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.

Please scroll through the choices below to select the option which best describes you and the firewall information relevant to your needs.
