I'm realizing that I need a dedicated firewall/router and wifi AP to manage traffic to the services I want to host at home. The old heads give me a resounding "DUH!" for just now coming to that conclusion. They used to just have this stuff and set it up by default so they could run their website or whatever from home.
But I'm learning.
So I'm a little ahead of today's curve on self-management, yet still behind yesterday's.
How far behind is everyone else? They are and will be under complete control, maybe forever.
A larger problem indeed.
