This allows multiple computers to share the same Internet connection. With Windows
Server 2008, you can accomplish the same thing using RRAS. NAT in RRAS can even
distribute IP addresses to whichever interface you designate as your private interface, so
that connectivity can be established quickly and easily. Configuring the DHCP allocator
can be done from the NAT Properties window under the Address Assignment tab, as
shown in Figure 11-17.
Hands-On Exercise: Installing and Configuring NAT
In this exercise, we install the NAT routing protocol. We will configure one network interface
as an external interface and another network interface as a private interface. We
will allow connectivity from hosts communicating through the private interface to the
external interface by NATing their addresses to the external IP address.

NOTE As with all routing services, you will need to make sure you have two network interfaces
(excluding Internal or Loopback) for this to work.
1. Install the NAT routing protocol by following the exercise for installing RIPv2,
except select NAT instead of RIPv2 for IP.
2. In the Routing and Remote Access management console, expand your server,
then IPv4, and then right-click NAT and select New Interface.
