How does new firewall rules work?

[BigFreddy]

Hi,

The major new feature in version 26.7 is the new firewall rules and I'm still used to the old way how firewall rules were working. Does anyone know if there is or can recommend any type of in-depth write-up or YouTube video explaining the differences and what's new and how it works now compared to the old way? I tried searching for it on YouTube but couldn't really find much.

Thanks

I found this explanation pretty good: Opnsense firewall rules

Are you planning an initial setup or preparing to migrate? Following the relevant dialogs works with only rare exceptions.

IMHO just the webGUI is different and everything works pretty much the same way, but with added information/clarity compared to the old webGUI :)

Reading the documentation linked in the reply above this one by @passeri should be all you need to know.
