If you forward a port on your network (or VPN) and point your torrent software towards that port, you are now an “active” node. You can communicate with anyone else, forwarded or not.
If you leave it closed (passive node), you can only communicate with active nodes. With large torrents, this isn’t an issue because there’s more than enough active nodes to send the data.
Port forwarded: talk to anyone, even closed
Port closed: only talk to port forwarded people and hope that small torrents have someone with a forwarded port.
If you don’t have port forwarding and the seeder doesn’t then you won’t see them.
A lot of casual torrent users won’t know about this so it’s a common issue on public trackers.
Did you mean if there is no port forwarding at my end and also at seeder’s end ?
Could you elaborate? Never heard of this aspect

Thank you. Does this create any considerable vulnerabilities?
