Port Forwarding SXT Lte - RouterOs 6.46.2

Hi guys,
just bought an external SXT Lte, with RouterOs 6.46.2 . In the last 2 days I tried several times to forward the ports to play online with Xbox Live.
The router address is 192.168.1.1, the Xbox has a static ip: 192.168.1.115
I added both the firewall rules and the nat rules, but the ports are closed and the Nat on the xbox is Moderate.
Here attached the rules and the interfaces. I’m not sure about the interfaces: if i select ether1 i receive an error message: in/out-interface matcher not possible when interface (ether1) is slave - use master instead (bridge)
If i select bridge nothing works…
can anyone help?

I like screenshot but not from firewall.
Please use
/ip firewall export file=export
and uploud this file. You can replace public IP with name: PublicIP.1 etc.

In last screenshot you have strange “In interface” - should be your lte1 interface. Give us export to provide help.

Port Forward works like:
FROM: any internet IP, receive from lte1 interface
TO: Your Public IP and some port’s and protocols on it
Action: DNAT TO: your local server
