Infrastructure

  In order for the three Coordinating Nodes to communicate securely using a variety of services, a Virtual Private Network will be created to connect the three. While there are probably other ways to configure this, I am configuring the VPN as three pairs of peer-to-peer connections with the following node ids:

      cn-ucsb-1 = Node 1
      cn-unm-1 = Node 2
      cn-orc-1 = Node 3

  As a result, I need an inbound ports opened on the border and host firewalls: 7600 + (source-node-id * 10) + (destination-node-id)

      cn-ucsb-1 → cn-unm-1:7612
      cn-ucsb-1 → cn-orc-1:7613
      cn-unm-1 → cn-ucsb-1:7621
      cn-unm-1 → cn-orc-1:7623
      cn-orc-1 → cn-ucsb-1:7631
      cn-orc-1 → cn-unm-1:7632

Thinking the other way:
      cn-ucsb-1 needs to open ports 7621 and 7631 (#3012)
      cn-unm-1 needs to open ports 7612 and 7632 (#3013)
      cn-orc-1 needs to open ports 7613 and 7623 (#3011)
