DoS attacks

  f1fan 10:25 06 Jun 2004

I’ve recently purchased a Netgear DG834 router to share my broardband internet connection and files between my 2 PC’s at home.
I have configured the router to e-mail me due to large amount of ‘DoS attacks’ I appear to receive. These attacks also happen at night when no computer is switched on.
Question: is this normal or am I being targeted?
Should I switch the router off then not in use?

I have list below some typical examples.

Fri, 2004-06-04 12:37:19 - TCP Packet - Source:,4097,3127 - [DOS]
Fri, 2004-06-04 16:17:29 - TCP Packet - Source:,4111,1025 - [DOS]
Fri, 2004-06-04 16:17:29 - TCP Packet - Source:,4114,6129 - [DOS]
Fri, 2004-06-04 16:17:29 - TCP Packet - Source:,4107,2745 - [DOS]

I thought it would be a good idea to omit my IP address.

Please explain 'dynamically assigned'

You are not being attacked. The traffic comes from BT OpenWorld (your ISP). The server is checking that you are connected.
