Hi Guys, I have just had a look at my Router settings from 192.168.0.1 and it shows multiple DoS (Denial Of Service) Attacks from different IP's.

Code:

I do not have much experience with Routers/Networks, so I need help blocking these or removing them.

I have a NETGEAR DGN1000SP Router with Virgin Media 10MB/s Internet.

I have 1 Netbook, 2 PC's and a iPhone. But I only use 1 PC and my iPhone. My family uses the other 2 computers.

I have installed MSE, Malwarebytes, and Comodo Firewall on the Netbook and 1 PC. Have not done it to the other PC yet, and I don't really need to do anything to my iPhone.

The first thing you need to do is contact your ISP as their servers may have been compromised.

Virgin Media should help and advise as to what you can do, but you may have to upgrade your hardware.

Have a look at this article, which describes the different ways these DoS attacks work and possible solutions to get them stopped.

This Wiki article has loads of useful information too.

This is apparently not uncommon with Netgear routers. I suspect it is very common, but only Netgear routers are storing them as DOS attacks. They can be random port scans. I would think you will be protected by the NAT firewall in any case. I agree with seavixen32, ask your ISP about it, if they agree it is not an issue, I think you are ok. You could not prevent a DOS from your end anyway, that is a server/ISP issue. If they were being attacked, and their bandwidth compromised, they would be all over it. A Guy

You're very welcome.

Do let us know what they say as it'll be interesting to know if they take it seriously.
