Kubernetes version: 1.6.3
I have following interfaces on my vagrant machine.
enp0s3 Link encap:Ethernet HWaddr 08:00:27:ee:32:98
inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0
...
enp0s8 Link encap:Ethernet HWaddr 08:00:27:88:a1:e8
inet addr:10.0.15.11 Bcast:10.0.15.255 Mask:255.255.255.0
...
I have deployed gcr.io/google_containers/kube-proxy-amd64:v1.6.3 on the cluster.

---------
The problem the iptable rule says " DNAT --to-destination 10.0.2.15:6443", it
should be set to "DNAT --to-destination 10.0.15.11:6443" -- the interface.
is there anyway I can force to use 10.0.15.11 instead of 10.0.2.15.
In 1.5.2 Kube version, the IP table rule uses 10.0.15.11.
thanks in advance
