Remembered that I have a little laptop (got it for reading books online).
Just installing Devuan Daedalus on it.
Maybe I could use that in this process - - - - what say you?

Was thinking of using the dns server on the opnsense box (it has a lot
of options - - using, using dnscrypt,
DNS over https, dns block lists were what I was thinking of starting with.

That's one of the possible issues.
I had bought a USB to ethernet dongle - - - - found out afterward that
it was the only version that actually
worked on FreeBSD (most such work well on linux only the one (to date)
on FreeBSD. There is only one RJ-45 port
so that could be a part of the issue but I don't think so.

That's what I'm think is the issue at present as well.

Oh yes - - - that had been the plan. Setup and configure things on the
opnsense box while I was still on the
previous ISP - - - then my radio or POE injector (think it was the
radio) cratered. (I did NOT want to fool with
LTE internet - - - had tried it once a number of years ago and the
usefulness was something between 0 and
non-existent.) That was the beginning of the avalanche. Now I'm trying
to dig my way out - - - its not going too well.

Just checked with the isp - - - level 1 tech - - - should be no
problem, me - - please check, hold for a few minutes,
they weren't too clear, you should be ok, if you have any problems
authenticating when you're adding the second
router - - - call us - - - we should be able to help. So that's
doable. Remembered that I have a little 5 port
switch here - - likely just a 10/100 but that's already only 8 or 9
times faster than previous isp so will be trying that pdq.

If I can get this opnsense box router/firewall working step next would
be to add a SoC running asterisk - - -
thinking openwrt + asterisk but that's from memory but that would be
to move the phone from a landline (will
keep it but under a different number) to VOIP.
Parallel projects would add some few dozen SoCs and ucontrollers but
that would be done by adding a SFF
system with 2 nics and other router in the mix (second router would be
on a 172.16.x.x ) had thought perhaps
of doing a large network including the present but want the added
security in adding a second layer.

So - - - more work to do.

Thanks for the ideas and your time.
