First, I want to thank all those involved in developing and supporting OPNSense. I've been using OPNsense now for almost a year and am quite appreciative of it and those who have developed it and have helped, and are helping, me understand better on this forum.
Next, I wanted to share with you a freeware tool that I wrote and have found useful when using OPNsense.
Basically, it works as a 'reading guide' helping you to see more clearly which rule you are working with on the screen.
I've posted a short (3 minute) video that shows this in action. If you're interested, you can watch it here:
