Openstack 13 Floating IP not reachable & Cinder Netapp Integration

Hello folks,

can't access the vm with attached floating ip.
But I can ping/traceroute the router-gateway from the project-router.
The security group is set to allow everything (every protocol from everywhere) from ingress and egress.

We use a separate VLAN for our floating-ips and we configured it the same way as in our staging environment.

the router from the admin-project (where there VM is located) has the "router-gateway" with the ip 10.10.1.1 - which is actually reachable via ping/traceroute from director and other machines (like controller oder compute nodes)

the VM gets the floating ip 10.10.1.130 (correctly associated) which is not pingable/traceroute-able from anywhere.
The Status the floating ip is actually down (for example the Status of the floating ips in the staging environment is "Active").

Its important to know that our staging env is running on OSP12 and our production env is running on OSP13.

thanks
