Has anybody had any luck getting LAN Mode to work if the printer is isolated in an IoT network away from your workstation? It doesn’t seem to be discoverable (even with mDNS repeaters) in the slicer, nor does the direct FTP trick seem to be working when the traffic is routed.
Hopefully the definition of LAN doesn’t actually mean the local subnet only.
On the other hand, MQTT appears to be happy routing across networks on my home network.
