Kernel requires IP_MULTIPLE_TABLES

Good morning,

I’m trying to run BMX6 on a OpenWRT image over a docker container. The installation works fine but when I try to run any BMX6 command it stpps because of something missing related with IP_MULTIPLE_TABLES in the kernel.

Is there a way to solve this? Is the container using the host(Ubuntu 16.04) kernel configuration?
Can I indicate somehow any configuration during run time?

Docker version: 18.06.1-ce, build e68fc7a
OpenWRT image: openwrt-x86-generic-rootfs latest
