Mikrotik and LTE USB modem

Hello, I have got modem Huawei K5160 into USB and RB750. I need to have public IP address from provider on interface in MK, because I need make connect to MK. When I am insert modem to PC with Windows 10 then public IP is on interface. When joined modem into MK, is automaticaly creating LTE interface with DHCP Client, and LTE interface is assigned IP from private subnet as (192.168.9.0/24). Is there any chance how passthrough public IP to interface on MK?
I tested passthrough and I assigned interface ether1 and mac address from ether1, then am assign manually IP address and route on lte interface. But nothing.

I have progressed according to
https://wiki.mikrotik.com/wiki/Manual:Interface/LTE#Passthrough_Example example 1 and after assign manualy ip address on interface ether1 or lte but nothing. I tested create dhcp client on lte and then on ether1 but again nothing.

Nobody know?
