How to setup neutron to have ideal NAT path?

Usecase: No public/floating IPsfor instances. Only NATed outgoing traffic. Using linux-bridge instead of OVS.

My use case is a multinode setup, in which each physical device has only one network-interface. Each physical server is interconnected with every other server via tinc-vpn in full-mesh mode.

VLANs over tinc are used for tennant networks. A single tennant with multiple instances on different compute-nodes works fine. Right now, internet access is created with NAT-rules on the physical node. But traffic to internet is always routed through one single compute-node. Access to the internet should always take the shortest path and not be routed through another compute-node or a singele network-node.

Question:

Is there a simple solution for this?

Would a switch to OVS allow that?
