No. Napster Station only makes outbound connections. Nothing listens on the device, and no inbound firewall rules or fixed IP address are needed.
Remote support also works over an outbound connection that the station keeps open, not over a port it exposes.
Firewall summary
- Outbound TCP 443 to the required domains (this alone covers everything).
- Optional: outbound TCP 8883 to
*.azure-devices.net, which is slightly more efficient for the fleet connection. - No inbound rules.
