I seem to be getting a lot of DOS attacks according to my Router (Netgear DGND3700v2) logs, which in turn (I think) is making the internet very slow and even timing out nearly all webpages I get to.

I even tried tracing one of the IP addresses and it came back saying it was from Symantec in the US! 

How do I stop these?

Here are a sample of them:

Probably just your router giving false alarms, my old netgear used to do the same from time to time. Half those IPs in the list are Akamai anyway

This is the first time it has ever happened to me. After this just started, most of the web pages are timing out, or are very very slow to get to.

I've just tried Posting this a few times but it kept saying "web page unavailable".

sonyxperiageek: This is one of the IPs: http://whatismyipaddress.com/ip/111.221.124.25


 looks to be windows update.

none of these logs appear to be legit.

Any "scan" type activity should be classed as Reconnaissance.  The fact your router classes it as DoS just shows what a sad joke the security in consumer grade routers is.

If you had a DDOS attack, your internet connection would pretty much be unusable, and your gigabyte data usage counter would be through the roof

One of our customers' kids was in an online game and kept winning against some foreign player. He threatened to launch a DDOS against our customer's ip address - and the kid kept antagonising him. So off he went, rented a botnet and we had something like 50mbits of pings coming in over about half an hour.
Told the kid next time someone threatens a DDOS attack, he either walks away or he can find a new ISP.

It was pretty unusable back at the time which is why I posted this in the forums. Now it seems fine, internet is back to normal speeds.
