Throughout this chapter, we identified a number of methods of creating multiple layers of a network architecture, but one thing we did not do is explore the connection of our two bastion hosts. Your challenge is as follows:
Taking the networks and machines you have created in this chapter, connect all of them together and perform testing using the techniques we discussed in the chapter. That is, connect the two bastion hosts and their corresponding segments together.
Add additional adapters to the Network Security Toolkit machine, and monitor different switches of the network.
Explore the options for adding different packages to the pfSense firewall. You can add IDS, Web Application Firewall, and so on. Explore and have fun!
This challenge will allow you to experiment with the different components and building blocks of expanding your range, and this will allow you to test a number of different possible environments that you may encounter.
