Help required: Configuring 2 eth port on a docker host machine

hi, i am pretty new to docker.
i have a machine with 2 nic ethernet port. i configured my docker containers already on eth0, working.

but my boss wants to have another entry point on eth1 (different set of ip, source) to be able to access the same docker containers.

how should i approach this? i read up macvlan and overlay network but they seem different use case.

any kind advise is appreciated. thank you.
