11 Thanks guys. The AP has a reserved static LAN IP address on the router
12 (10.10.10.13). It also has a MAC. So it is simply a matter of forwarding
13 (all) ICMP echo-reply packets that arrive from the Internet to that LAN
14 address. (On this implementation the AP is itself a Linksys wireless router).

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