[[Image:my-network.png|thumb|right|350px|Setting up networks is an essential operation for a system administrator. Maintaining network connectivity and securing the network are also essential operations. In this lab, we will '''configure a Virtual Private Network private virtual network using static IP addresses''' (eg. wired workstation connections). We will learn how to setup a DHCP network (eg. for notebook, table and smartphones) in lab 8.]]
===Purpose / Objectives of Lab 6===
<li value="1">Let's start with our '''centos1 VM'''. Double-click on your '''centos1''' VM, but instead of running the VM, click on the '''view''' menu, and select: '''Details'''<br />(Note: the Virtual Machine window will appear - do not start virtual machine)</li>
<li>In the '''left pane''' of the Virtual Machine window, select '''NIC:''' and note that this NIC is on the "default" virtual network</li>
<li>Change it to '''Virtual Network network1: NAT''' (i.e. the VPN network that you just created) and click the '''Apply''' button.</li>
</ol>
</li>
# When finished, check your settings, and then click the '''Apply''' button.
# Open a terminal and issue the '''ifconfig''' command to confirm the IP ADDRESS settings change.
# Verify that '''centos1'''VM is now connected to the VPN private network by issuing the following command from your '''c7host''' machine:<br><b><code><span style="color:#3366CC;font-size:1.2em;">ping 192.168.235.11</span></code></b>
[[Image:network-scripts.png|thumb|right|250px|Although you can use the '''ifconfig''' command to temporarily create a static IP address connection to a network, you need to add the network settings in the '''/etc/sysconfig/network-scripts''' directory to automatically connect to the network upon Linux system boot-up.]]
