I looked at the log on my router and I noted alert messages concerning UDP and internet addresses.
I decided to sniff the traffic (with wireshark) and highlighted DHT-protocol/UDP packets. The links/sockets are between external addresses and my router.
My bittorent tool (Deluge on windows) is not active but these links are still established: in fact they never close.
Is it possible to kill/stop/cancel/desactivate these links because they overload the firewall of my router ?
