Hello,
We have a single node installation with RDO Kilo release. Network
configuration consist of 2 private networks and one of them is floating.
Networks are routed just inside the node. The problem I`m facing is when I
try to configure the DNAT rules to reroute the traffic/ports to VM.
Initially the traffic to VM works fine until neutron reorders the rules on
top:
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
neutron-openvswi-PREROUTING all -- anywhere anywhere
nova-api-PREROUTING all -- anywhere anywhere
Is there any way I can prevent this or set them with lower priority?
Best Regards,
Kamen Tarlov
