How did you get your users through the tailscale process? I fear the tailscale sign in process is dissuading my potential users.

I wish the questions weren’t mandatory. I am only knowledgeable enough to fairly answer 5 or so of the questions.

If you’re considering building your own firewall, you’ve started down a long path of homelabbing. I’d encourage you to start with a proper setup and allow yourself plenty of room to grow. You want your setup to be extensible, and the firewall is just the beginning.

I’d grab at least a 15U rack and a Dell poweredge R210. Throw in a gigabit nic and install OPNsense. You’ll have room for your switches, NAS, UPS, etc… later.
