---I just received mine, so haven't done this yet....but will try, as soon as I get more acquainted with the device in general.
This is how I think this is going to work:
- as usual wipe the complete configuration, as quicksets et al. will leave some ugly things behind (system - reset config - no default, no backup)
- then configure the device as a standard LAN device (create a bridge and add eth1, add ip address from your main router)...
- enable VLANs (
viewtopic.php?f=13&t=143620) and should you have a management VLAN other than PID=1 move the device (bridge) into it.
Edit: OK, this will not work, as lte1 interface is not L2...you cannot assign VLANs to it, only to ether1..maybe you only can create a management VLAN and anything not in a dedicated (management) VLAN on ether1 will end on default, hence on lte1...need to investigate further
(- then add and enable the LTE-VLAN ID on the lte1 interface and bridge and on your main router as well
- add passthrough...it should then be linked to the VLAN-MAC of your main router of the other side of the VLAN)
....just make sure that you have access to the main link from a computer running winbox, in order to be able to access the device in MAC, legacy mode.
Maybe do all this in your lab, before you move it above ground
