I am using qbittorrent for torrenting and my ISP has refused to open up firewall because of fucking "security" reasons. however I can still seed the torrent how is that possible? I mean all the incoming connections should be blocked right? isn't it how firewall works?
Except that no good VPN does this anymore (I believe Mullvad was one of the last to pull the service and cited massive headaches due to CP violations). So if you find one that does, it's most likely pretty sketch or just not that secure.
Yes, ProtonVPN still provides port forwarding. They randomly assign you a single port every time you connect, so you'll have to update the settings in qB occasionally, but it's manageable.
