UDP flood?

[Millie!]

Recently when I open Utorrent, my download speed shoots up and then crashes and stays at 0-1kb/s, which also stops my access to the internet on firefox as well. As soon as I exit Utorrent it starts to work again.

Part of my security log:

I've had a look at some other threads but didn't really understand a lot of it. I've disabled UPNP, NAT-PNP, DHT and local peer discovery, however it's still not working properly. Also I read about IP-resolve but couldn't find this option?

I read on here that you should change the ping detection on the router so I disabled ICMP ping - as this was the only feature that seemed similar!

Also even before this was happening, the speed of my downloads used to fluctuate - it would drop to 0 and then go back up every so often and my internet wouldn't work when that happened.

Sorry for being pretty clueless - I appreciate your help.

IP resolving is in Peer tab: right click and disable it.

If you've set uTorrent's settings too high, the resulting overloads can mimic firewalled conditions.
