While I have bludgeoned my way through to a "stable" (ish) configuration, I find this device to be incredibly unstable.
Connect via MAC address with WinBox.
Reset with no defaults first:
Run the following:
/system reset-configuration no-defaults=yes keep-users=no
And I immediately lose connectivity via WinBox once the LTE IP is passed through to ether1. I can "see" the new WAN IP address via WinBox discovery, but can no longer connect to the MAC address. Eventually I can't even discover the device in WinBox and have to factory reset it (followed by a no-defaults reset via Terminal).
/interface lte apn set [ find default=yes ] apn=some.isp.com passthrough-interface=ether1
If I load my working configuration (which has passthrough-mac defined), then I can get as far as creating a management VLAN on ether1, but connecting to said VLAN interface becomes inconsistent.
What's the correct order of commands here?
"Working" (but still kind of flaky) configuration:
