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?
If the firewall just means no incoming connections, your computer can still reach out to the other side (if they open their port)
Right, only one side of the connection needs an open port (and most clients will let that be either seed or leech side)… this is why having an open port on your end is useful if you’re downloading, since you can download from seeders that don’t have an open port.
