You can enable access to a common application from a specific
PC on your network.
If you want to allow access to an application that is not included
on the above list of common applications, you can create and
enable a custom application.
Configuring custom applications
If you want to enable access to an application that does not
appear on your device’s default list of common applications you
can create a custom application.
In order to create a custom application, you must know:
1. the protocol used by the application (e.g., TCP, UDP and so
on)
2. the primary port or range of ports used by the application
3. whether the application requires a trigger, and if so, the
secondary port or range of ports used by the application
4. the address translation type used by the trigger
Your application provider or games manufacturer should
provide you with these details.
