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, 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 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 ?
