Editing Files on the Firewall

Diagnostics > Edit File contains a file editor that allows editing and creating files on the filesystem of a device running pfSense® software.


Be careful when choosing a file to edit! It is very easy to render the firewall unusable by editing the wrong file or introducing errors into the source code.

Do not use this except under guidance of support or when there is sufficient knowledge to use it without causing unintended side effects.
