Windows firewall setup?

Question

Windows

So the question is how does the windows firewall block or allow incoming or outgoing connections if a) the rule is forbidden ("obviously blocking") b) allowed ("clearly it allows here") c) (not set - "that is, it is not in the list of connections then it blocks all other traffic by default? and another question is why some connections are not marked with any sign (just white)? there are no rules defined for them?
ps as far as I know, windows firewall by default blocks all connections that are not in the list?

Answer 1

if the rules are not set as in my example simply ("white void") then how will I know how the firewall handles them? whether he passes traffic or not, that's the catch

there is no hitch, it is customizable as you choose. But this is difficult: you need to gather your will into a fist, take a deep breath and make a couple of mouse clicks (it’s twice as easy to see the state - just one click is enough).
