kube-proxy doesn't create DNAT-rules on nodes for services registered on master. everything works fine beside this service-ip-to-pod-ip NATing.

my setup:

kubernetes master: 10.98.99.176/24 (running: api-srv, scheduler, controller-manager)  
kubernetes node1: 10.98.99.136/24 with CIDR 10.116.0.0/24 (running: kubelet, kube-proxy)  
kubernetes node2: 10.98.99.137/24 with CIDR 10.116.1.0/24 (running: kubelet, kube-proxy)  

CIDRs are configured on master via Node.spec.PodCIDR

cbr0-bridge is created on kubelet start.
routing is set up an works.
all fine.

i can ping the kube-dns-container running on node1 from a node2 container via its container ip (10.116.0.2) but not via its service ip (10.0.0.10). i see this icmp-packets moving out on eth0 to default-gw (10.116.1.2 -> 10.0.0.10)

so when i have a look at iptables-save output:

there are DNAT-rules missing for something like 10.0.0.10 -> 10.116.0.2, isn't it?

here the kube-proxy-debug-log-output while starting:

the kube-proxy receives the services but no rules are generate for them (maybe because the api-server does not provide the pod-ips)

here are my additional systemd startup-flags:

docker:      --bridge=cbr0 --iptables=false --ip-masq=false  
api-server:  --service-cluster-ip-range=10.0.0.0/24  
kubelet:     --configure-cbr0=true --cluster-dns=10.0.0.10  
kube-proxy:  --proxy-mode=iptables
