uTorrent uses port 53 and UDP - how to turn off?


Recommended Posts

UDP is used by uTorrent for uTP connections (in latest v1.8.x and v1.9), IPv6 (if IPv6 is natively available OR Teredo is running), DHT, and Resolve IPs. All of that can be disabled if so desired though uTorrent's performance may suffer (or improve if on marginal networking hardware/software.)
