RealPlayer version G2 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. If you are not sure which method to choose, click Auto Configure. 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, run Auto-Configure:

  1. In RealPlayer, click Preferences from the Options menu.
  2. Click the Transport tab.
  3. Click the Automatically Select Best Transport option.
  4. Click the Auto-Configure button. The Automatic Transport Configuration window appears.
  5. Run the Auto-Configure by clicking the OK button.

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.

To configure RealPlayer G2 to receive UDP through a single port:

  1. In RealPlayer, click Preferences from the View menu (Windows) or the Edit menu (Macintosh).
  2. Click the Transport tab.
  3. Click Use Specific UDP Port and type the number of the UDP port where you want to receive the UDP streams. 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 G2 to use only TCP to stream audio:

  1. In RealPlayer, click Preferences from the Options menu.
  2. Click the Transport tab.
  3. Click Use specified transports.
  4. Click Change Settings to access the Specify Transports window where you can specify the modes with which you can receive data. When you are finished with the Specify Transports window, click the OK button.

  5. Click OK.
  6. Click OK on the Preferences windows to save your changes.

Receiving Content 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 G2 to receive content through HTTP Only:

  1. In RealPlayer, click Preferences from the Options menu.
  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 the Use HTTP Only option.
  6. Click the OK button on the Preferences window to save your changes.
