Connecting Kalilinux to Internal Network with Pfsense Firewall using VirtualBox: Troubleshooting Home Router Dashboard Issue

Connecting Kali Linux Internal Network to pfSense Firewall using VirtualBox: Troubleshooting Home Router Dashboard Issue

In this article, we will discuss the steps to connect the Kali Linux internal network to a pfSense firewall using VirtualBox, and troubleshoot the issue of the home router dashboard opening instead of the pfSense dashboard. We will cover the key concepts and provide detailed context on the topic, including subtitles, paragraphs, and code blocks as needed.

Setting up the pfSense Firewall in VirtualBox

The first step in connecting the Kali Linux internal network to the pfSense firewall is to set up the pfSense firewall in VirtualBox. This can be done by creating a new virtual machine in VirtualBox and selecting the pfSense installation media. Once the virtual machine is created, it can be configured with multiple network interfaces, including a WAN interface connected to the home network and a LAN interface connected to the Kali Linux internal network.

# pfSense network configuration
WAN_IF=em0
LAN_IF=em1

Configuring the Kali Linux Internal Network

Once the pfSense firewall is set up and configured, the Kali Linux internal network can be configured to connect to the pfSense LAN interface. This can be done by creating a new virtual network interface in VirtualBox and configuring it to use the pfSense LAN IP address as the default gateway. The Kali Linux network configuration can then be updated to use the new virtual network interface as the default route to the internet.

# Kali Linux network configuration
auto eth1
iface eth1 inet dhcp
    post-up route add default gw 192.168.1.1
    pre-down route del default gw 192.168.1.1

Troubleshooting the Home Router Dashboard Issue

If the home router dashboard keeps opening instead of the pfSense dashboard, there are a few troubleshooting steps that can be taken. First, it is important to ensure that the Kali Linux internal network is correctly configured to use the pfSense LAN IP address as the default gateway. If the gateway is set incorrectly, the Kali Linux system may default to using the home router instead of the pfSense firewall.

Another potential issue is that the pfSense firewall may be blocking access to its dashboard from the Kali Linux internal network. This can be checked by logging into the pfSense web interface and verifying that the firewall rules allow traffic from the Kali Linux internal network to the pfSense dashboard. If the rules are not set up correctly, they can be updated to allow traffic from the Kali Linux internal network.

Connecting the Kali Linux internal network to a pfSense firewall using VirtualBox can provide a secure and isolated network environment for penetration testing and security assessments. By following the steps outlined in this article, you can set up and configure the pfSense firewall and Kali Linux internal network, and troubleshoot any issues that may arise, such as the home router dashboard opening instead of the pfSense dashboard.
