The original issue was: https://github.com/containernetworking/cni/issues/84 I've added "a fix" for it in https://github.com/containernetworking/cni/pull/149 which then was merged in https://github.com/containernetworking/cni/pull/177 The thing is that "the fix" was incorrect as it was setting 1 on arp_proxy (I really don't recall why) instead of setting it on arp_notify - which was my original suggestion in: https://github.com/rkt/rkt/issues/1765#issuecomment-188776317 Setting apr_proxy can be harmfull and we have already support for sending GratuitousArpOverIface after setting an IP address, so setting any sysctl should not be needed.
