The problem with that is that the firewall rules on these boxes
immediately log and drop any packet that doesn't come from the subnet
assigned to that interface. I'm not an expert on iptables but I believe
that anything coming in on those interfaces would hit iptables and be
dropped before the kernel log. Even if the kernel saw them first I
should still see corresponding iptables log entries. The router boxes
don't have any wireless cards so they aren't generating these entries
that way. I don't know how a wireless host connecting to a wireless
router, which has a wired LAN IP on LAN facing interface and uses DHCP
for the wireless interface, is able to propagate a different IP address
all the way to the firewall without being translated or dropped. Very
