[Alfred Koebler <ak@xxxxxxxxxxxx>]

Hallo everybody,
 

there is a addition to the FW1 monitor dissector patch.

It allows to show the information in a additional column.

Try to switch on:
- Edit - Preferences - Column - Add New
  Column title:  IF/DIR
  Column format: FW-1 monitor if/direction
  - Save - Apply - OK



Greetings from Germany
