192.168.234.100 is the IP of the printer, 192.168.234.101 (or others from the subnet) is mine (the laptop)
What ports are open?
322: no idea, might be rtsps, but i cant get the “rtsps://192.168.234.100/streaming/live/1” thing to work. Source: How to access camera on LAN ?(firmware 01.06+)
990: That means you can do ftps://192.168.234.100 (username: bblp, password is the LAN access code)
Port 3000 (TCP)
Port 3002 (TCP)
Tunnel is ssl: unknown service
Port 8883 (TCP) Tunnel is ssl: mqtt → we know that one, its the built-in mqtt broker.
So the TCP 3000 might be documented: Printer Network Ports | Bambu Lab Wiki
