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?

      Ipv4 shortage lead to a lot of IPS adopting CG-NATs where they are sharing one exit IPv4 for multiple end users and that’s why opening a port on the end user side won’t do a thing as your just opening a port in the ISP Network and not to the Internet

      Who says the ISP isn’t blocking ports via a firewall?

      I thought it was common practice for ISPs to block certain ports for residential connections?

        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.
