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're probably just using CGNAT.

That's not a firewall though, which is what OP mentions.

Does OP really know exactly what technology at his ISP is preventing him from "opening ports"?

[-] Grippler@feddit.dk 6 points 6 months ago

Maybe not, but you and I definitely dont, so let's stick to what they're actually saying instead of guessing.

You commented that it's "super weird and invasive" for an ISP to "firewall" listening ports. It just so happens that CGNAT also has the same effect and is super commonly used right now.

I think I'm good 👍

Yes I know what's preventing me from opening ports. I also called my ISP they said we can't open the firewall so the incoming connections will be blocked.
