Downloading the pfSense 64-bit ISO

Okay, now for the main event: downloading the pfSense 64-bit ISO. This is a super simple process, but let's walk through it step by step to make sure you don't miss anything.

Head to the Official pfSense Website:
- Open your favorite web browser and go to the official pfSense website: https://www.pfsense.org/download/
Configure Your Download Options:
- On the download page, you'll see several options that you need to configure. Let's break them down:
  - Architecture: Make sure to select "AMD64" for the 64-bit version.
  - Installer Image: Choose the appropriate installer image based on your needs. The "DVD Image (ISO) Installer" is generally the best option for most users, as it allows you to install pfSense from a bootable USB drive or DVD.
  - Mirror Site: Select a mirror site that's geographically close to you. This will ensure the fastest download speeds.
Start the Download:
- Once you've configured all the options, click the "Download" button. Your browser will start downloading the pfSense 64-bit ISO file. The file size is usually around a few hundred megabytes, so it might take a few minutes to download depending on your internet connection speed.
Verify the Download (Important!):
- After the download is complete, it's crucial to verify the integrity of the ISO file. This ensures that the file hasn't been corrupted during the download process and that it's safe to use. The pfSense website provides checksums (MD5, SHA256) for each ISO file. You can use a checksum utility to calculate the checksum of your downloaded ISO file and compare it to the checksum provided on the website. If the checksums match, you're good to go. If they don't, you'll need to download the ISO file again.

Creating a Bootable USB Drive

Now that you have the pfSense 64-bit ISO, you need to create a bootable USB drive from it. This will allow you to boot your computer from the USB drive and install pfSense. There are several tools available for creating bootable USB drives, but one of the most popular and easy-to-use is Rufus.

Download Rufus:
- Go to the Rufus website (https://rufus.ie/en/) and download the latest version of Rufus.
Run Rufus:
- Once the download is complete, run the Rufus executable. You don't need to install it.
Configure Rufus:
- In the Rufus window, configure the following settings:
  - Device: Select your USB drive from the dropdown menu. Make sure you select the correct drive, as this process will erase all data on the selected drive.
  - Boot selection: Select "Disk or ISO image (Please select)" and then click the "SELECT" button to browse to your downloaded pfSense ISO file.
  - Partition scheme: Select "MBR" for older systems or "GPT" for newer systems. If you're not sure which one to choose, try "MBR" first. You can usually determine this from your BIOS settings.
  - Target system: This should automatically be set based on the partition scheme you selected.
  - File system: Select "FAT32" for MBR or "NTFS" for GPT.
  - Cluster size: Leave this at the default value.
  - New volume label: You can give your USB drive a name, such as "pfSense".
Start the Process:
- Click the "START" button. Rufus will warn you that all data on the USB drive will be erased. Confirm that you've selected the correct drive and click "OK" to continue.
Wait for Completion:
- Rufus will now create the bootable USB drive. This process might take a few minutes. Once it's complete, you'll see a "DONE" message in the Rufus window.

Installing pfSense

With your bootable USB drive ready, you're now ready to install pfSense on your hardware. The installation process is fairly straightforward, but here are some key steps to guide you:

Boot from the USB Drive:
- Insert the USB drive into your computer and restart it. You might need to enter your BIOS settings to change the boot order and prioritize booting from the USB drive. This is usually done by pressing a key like Delete, F2, F12, or Esc during startup. The key to press varies depending on your motherboard manufacturer, so consult your motherboard's manual if you're not sure.
Follow the On-Screen Instructions:
- Once your computer boots from the USB drive, you'll see the pfSense installer. Follow the on-screen instructions to install pfSense. The installer will guide you through the process of partitioning your hard drive, configuring network interfaces, and setting up basic firewall rules.
Configure Network Interfaces:
- During the installation process, you'll be prompted to configure your network interfaces. This is a crucial step, as it determines how pfSense will connect to your network. You'll need to identify which network interface will be your WAN (Wide Area Network) interface, which connects to the internet, and which interface will be your LAN (Local Area Network) interface, which connects to your internal network. Usually pfSense detects this automatically. If not, you may need to manually specify your interfaces.
Set the Admin Password:
- After the installation is complete, you'll be prompted to set the admin password for the pfSense web interface. This password will be used to access the pfSense web interface and manage your firewall. Choose a strong and unique password to protect your network from unauthorized access.
Access the pfSense Web Interface:
- Once the installation is complete and the admin password is set, you can access the pfSense web interface from any computer on your LAN. Simply open a web browser and enter the LAN IP address of your pfSense firewall. The default LAN IP address is usually 192.168.1.1, but it might be different depending on your configuration. You'll be prompted to enter your admin username and password. After logging in, you'll be able to configure all aspects of your pfSense firewall.
