Sergio,

I have an Ubiquity router which has several external ports. One port can=20
be set as a DMZ with everything passing directly through with no=20
filtering or visible forwarding. That could allow you to connect another=20
router and a whole separate network. So far, I have had no need for it=20
although I came close when I had one port for dedicated telephone service.

I put the web and email on the same VM because originally I only wanted=20
one VM exposed to the outside world. I now have another VM for telemetry=20
(MQTT) and may eventually add a remote desktop controller.
