7.3.1 How the Special Application Feature Works

The Special App feature works by monitoring any user defined outgoing trigger

ports. When the XRouter Aero receives a request on these outgoing trigger ports

it will open a range of user defined incoming ports to the computer that originally

sent the request to. Each computer on the network can use the Special App.

Since the Special App feature works upon an outgoing trigger port, the user

defined incoming ports are closed before the computer accesses the outgoing

trigger port. In other words, incoming ports are closed until a proper Internet

request is made. Also, the incoming ports will automatically close if the XRouter

Aero does not sense any activity for an extended period.

7.3.2 How to Use the Special Application Feature

To use this feature, you must know what the outgoing trigger ports are for the

given application that needs two-way communications. You must also know the

incoming ports that are required for the data that needs to come back into the

network. For example, QuickTime typically uses port 554 as the initial outgoing

communication port. However, the actual data is then sent back through different

incoming ports. In the case of QuickTime, ports 6970-6999 need to be open to the

computer so that incoming data can reach the computer requesting the

QuickTime stream. To enable Special App feature, click the check box next to the

one of the Special entries. The Special App entries consist of the following fields

and must be filled in:

1 2 ... 27 28 29 30 31 32 33 34 35 36 37 ... 55 56
