Hello everyone. I've been using NetBSD for a year or so now, as a desktop and on a Pi3. I'd like to setup a firewall on it (you need one, right?) but I have no idea where to begin. I read over NPF and some man pages and a few forum posts here, but I'm lost.
UFW on Linux was really easy to setup, and I found some guides for FreeBSD, but I can't find anything for NetBSD.
Can someone explain it step by step? And talk to me like I'm 10 years old?
