It's just a hunch, but it looks like your wireless router thing is doing SNAT
/Masquerade for its wireless hosts, even though the address is routable it 
is still changing thier source ip's to be it's own, 

this is what you would expect for the default on an average out of the box 
wireless router as many people will just plug it into the cable modem and 
expect the net to magically work.
