Firewalls and the RealSystem
Firewalls create barriers in order to prevent unauthorized access to a network. Think of the Internet as a series of hallways. Firewalls are the security doors through which some people (i.e. data) may pass and others may not.
RealSystem content usually passes through these barriers without trouble, but sometimes it is necessary to change your configuration settings. With the proper configuration settings, you can enjoy RealAudio and RealVideo.
