Firewall. Drop everything except used Ports.

How can I configure the Firewall App that it drops everything but the necessary Pakets for basis functionality (Web Frontend, Device Portal, etc.)?

I tried to set the Default Policy of the DefaultChains (Input AND/OR Output) to drop with the rule inside for accepting dport 443. When I set the DefaultCain to Drop I can't configure the Firewall anymore because it does not react.

Hi,

you also need to allow the localhost connection (see picture below).

if you also want to use the allow-list-method for the output chain you need this settings:
