How to Install OPNsense on Fedora Server

OPNsense is an open-source firewall and routing platform that is based on the FreeBSD operating system. It offers robust security features and configurable options that make it a popular choice for small businesses and individuals. If you want to install OPNsense on Fedora Server, you can follow these steps:

Step 1: Download the OPNsense Image

The first step is to download the OPNsense image from the official website.

1. Go to https://opnsense.org/download/
2. Select the mirror closest to you, in case the page doesn't load due to server routing issue, you might need to try multiple locations.
3. Click on the AMD64 link under the OPNsense-XX.X-OpenSSL-dvd-amd64.iso.bz2 section

Step 2: Verify the OPNsense Image

After downloading the OPNsense image, it's a good idea to verify its integrity to ensure that it hasn't been tampered with.

1. Download the SHA256 file from the same mirror site where you downloaded the ISO file for OPNsense.
2. Verify that the SHA256 value of the downloaded OPNsense image matches the one listed on the site.

Step 3: Create a Bootable USB Drive

Once you have downloaded and verified the OPNsense image, you can create a bootable USB drive to install OPNsense on your system.

1. Insert a USB drive into your computer.
2. Convert the .iso file to .img with command: sudo dd if=/path/to/OPNsense-XX.X-OpenSSL-dvd-amd64.iso of=/dev/sdX bs=4M status=progress && sync
3. Replace /path/to/OPNsense-XX.X-OpenSSL-dvd-amd64.iso with the location of the downloaded OPNsense image, and /dev/sdX with the device name of your USB drive.

Step 4: Boot from the USB Drive

After creating a bootable USB drive, you can now boot your system from it to start the installation process.

1. Insert the USB drive into the system where you want to install OPNsense.
2. Reboot the system and enter the BIOS menu by pressing the appropriate key. (Usually F12, F10 or F2)
3. Select the USB drive as the primary boot device, and save your changes.
4. Hit Enter to start the installation process.

Step 5: Install OPNsense

After booting from the USB drive, you can start the installation process by following the prompts on the screen.

1. Select "Install OPNsense" when prompted, and press Enter.
2. Choose the hard drive where you want to install OPNsense and select "OK".
3. Follow the prompts to configure your network connection and set up your OPNsense installation.
4. Once the installation is complete, remove the USB drive and reboot your system.
