Lab Setup

In this Hands-on we will install all dependencies and basic network design. We will use Oracle Virtual Box and Dynagen-Dynamips software to virtualize the lab network.

Users need to connect the host PC to home network with DHCP enabled. We recommend using the wired network as much as possible.

For each User following software and files are required;

• Needs to install Dynapimps-Dynagen , VPC PC simulator and Virtual Box
• pcap and cygwin1.dll

We will create a entire virtual network on host machine.

Virtualized appliances will be connected via UDP tunnels and these must be neglected for your actual physical installations.

Download Dependencies

• Download Oracle Virtual Box from ​here
• Download pfsense VM from ​ext-Mirror or ​Lab-Mirror
• Download Required router images
  • ​ext-Mirror or ​Lab-Mirror
• Download Dynagen-dynamips and other required files
  • ​ext-Mirror or ​Lab-Mirror
• Download all server VM's
  • GUI_XP ​ext-Mirror or ​Lab-Mirror
  • LibreNMS ​ext-Mirror or ​Lab-Mirror

Following settings will need to be as it is with the changes only to the specified dynamic content.

Install Virtual Box

Install Virtual Box software with default settings, make sure you have enabled virtualization support from your host machine BIOS.

If you have pre-installed Virtual Box in your host machines make sure they are updated to 6.x latest version

Import downloaded OVA files into Oracle virtual box from File > Import Appliance

While importing make sure to select Generate new MAC addresses for all Network Adapters from MAC Address Policy.

As soon as you import vm's, change your VM network connections as follows;

• pfSense VM

Adapter 1:

Attached to: Bridged Adapter
Name: [[Your Physical Adapter Name]]
Promiscuous Mode: Allow All
Cable Connected

Adapter 2:

Attached to: Generic Driver
Name: UDPTunnel
Generic Properties:

dest=127.0.0.1
dport=30000
sport=20000

Cable Connected

Adapter 3:

Attached to: Generic Driver
Name: UDPTunnel
Generic Properties:

Note down all mac addresses as we need them to decide which port connects to which network later when installing pfsense)

• GUI_XP VM

Install GNS3

On host machines, install Dynagen package from previously downloaded files.It will install Dynamips as well and automatically creates the desktop shortcuts.

On first application load, cancel all wizards including Open Project wizard.

Go to Edit --> Preferences

• Select Server on Left side menu and select Enable local server from Main Server tab if it is not selected already.

• Click Apply

• Select Dynamips --> IOS routers on Left side menu and New
  • Select New Image and Browse to the router image file you downloaded.
  • Select yes for the window Would you like to decompress this IOS image.
  • On the Next step, tick the option called This is an EtherSwitch router and click next.
  • Keep all other settings to their default values and click next till the last option Idle-PC
  • Click Idle PC finder and wait for a moment. Once it finds a value click finish

• Click Apply and Ok

Next go to File --> New blank project

• Name the project as Campus Network and click OK

---

On your new project click on the fifth icon on your left corner menu Browse All Devices

Drag and drop following devices into the design area

Then as per the given network diagram, connect your devices. Make sure you connect ports exactly as per the diagram.

Please note that the link between pfSense and the LEARN Router nodes are for illustration purposes only. You are not allowed to connect them via connections as both of them are cloud devices. As we are directly using a bridged interface for pfSense WAN, you may use a "Drawn line" to complete the diagram.
