As it turned out, this is not enough because inter-node
communication to pods via services doesn't work yet.  You have to
route the service traffic to an interface connecting the nodes.  On
nmcli-based systems (RedHat), this is:

    nmcli connection modify {connection_name} +ipv4.routes {service_cidr}
    systemctl restart network.service

Tschö,
Torsten.
