I find it very odd that you saw proxy arps replies from the router if it was
connected to your network by one of the LAN switch ports. Proxy ARP
usually only happens when you have a gateway device where the clients
do not have MAC access (PPP server), but the fact that the wireless 
client that alerted you to the presence of the router was using an address 
from your DHCP pool shows that there was in fact MAC access for the client.

Odd.
