I did install and run tcpdump then I realized that the answer was under 
my nose the whole time. The kernel log message gives the MAC address of 
the sending and receiving interface. After all this discussion, effort, 
and advice,  all I really needed to do was find the device with the 
sending MAC address. Which, as we suspected, was the wireless router. I 
still don't know why it doesn't NAT those particular packets, but in the 
big picture it doesn't really matter since they go nowhere.

The only question I have left is can I change a setting to disable the 
logging of these packets (or change their log level to debug)? There are 
literally thousands of them a day cluttering the log. If I have to I can 
filter them out using syslog but I'd prefer a cleaner solution.

Thanks for everyone's advice and effort.
