How do I make FactoryPMI work with the Windows Firewall?

This post covers it

FactoryPMI only needs to be able to communicate over a single, user definable TCP port. To work with any firewall, simply create an exception for the computer to listen over that port. If you want to get more secure, you can only allow the FactoryPMI service program to be able to listen to that port. Typical settings:

Path: C:\Program Files\Inductive Automation\FactoryPMI\FPMIService.exe
Port: 8080
