LtAP LTE Passthrough

Hello,

I have one problem with LtAP LTE Passthrough.
I have mikrotik ccr1009 which eth1 is configured as wan (dhcp client from fiber). On eht2 I want to setup LtAP for backup.
LtAP I have configured and got Internet acces, after which I have ebabled Passthrough on bridge. Only Ethernet is on bridge, but there is no way I can get public IP from LTE network.
LtAP sonfiguration is:

  • APN is configured and can reach Internet, on APN passtrough is set on bridge interface
    WiFi disabled
    Lan Port is in bridge, and bridge has IP from local subnet for administration
    Dhcp is disabled

After all of thet I can’t get IP on eth2 interface. What do I need to configure on CCR so I get get public IP.
I have contract with my GSM provider that I get pulic IP on lte, so I am not behined CGnat.

Thank in advance

anyone dealt with this?
