Question When I use the Windows firewall to block all outbound programs, I lose my WiFi connection?

Dec 11, 2019
Hi Folks - I need a little help please.

I have a test system running Windows 10 and I need to block ALL outgoing communication except being able to use the Internet through FireFox. When I block all outbound connections in the "Public" tab of the firewall properties, I lose connectivity to the WiFi network I'm connected to (WiFi status changes to "No Internet"). I would expect this.

Again, as expected, adding rules to allow Firefox, or Chrome, or IE does nothing since the method mentioned above is system-wide.

HOWEVER, re-enabled outbound connections in properties and then I alternately tried this another way, by creating an outbound firewall rule to just block all programs (as opposed to ports, etc.), and then I created another rule to allow Firefox. Unexpectedly, this had the same effect - WiFi is connected but shows "No Internet" which obviously prevents me from getting to the specific sites I need through FireFox. It is as if there is a "program" that is controlling WiFi connectivity and I need to allow something else (another program) to re-allow Internet connectivity. This is unexpected and I don't really know what the deal is. Extensive Googling hasn't turned up anything specific to this.

Can someone assist please???? THANK YOU!

A few things

1. If i called you on mute, would you be able to hear what i say? To give me a reply?

2. You need to allow ports 80,8080 inbound and outbound for access to https/http (web pages / the protocols)

3. Why do you want to do this? Anyways i got lazy once for a council i looked after this works if you want to block sites
