Windows 10: Windows 10 firewall? No internet access

Hiya, I'm wondering what settings I have to add to the windows firewall to have internet access. I have block incoming and outgoing connections except by a rule on, and port 80 with any program in outgoing and incoming. Just port 80 in outgoing & incoming does not allow internet access. What do I have to add to the firewall for this to work? When I turn off the firewall, I have internet access again.

Wi-Fi is on // No connection (after Windows Update)

still isn't working.

 

Wi-Fi is on // No connection (after Windows Update)

On Oct 13 windows updated.

The update must've invited malware into my computer. I tried to run my antivirus after the update but it said there's no connection. Google chrome lost connection as well and then I got a pop-up saying that Windows Defender found and blocked a "Severe Trojan
threat". So I deleted it and I still don't have connection... (weirdly) the only thing that works is the Explorer app. I have internet; the Wi-Fi works just fine but, everything else doesn't connect. It's something internal that must be causing
the problem and it all started after the update.

P.S.

It also changed my network from private to public so I had to fix that.

And YES, I did allow these programs through the Firewall so that's not the problem.

 

"Internet Access" is more than just port 80. For instance, HTTPS runs on port 443 as well. In addition to that, you need to open UDP port 53 to allow DNS through, otherwise there will be no name to IP translation. You will likely also need to open UDP ports 67 and 68 for DHCP to allow your computer to automatically assign it's IP address from a DHCP server.

Even then, depending on how you configured the firewall, you may need to open outgoing ports above 1024 because each connection requires two ports, the incoming and the outgoing port. Outgoing ports are randomly selected above 1024 (though most NAT traversal does this automatically, but if you override this in the firewall you can block that, and thus cannot get a full connection)

 

Hi, I have opened port 80, 443, 53, 67 & 68 on my computer incoming and outgoing. I still have no internet access. When I just had port 80 open, there was an exclamation mark on my WiFi. When I turned off the firewall & disconnected from the WiFi, then reconnected, it said that I had internet access. Now when I connect with the other ports open, it goes straight to internet access. However, there is no internet access for microsoft edge, or Firefox. Thanks for your help so far! =)
