To do this, you will need to create incoming and outgoing traffic rules to enable Orb streaming from that PC to either an Internet-connected device or a device within your Local Area Network (LAN), such as another PC, a laptop, a PDA, or a game console (Nintendo Wii, Sony PS3, Xbox 360, etc.).
Every UI and navigation will be different so, if your firewall software is not among the five listed below, refer to your firewall help guide for specific step-by-step instructions on how to create incoming and outgoing traffic rules for the three Orb applications: Orb.exe, OrbTray.exe and OrbStreamerClient.exe.
The ports you need to open on your Orb PC are:

For
Windows media (WMP, WinAmp, TCPMP, or Flash Player):
TCP port 80 (or port
81, if you have another program like Skype running on your Orb PC.

For
Real media (RealPlayer):
TCP port 554 and
UDP port 13398

For
3GP media (Quicktime or other 3GP player):
TCP port 554 and
UDP ports 13398 to 13401
