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.
