I’ve made a tool that can convert your pfsense configuration to an opnsense configuration. It’s not perfect, but it can do a majority of the legwork for you.

You can pull the site via docker:

• docker run --name pf2opn -p 4200:80 -d mwood77/pf2opn

Or use it on the web here:

• https://www.pf2opn.com/
• The conversion happens 100% on your machine; there are no network requests / cookies / or any kind of tracking on the site.

As always, please try the converted configuration in a test image before you apply it to a production environment. If you find any bugs, please reach out.

A raspberry pi is extremely overkill for such a task. You could easily do this with an E-Ink display connected to an ESP32 or maybe an ESP8266. These have about 4mb of memory (depending on what board you buy) and onboard wifi/bluetooth. They cost about $5.

I’ve made the source available, see here: https://github.com/mwood77/pf2opn

Here’s the source - you can clone it and run it yourself if you’d like: https://github.com/mwood77/pf2opn

You don’t need linux, or anything fancy to run containers. If you’re not comfortable using a cli, get Docker Desktop. This way you can ‘see’ and manage your containers in a GUI.

From there, you can then learn about docker’s cli: https://docs.docker.com/engine/reference/commandline/cli/
