FileMaker Client port range

[Clinton]

Does anyone know the range of ports that is required for FileMaker Pro (or any FM client) to access an application remotely?

The FilerMaker Server guide mentions only the ports necessary for the server (5003, 50003, 50006, 591, etc), but there is no mention of what ports the client uses to connect. Due to some recent complications, a client of mine is having to shut down ports, and needs to know what range the FM client will need open. So far, it seems to be a random port, between 3000 and 4000, but I would like to know something more specific.

Officially, the only documented port for FileMaker I could find was 2399 (Data Access Layer).

Any help would be greatly appreciated.
