The download process for older pfSense versions differs from the main page, which now focuses on the latest release via a dedicated installer. Here is exactly how to get the pfSense-CE-2.5.1-RELEASE-amd64.iso.gz file.
Insert the USB drive into your target hardware (or attach the ISO to your VM) and boot the system. Select on the copyright notice screen. Select Install pfSense and press Enter. Choose your Keymap settings (default is usually fine).
If you encounter difficulties with the official store or need to find an older version like 2.5.1, you can use one of the official, public mirror directories. Netgate maintains an old/ directory on some mirrors containing previous releases.

From here, you can explore the myriad of additional features, such as setting up firewall rules, creating VLANs, configuring OpenVPN, or installing packages like (for ad-blocking and IP reputation filtering) or HAProxy (for advanced load balancing).
It is highly dangerous to download firewall software from unverified third-party sources. A firewall is your network's first line of defense. A modified ISO could contain backdoors, keyloggers, or rootkits that compromise your entire network security. If you cannot verify the checksum against the official Netgate documentation, do not use the file.
