Hi,
In addition to Dan's comments you can also take a look at the following

If you are using tunneling, the traffic will exit out the NIC based on
your physical server's routing table and the destination IP of the
tunnel. For example, if your physical server is tunneling a packet to
a VM on a physical server with IP W.X.Y.Z, the packet will leave
whatever NIC has the route to reach W.X.Y.Z .
