Overview

Introduction

The Configuring Routing and Network Address Translation module provides you with the instruction and server hardware to develop your hands-on skills in the defined topics. This module includes the following exercises:

  • Preparing System Requirements for RRAS
  • Installing the RRAS and Enabling LAN Routing
  • Configuring Network Address Translation

Exam Objectives

The following exam objectives are covered in this lab:

  • Implementing Network Address Translation
  • Configuring Routing

Exercise 1 - Preparing System Requirements for RRAS

The Routing and Remote Access Service (RRAS) provides an interim solution for small organizations to enable remote connectivity with the use of services like dial-up and virtual private networks (VPNs) for mobile users. In addition, the RRAS functions as a software-based router that can route traffic in a LAN environment that has more than one network subnet. For a branch office that requires shared internet access, the RRAS has a Network Address Translation (NAT) feature, which translates an internal IP to a public IP and hides internal network settings from outside users.

In this exercise, you will prepare the devices that will be required to successfully implement LAN routing and Network Address Translation (NAT) in the next set of tasks.

Exercise 2 - Installing RRAS and Enabling LAN Routing

Like other Windows features, the Routing and Remote Access Service (RRAS) can be installed either by using the Server Manager > Dashboard window or by using Windows PowerShell. In this exercise, you will install the RRAS via the command line in order to minimize the number of steps involved in adding a Windows feature. Thereafter, you will configure the LAN routing feature in the Routing and Remote Access console.

Exercise 3 - Configuring Network Address Translation

Network Address Translation (NAT) is a routing protocol included in Windows’ Routing and Remote Access Service that provides shared internet access for departmental local area networks. Typically, a NAT server is fitted with two network interface adapters: one connected to the internet, and the other facing the internal network. Client workstations are configured to use the NAT server as their default gateway, which enables these devices to request resources from the internet.

When a NAT server receives a request to access an external resource, it redirects the traffic from its interface (using a private IP) to the other interface (using a public IP) and connects to the internet resource
