    Yes... typically you would want that on.

    This firewall doesn’t do anything by default when enabled. It just lets you block apps from setting up inbound connections. Not every app you install is even capable of this and those that are usually have this functionality for a reason, in which case blocking such connections would limit their usefulness.

    The firewall is only really useful if you specifically want to block certain apps from setting up such connections or want to be alerted if any app does this and want to approve them first. If not, there isn’t much of a reason to enable it and you can spare yourself the trouble.
