Each printer needs to be accessible by the Aggregator on a printer-specific port. Those ports need to be forwarded per printer. Firewall rules need to be adjusted.
Collecting all IP addresses and ports might be harder.
Security Considerations
The traffic between the Aggregator and machine depends on the machine manufacturer. Not all manufactures use secure channels, we can therefore not guarantee that the connection is always secure. Hence we recommend to deploy the Aggregator inside the machines' network.
The traffic between the Aggregator and the 3YOURMIND Agile MES is encrypted with TLS/SSL.
