How to install OPNsense on Void Linux

Introduction

OPNsense is an open-source, easy-to-use and easy-to-build FreeBSD-based firewall and routing platform. This tutorial will guide you through the process of installing OPNsense on your Void Linux system.

Prerequisites

Before you begin, you will need:

• A Void Linux system installed and configured
• Root access to the system
• Internet access

Step 1: Download the OPNsense image

1. Go to https://opnsense.org/download/ and download the latest OPNsense image.
2. Choose the "AMD64" architecture and "USB Memstick Installer" as the installation medium.
3. Once the download is complete, extract the .img file from the downloaded archive.

Step 2: Prepare a USB drive

1. Insert a USB drive into your system.
2. Use the lsblk command to identify the device name of your USB drive. For example, if your USB device is /dev/sdb, then the device name is sdb.
3. Open a terminal and run the following command, replacing /dev/sdx with the device name of your USB drive:

dd if=/path/to/opnsense.img of=/dev/sdx bs=4M && sync

This command will write the OPNsense image to your USB drive.

Step 3: Boot from the USB drive

1. Restart your system and enter the BIOS/UEFI settings.
2. Ensure that the USB drive is set as the first boot device.
3. Save the changes and exit the BIOS/UEFI settings.
4. The system should now boot from the USB drive.

Step 4: Install OPNsense

1. Once the OPNsense installer has loaded, select "Install" from the menu.
2. Choose your language and keyboard layout.
3. Select the disk where OPNsense should be installed.
4. Choose the "Guided" installation method, which will automatically partition the disk.
5. Confirm the changes and begin the installation.
6. Once the installation is complete, eject the USB drive and reboot the system.

Conclusion

Congratulations! You have successfully installed OPNsense on your Void Linux system. You can now log in to the web interface using the default username "root" and password "opnsense".
