A NAT address or series of addresses looks like an internal network to
systems on the outside network. Say we have a pool
of NAT address 1.1.1.1 thru 1.1.1.64 configured on the outside interface of
the router. System on the outside that want to communicate with these
addresses first requests a route to network 1.1.1.0. The outside system
should not attempt an ARP since they are not on the 1.1.1.0 segment. The
router replies with a "send it to me, I'm the gateway for the 1.1.1.0
network". The sending station on the router's network segment then requests
the hardware address of the router using ARP.
I haven't tested this but I believe the router would also respond to an ARP
for any address in the pool with its own hardware address as well.
Go NAT examples and help are available on the Cisco web site. www.cisco.com
