Installing and Upgrading

Hardware from the pfSense Store is pre-loaded with pfSense® software. To reinstall pfSense software or to install it to other hardware, download an installer image as described in this chapter.


Hardware pre-loaded with pfSense software from commercial vendors other than the pfSense Store or authorized partners must not be trusted. Third parties may have made unauthorized, unknown alterations or additions to the software. Selling pre-loaded copies of pfSense software is a violation of the Trademark Usage Guidelines.

If pfSense software was pre-loaded on third party hardware by a vendor, wipe the system and reinstall it with a genuine copy.

If something goes wrong during the installation process, see Installation Troubleshooting.

This chapter also covers upgrading pfSense software installations (Upgrading an Existing Installation) which keeps them up-to-date with the latest security, bug fixes, and new features.
