Purpose

This document explains the basic, high-level network requirements for connecting an Pay Plus device to a local network via Ethernet.

The following provides all essential networking, port, and IP requirements for a network engineer to make necessary changes to a host network.  All the following Fully Qualified Domain Names (FQDN) or specific IP address listed below are required for the vending devices to function correctly.

Network Requirements

All connections are initiated from the vending device and the below FQDN, IPs, and Ports need to be open for outgoing bidirectional communication. 

Google Cloud Messaging: For security purposes, the IP address for the Google Cloud Messaging service is constantly changing and is not a fixed address. Also, there is no official publication of the IP addresses. We normally advise against defining IP addresses on the firewall for this purpose. Instead, we suggest either allowing all outbound connections to http & https or defining the DNS addresses as permitted destinations for traffic through the firewall.
