How to add public IP address pools to our NAT server?

Start -> Programs -> Administrative tools -> RRAS -> IP routing -> click on NAT -> on
Right hand side you see network cards -> click on external NIC (which has a valid public IP) -> Click on Address pool tab -> Click on add button -> Give the pool of IP addresses.
Note: By default there is no access to the internal devices on the NAT network to out side clients. By default out side clients cannot access any thing in our Nat network.
