| Pull RealPlayer streaming audio through a firewall |
| Are you aware that some Web sites prefer to serve streaming audio via Microsot's RealPlayer |
| rather than in the Media Player format (or even accepting both formats)? Because of this, you |
| might need to change your firewall configuration to allow audio streams with RealPlayer. Or, as |
| with Media Player, you can configure RealPlayer to use HTTP port 80, which is probably already |
| The default port for UDP streams in RealPlayer is 7070. So you can open port 7070 on the firewall |
| and get RealPlayer to work through the firewall. Another option is to specify a different port in |
| RealPlayer and open that port on the firewall. In RealPlayer, choose View | Preferences, and then |
| click the Transport tab. Select the option Use Specific UDP Port(s) and enter the single port or port |
| range that you opened on the firewall. |
| If you don't have control of the firewall or can't get the network administrator to make any |
| changes, you can configure RealPlayer to use HTTP port 80 only. To do so, choose View | |
| Preferences, and click the Transport tab. Click Use Specified Transport and click RTSP Settings. |
| Then, select the option Use HTTP Only and click OK. |
