Hi,
I have a D-link router on Virgin media cable (UK). Connected to this, my
laptop on which runs PCguard on which I found the following log entry :

tcp Incoming 216.89.80.51 80 192.168.0.8 4754 21/12/2007 17:43:26

I've not got the router set up to send anything incoming to this laptop so
why is there incomming traffic ?

When I http://216.89.80.51 I get :

<af>
<r c="ok"/>
</af>

Thanks in advance.

Bruce.

Counter question: Why do you expect that there should be no incoming traffic?

The incoming IP is on the NET, not the LAN and I've not got the router set
to forward any traffic from the WAN to this computer.

And why do you think that explicit forwarding is the only way the router may
forward traffic?
