Transport Preferences

The Transport tab in the Preferences window allows you to customize your network connection for RealPlayer. Most likely, if you are connecting to the Internet through a commercial Internet Service Provider (ISP), you will not have to change any of the items on this tab.

The description of these preferences assumes a basic knowledge of Internet protocols and firewalls. Changing these settings improperly can affect how your RealPlayer functions.

For more information about firewalls, refer to our Web site at:
