Same issue on debian 8.6 (jessie) with kernel proxmox 4.4.24-1-pve under lxc (2).
In this kernel, modules "br_netfilter" and "bridge" compiled with kernel.

# docker network create -d overlay --subnet= --gateway= --ip-range= multihost-network1
# docker service create --name testnginx --replicas 3 --network multihost-network1 nginx

docker Failed joining ingress sandbox to ingress endpoint: error creating external connectivity network: cannot restrict inter-container communication: please ensure that br_netfilter kernel module is loaded
