NAT question

Is it advisable to use windows NAT inside a network where there is a
NAT router ? my purpose is try to cache all the queries before it
reaches my hardware router and to reduce my network traffic. Pls advise
thanks.

A proxy server would be a better idea for that sort of thing.

To expand a bit, caching requires that the client be aware of the
situation. With NAT, the client is not aware that it is behind a NAT. It
behaves as if it has a direct connection and sends its requests to the
"external" addresses. NAT translates the requests.

With a proxy server, the client is aware of the proxy server. It sends
its requests to the proxy server. The proxy server does the external queries
on its behalf and caches the replies.

"Natting" doesnt cache anything, its just for 'address translation"
from one to another e.g. internal and external networks.
if you want to cache traffic - depending on what kind of traffic it is
( web traffic e.g.) a sort of proxy server does the job

to expand a bit more,

there are situations where the client actually is NOT aware of a proxy
server - regardless, the proxy knows when another client requests
something thats already in its cache, so it does not have to look for
it again, it just sends the cached data back to the client.....thus
saving network load/traffic
