Can anyone please test this for me(if you are behind a router and you have another pc to make this test plausible): Set Network Security to High, and see after that if you see other pc in Network or if your computer is visible from another pc, I ask this because I have the suspicion that after you set Networks Security to High(from Privatefirewall UI), your pc is still visible over the network, when normally Privatefirewall should block this. Thank you!
