I need some help of figuring out how to re-arrange or deal with my current home network setup as things grow and expand.
Until recently I had an older AMD machine with a 3 drive Raid 5 setup in my house to serve up some basic websites, a minecraft server (for the kids), MythTV, and to act as a repository for my media.
A few months ago I was gifted an i3 computer with 12 GB of ram that I had hoped to migrate all my server based things to. I setup ESXi and installed some Virtual machines, but the i3 and the MB do not support VT-d which means my Raid array and mythtv need to stay housed in the old AMD box.
I also, for some reason setup MQTT on my old server and since it’s working, I have some devices already pointed at that broker, and I’m lazy, I’m hesitant to move it.
So with the background out of the way, I would like to setup Let’s encrypt on my VM (in docker), setup SSL for my FQDN which has elements spanning multiple machines. If I proceed with this, how can I encompass MQTT and Apache on the AMD machine with the cert from lets encrypt?
Do I want to use a Let’s Encrypt cert for MQTT (which I use with Zanzitto on our mobile devices). Should I setup a second MQTT broker for the inside the network elements, and bridge that second Broker with the first that only does Zanzitto and other outside the network elements?
