You should create a Management VLAN to access the LTE device from your Network and ether1 as the passthrough Interface ...
Go to Interfaces VLAN, create a new VLAN on interface ether1 with VID lets say 10 and name it VLAN10. Assign an IP address to VLAN10, for example 192.168.10.1/24
Then on the LTE APN settings configure the passtrhough on interface ether1, not on VLAN10.
You dont need any NAT on your LTE device, the NAT will be performed on the Router before the LTE.
On your Router, configure the ether port that the LTE is connected to, and assign an IP address, lets say 192.168.10.2/24
Then from your Local network you will be able to access the LTE 192.168.10.1, but you will need to add a route on your LTE device.
If for example your Local network is 192.168.11.0/24 then on the LTE you must add a route, that when dst-address is 192.168.11.0/24 your Gateway is 192.168.10.2. This is needed, otherwise the LTE won't know how to reach your Local network...
Don't forget to masquerade the interface of the Router that the LTE is connected to and also Update ROS to latest version...

I don't know if you need the second port of your LTE and how you want to use it so i ve not commented on this...
