Thanks Karma I'll see what I can find out

Hi, Thanks for your response, just a quick correction on your reply:

2009-11-19 09:50:53 - UDP Flood - Source:192.168.1.3
,57285,LAN - Destination:194.168.4.100,53,WAN

The destination is a 194 not a 192 subnet,

My external IP currently is 77.101.212.219

My Router primary DNS is 194.168.4.100 which matches the Destination address and its always port 53, which you would expect.

The router internal address is 192.168.2.1

DHCP is delivering an IP address range of 192.168.2.100 through 192.168.2.200

So it makes no sense to me, Could my router be compromised somehow?

Regards

Gordon

My internal network runs with a 192.168.2.x class C address range but my router (It's also the DHCP server of course) keeps emailing me the following message:

2009-11-17 19:53:00 - UDP Flood - Source:192.168.1.3
,58393,LAN - Destination:194.168.4.100,53,WAN

How come the source is 192.168.1.3?

The Destination is my ISP DNS server I guess

I hope someone can explain whats going on,

Gordon

P.S. I don't run an internal DNS Server.
