I bought a fortunate 60e a few months ago to play around with. After setting up some vlans, subnets, and firewall rules I am considering just selling it. Without a license you don't even get security updates. So at this point opnsense might be my next firewall to learn on. I was just trying to my hands on what is actually being used by companies.
It would be cool to see companies start offering homelab licenses for people to play around with and get experience before buying into a whole ecosystem.
