Let's start with the end in mind.
Overview of what I'm trying to solve/answer/improve:


  • I want to be able to safely / securely host web apps on Ubuntu Server that's accessible from the public internet
  • intermediate step would be to just allow segment 1 to access to segment 2
  • I want to be able to contribute to an opensource   blockchain consensus on an ubuntu server
  • future segment 3 has a Kubernetes Pi cluster with control plane and applications web accessible

My first time making a networking diagram and this is my attempt.


This is both a current and future state.  Questions below about what needs to be modified.



How did I get to this diagram?

1.  Segment 1 was quick and simple.
     1. a  when I'm on the Segment 1 wifi broadcast, the Pi-Hole is handles DNS.
2.  Working from home, I found video calls sucked so I built Segment 2
     2. a    Segment 2 I attempted to just use the AirStation as an Access Point  (? may have misused the term) but the couldn't figure get it successful, so I now just switch to a different broadcast network.  I get the lower latency and it works fine.
     2. b  I deployed a Docker container on the Segment 2 running Nginx web server ...
         2.b.1  I understand that I can only access localhost from the wifi connection on the AC1750 modem
         2.b.2  I don't understand, why -- when I'm on the segment 1--  can't I access the Nginx app via port address ?
