Thanks guys.  The AP has a reserved static LAN IP address on the router 
(10.10.10.13).  It also has a MAC.  So it is simply a matter of forwarding 
(all) ICMP echo-reply packets that arrive from the Internet to that LAN 
address. (On this implementation the AP is itself a Linksys wireless router).

I wonder if I can play tricks with ping's ICMP headers to differentiate 
between them as they come into the router, or something clever that I haven't 
yet figured out.  Any ideas?
