LAB 01 : Environment Setup - Zacham17/my-tech-journal GitHub Wiki

Brief Summary

In this environment setup lab, I configured a firewall virtual machine and a workstation virtual machine along with network adapters to use with them.

Notes

  • This was the first time using cyber.local to connect to virtual machines, so doing that in this lab will prove useful to me in the future.
  • PfSense is a firewall that provides routing services between a Local Area Network and Wide Area Network
    • PfSense has the following options:
  • I used the "Assign Interfaces" and "Set Interface(s) IP Address" options for this lab
  • I also used the "Shell" option to execute commands.
  • I configured a LAN interface and a WAN interface
  • I then configured the wks01 virtual machine to connect to the PfSense Firewall using the ICMPv4 properties of the network interface and did some setup via the web interface for the firewall.

New Terms/Steps

  • In this lab, I used PFSense and a text-based user interface to configure the network adapters on the fw01 Virtual Machine. I thought this was good to practice as it is important to know how to configure settings in both a graphical and text-based user interface.
  • In this lab, the term “upstream gateway” was used multiple times. After some quick research, I learned that an upstream gateway falls under the category of a default gateway, but it is given a higher priority in being chosen than other possible default gateways.
  • In this lab, I used the -h option with the tracert command. Using the -h option is very helpful in making a tracert output more manageable and could help isolate any issues you may be trying to find.
  • A new term in this lab was "RFC1918 Networks", which I learned are private networks that cannot be reached from the internet.
