I have one firewall running pfSense. It stands guard between my
modem and my internal server. I don't understand why the pfSense
box has two NIC's and the mail/web/DNS has only one, but that's
how my LAN guy reconfigured things.
one thing I'm thinking of is to get One fast and lower-power server,
having two jails. One jail would be as-is with mail/web/DNS and the
other jail would be "tao", my main server for years. When I buy
a reasonably fast ThinkPad, it could run Ubuntu and I could
reconfigure my older boxen for emergencies.

They are finally waking up! Especially as their own costs
skyrocket, and as the poor consumers {that's us} start yelping as
our power bills hit the ceiling. It will be at least a few years
though, so for now, yes, it's our responsibility.

And of course these costs are passed along. Borne by not only
the consumer but by the planet. ....

The way I see it, since we {us-[BSD]-geeks} are among the most
savvy folk on the planet, it's make sense for us to be in the
lead on this type of issue. [volumes left unsaid]
