Router reports DOS attacks

Hi guys

Have been using Utorrent for ages, no problems, love it.

Upgraded to Version 2 yesterday.

I happened to view my router log and found something a little odd.

With Utorrent open, but with no active torrents, my logs look like this......

Wed, 2010-02-24 13:35:33 - UDP Packet - Source:83.243.187.26,63720 Destination:xx.xxx.178.90,61454 - [utorrent rule match]

Have removed some of my ip address, please excuse my paranoia.

Once I activate a torrent however, my logs look like this.......

My pc is indeed at 192.168.0.2 and Utorrent is currently on port 61454.

Router is Netgear DG834G.

I can upload and download with no problems.

Is this something I should be concerned about?

Is there anything I can do about it (other than not haver active torrents that is).

Cheers

Broken-by-design router by the sound of it.

Disable Stateful Packet Inspection (SPI - also known as hardware firewall) in the router.

It's too paranoid for its own good.

I take it that means you think I can safely ignore these error messages as they are erroneous?

Thanks for getting back to me.

Basically. You'll probably get better performance out of the router if you turn off its attack detection features, considering it doesn't really -do- anything.

Would rather not turn off the router firewall.. You can never be too paranoid on the web.

Disabled DHT in UTorrent and the problem has stopped.

Actually, you can. the NAT system of a router absorbs the traffic using less router resources than the router's secondary firewall.
