Hello,
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?
They will usually block port 25 so you can’t run a mail server. It’s unusual for an ISP to block everything unless you are on CGNAT.
