Wap lte kit vlan connection setup

I’ve been trying to figure out how to set up the passthrough in wap lte kit. I would also need a vlan connection not to lose it as described in wiki:
Note, that it will not be possible to connect to the LTE router via public lte ip address or from the host which is used by the passthrough. It is suggested to create additional connection from the LTE router to the host for configuration purposes. For example vlan interface between the LTE router and host.Would someone guide me and help with the commands to setup the vlan.

My intention is to connect (pass through) lte and ether then have the management either from wlan or ether if I manage to create the vlan connection.

Should I detach both ether1 and lte1 from the bridge (how)? Could I still connect to wlan1 and engage passthrough (lte1-ether1) from wlan1? Would the wlan1 still have the same IP, 192.168.88.1?

I created a new apn profile as described in the LTE wiki

[admin@MikroTik] >/interface lte apn add apn=apn1 passthrough-interface=ether1

Then I deleted ether1 from the bridge and set the new apn1

[admin@MikroTik] > /interface lte set lte1 apn-profiles=apn1

After that I could still use the wlan connection and reach the router (using the MAC address) but unfortunately the lte-ether network stopped working.

What went wrong? I could use some help getting the passthrough working.

Run into same problem with vlan:

When enabling the pass-through, all traffic from “host” as identified by MAC will be forwarded to LTE module. Since the naked vlan will inherit MAC from physical interface, it’s traffic will be hijacked as well.

So one needs to change mac of the vlan: https://wiki.mikrotik.com/wiki/Change_MAC_address_of_VLAN_interface
