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 ​https://www.virtualbox.org/wiki/Downloads
• Download putty from ​https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
• Download winrar from ​https://www.win-rar.com/download.html?&L=0
• Download Dynagen-dynamips and other required files
  • ​ext-Mirror or ​Lab-Mirror
• Download all server VM's
  • Pfsense ​Lab-Mirror
  • WinXp_Inside ​Lab-Mirror
  • WinXp_DMZ ​Lab-Mirror
  • Webserver ​Lab-Mirror
  • LibreNMS ​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=50000
sport=40000

Cable Connected

Adapter 3:

Attached to: Generic Driver
Name: UDPTunnel
Generic Properties:

dest=127.0.0.1
dport=50001
sport=40001

Cable Connected

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

• WINXP_INSIDE

Adapter 1:

Attached to: Generic Driver
Name: UDPTunnel
Generic Properties:

dest=127.0.0.1
dport=50003
sport=40003

Cable Connected

• WINXP_DMZ

Adapter 1:

Attached to: Generic Driver
Name: UDPTunnel
Generic Properties:

dest=127.0.0.1
dport=50002
sport=40002

Cable Connected

• Web Server VM

Adapter 1:

Attached to: Generic Driver

Generic Properties:

dest=127.0.0.1
dport=50004
sport=40004

Cable Connected

Install Dynagen other required tools

Extract the downloaded WKFiles.zip file to your C:\ drive. After extract Following files should be there.

Install Dynagen and WinPcap from extracted folder.It will install Dynamips as well and automatically creates the desktop shortcuts.

Files that are needed to run VPC Simulator are inside the VPC Files folder.

Dynagen is the front end of dynamips and we have to create campus network using a text editor. Network design for this workshop has already created for your convenience and named as Campus_Nw.net. This file is inside the LabFiles folder. You can edit the file by opening it using a text editor like notepad. The IOS Images that are required to run this network also inside the LabFiles folder. Steps for running this network will be discussed in next Network Setup session.

Configurations of Network Devices will be discussed in Network Setup session

Network design includes following Devices;

• 3 x EtherSwith Router
• 7 x Ethernet Switch
• 9 x VPCS

Host names of the devices are as follows,

• ESW1 :- FAC1
• ESW2:- FAC2
• ESW3:- FAC1-BLD1-FL2
• Ethernet switch-1:- FAC1-BLD1-FL1A
• Ethernet switch-2:- FAC1-BLD1-FL1B
• Ethernet switch-3:- FAC1-BLD2-FL0
• Ethernet switch-4:- FAC2-BLD1-FL1
• Ethernet switch-5:- FAC2-BLD2-FL1
• Ethernet switch-6:- FAC2-BLD2-FL3
• Ethernet switch-7:- DMZ

Use Following tutorial on Dynamips to understand how to create a simple network using Dynagen.

The following diagram shows the Network devices and connections that are already created in the Campus_Nw.net file.

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.
