OPNsense is an open source firewall and routing platform that can be used to secure network traffic. In this tutorial, we will be explaining how to install OPNsense on Arch Linux.
Download the latest version of OPNsense from the official website https://opnsense.org/.
$ wget https://opnsense.cdn.surftown.com/releases/21.7.1/OPNsense-21.7.1-OpenSSL-nano-amd64.img.bz2
Once you have downloaded the image, extract the contents using the following command:
$ bzip2 -dkv OPNsense-21.7.1-OpenSSL-nano-amd64.img.bz2
Insert the USB stick that you want to use for the installation.
To check the device name of the USB stick, run the following command:
$ lsblk
In our case, the device name is /dev/sdb. Make sure the device name matches your USB stick.
Next, run the following command to write the OPNsense to the USB stick:
$ sudo dd if=OPNsense-21.7.1-OpenSSL-nano-amd64.img of=/dev/sdb bs=1M status=progress
This process might take a while.
Once the USB stick is prepared, reboot your system and select the USB stick as boot media from the BIOS or UEFI settings.
After booting from the USB stick, you should see the OPNsense installation screen. Select the “Install” option to start the installation process.
Follow the on-screen prompts to complete the installation process.
Once the installation is complete, remove the USB stick and reboot the system. OPNsense should now be installed on your Arch Linux machine.
In this tutorial, we have explained how to install OPNsense on Arch Linux. We hope this tutorial helped you in your quest to secure your network traffic.
