pfSense Installation and Configuration

1. First visit the pfSense download page and select your computer architecture and platform. Here I’ve chosen “i368 (32-bit)” as my computer architecture and platform as “LiveCD with installer“, but in your case it would be different, make sure to select and download correct architecture for your system.

2. After selecting the architecture and platform, you will get a list of mirrors to download, make sure to select nearest mirror link to download the image from there.

3. After download completes, the downloaded image must be burn to an CD/DVD media as an ISO image before we start using it. You can use any CD/DVD burning software to burn the image to CD/DVD media.

If incase, you don’t have an CD/DVD drive, you can use Unetbootin tool to create a Live bootable USB media or if you don’t want to follow all these procedures, just go the pfSense download page, there you will get pre-created bootable pfSense images for you USB media, just go there and grab the “Live CD with installer (on USB Memstick)“. Don’t forget to select USB console type before downloading…

4. Now switch on or reboot the target machine, place pfSense CD/DVD or USB stick and set the BIOS options to your booting method (CD/DVD or USB) according to your choice and choose the boot options by pressing a keyboard function keys, usually F10 or F12, pfSense will start booting….

5. As the pfSense starts booting, a prompt is displayed with some options and a countdown timer. At this prompt, press 1 to get install pfsense by default. If we don’t choose any option it will start to boot option 1 by default.
