Hi Joel,

Good to see you again!

On my next router, (probably OpenBSD/pf), I'm going to block all IPV6.
I enjoy that the badguys have to jump through one more hoop (NAT) to
hit me where it hurts.

I'm not an authority on firewalls and routers, but I'm going to try
hard to pass only a very few IP addresses on my LAN, and put the Wifi
on a third network card.

In my opinion, IOT (the Internet Of Things) is for the most part an
abomination. I don't want my thermostat on the same subnet as my LAN.
