Kaspersky firewall - how to block all incoming, but allow for established internet traffic

[Guest]

I have created such rule and keep it on the top:

However I see many public IPs trying to reach from 443 port in logs. I’m not sure if it works properly. I think It might cause some connection issues. Also I have some connection issues with github. Sometimes I get “ERR_CONNECTION_TIMED_OUT”, then i execute ipconfig /flushdns, and it works for a moment after that, but then stops working again.

It blocks also some traffic from 1.1.1.1 (my DNS) from port 853. This might cause issues described above.

Edit: Github doesn’t work on other devices too. It’s probably ISP problem.
