Introduction

Setting up a lab environment for networking and cybersecurity testing can be a complex process. In this article, we will discuss common issues and solutions when configuring a pfSense firewall running on VirtualBox, hosted on a Windows laptop (Laptop 1), and connecting another laptop (Laptop 2) to it.

Lab Setup

The following is the lab setup for this article:

Laptop 1: Host for VirtualBox with pfSense installed
Laptop 2: Client connecting to pfSense via Ethernet

Running Issues

The main issue we will be addressing in this article is when Laptop 2 cannot pull an IP address from pfSense running on VirtualBox hosted on Laptop 1.

pfSense on VirtualBox

pfSense is a popular open-source firewall that can be run on a virtual machine. In this case, we will be running pfSense on VirtualBox, a popular virtualization software.

Connecting Laptop 2

Laptop 2 is connected to pfSense via an Ethernet cable. However, Laptop 2 is not able to pull an IP address from pfSense.

Solutions

The following are some potential solutions to this issue:

Check Network Adapter Settings

In VirtualBox, make sure that the network adapter settings for pfSense are set to Bridged Adapter. This will allow pfSense to communicate with other devices on the network, including Laptop 2.
