[c-nsp] cisco ip nat question

[Mike]

Hi,


     I have a bunch of dumb devices that don't know how to deal with a 
default gateway. They all live in a subnet 172.16.144.0/20.

     A router lives here @ 172.16.144.1, and my device management 
station lives on another network, say 10.0.1.0/24.

     What I think I want, is for packets going from my management 
station to the dumb devices to be source ip natted so that they appear 
to come from the router itself 172.16.144.1, so that any devices on the 
172.16.144.0/20 network that can't understand default gateway, can at 
least respond since the source address they will see will be the router 
itself and within their same subnet.

     How would this be accomplished? Is it as simple as putting 'ip nat 
inside' on the interface facing the dumb devices? Or is there more to it?

Mike-
