The NAT and OpenSSH module provides you with the instruction and devices to develop your hands on skills in the defined topics. This module includes the following exercises:
- Installing NAT Firewall
- Installing OpenSSH
Lab time: It will take approximately 1 hour to complete this lab.
The following exam objectives are covered in this lab:
- SY0-501 2.1: Install and configure network components, both hardware- and software-based, to support organizational security
- SY0-501 2.4: Given a scenario, analyze and interpret output from security technologies
- SY0-501 3.2: Given a scenario, implement secure network architecture concepts
Exercise 1 - Installing NAT Firewall
Network Address Translation (NAT) is a feature included in Windows Server’s Routing and Remote Access Service or RRAS. NAT is used to connect multiple computers in a small private network to the Internet using a single public IP address provided by an Internet Service provider. The NAT server uses network interface connected to the Internet to process requests from internal computers by keeping track of IP addresses and port numbers that routed from the private network to Internet and vice-versa.
In this exercise, you will configure a device so that it performs Network Address Translation for an internal client to an external destination.
Exercise 2 - Installing OpenSSH
Port forwarding or port mapping is the process of redirecting a communication request from one IP address and port number to another while the data packets are passing through a router or a firewall. Port mapping is one of the capabilities built into Network Address Translation (NAT) feature in Routing and Remote Access Server.
In this exercise, you will set up NAT to configure port forwarding.
