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?
That sounds weird and super invasive…where is this?
They’re probably just using CGNAT.
It’s definitely not CGNAT. I have tested it using
traceroute.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”?
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.
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.
