I'm not so sure. If you're correct in saying that the wrouter is
NATing, then the packets it sends out would have its IP address and MAC
no matter which wireless system they came from. Also, if you're getting
thousands of them per day, I wonder if this is *all* of your wireless
In your TCPDUMP, do you see any traffic at all to and from
192.168.0.100, the IP you think the wrouter is using ? If not, then
it's possible the wrouter isn't using it at all.
Check the wrouter config and see if 192.168.3.2 has any significance.
Is it the router itself ? The DNS server ? Or is it one of the
DHCP-assigned addresses ? If so, what system has it ?
