Doesn’t matter. Publised ports on swarm services always bind to 0.0.0.0 - wether you like it or not. Plain container or docker-compose container additionaly allow to bind published ports to a host ip.

By any chance, do you use Debian Buster? if yes, see iptables - Debian Wiki on how to switch back from nftables to iptables.
