I've started building an OPNsense box to replace my enterprise router on similar hardware. I needed more ethernet ports for more zones, but otherwise very similar.
I have lots of complicated rules in my existing router that need to be ported over and testing is going to take a while, but it'll be worth it in the end.
And as soon as it's set up and working properly, Im going to wipe it and restore from a backup. Because I'm the type of hacker who tests my backups! 🤓
