+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 
+traffic.
+
+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 ?
