Configuring RealPlayer 8 to work from behind a firewall

If your computer is on a network protected by a firewall, and you are having trouble playing media with RealPlayer, 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 Internet Service Provider (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. Start RealPlayer 8.
  2. Click the View menu and choose Preferences.
  3. Click the Transport tab.
  4. Click Automatically Select Best Transport.
  5. Click the Auto-Configure button. The Automatic Transport Configuration window appears.
  6. Click OK to start the Auto-Configure process.

Receiving Clips Through a Single UDP Port

RealPlayer 8 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 8 to receive UDP through a single port:

  1. Start RealPlayer.
  2. Click the View menu and choose Preferences.
  3. Click the Transport tab.
  4. Select Use Specific UDP Port and type the UDP port value. Ask your network manager or firewall administrator which port number to use.

Receiving Clips Through TCP Only

RealPlayer 8 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.

Receiving Content Through HTTP Only

RealPlayer 8 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 computers behind a firewall to access RealAudio and RealVideo content with RealPlayer 8. Quality may not be as good as the other options, however.

To configure RealPlayer 8 to receive content through HTTP Only:

  1. Start RealPlayer 8.
  2. Click the View menu and choose Preferences.
  3. Click the Transport tab.
  4. Click Use Specified Transport.
  5. Click the RTSP Settings button.
  6. Click Use HTTP Only.
