At the beginning of this chapter, we showed a sample architecture that the author has encountered on a number of recent events. Throughout this chapter, we reviewed and conducted the process for building your range; moreover, we looked the layers of a range to emulate a number of different potential architectures that you may encounter throughout your testing. Having said that, you may have noticed that our diagram has two firewalls and Bastion Hosts, but we have only built one; therefore, this is your challenge: to build the second firewall Bastion Host Two. Your challenge is as follows:
Select a firewall for your machine; there are a number of choices available, and you are free to select the one that works best for you
Build the interfaces, and connect machines to your firewall
Configure the rules and route traffic through the two firewalls; as a reminder, the routing is the key here
This challenge will allow you to continue to practice the skills we discussed in this chapter...
