The solution is to create another network provider. do the necessary changes (configuration files) - Launch an instance connected to the VLANi - Attach an interface to link the instance to the new created network - add a second floating ip (add second floating ip to an instance do not tey to add a floating ip address from Horizon it does not allow you to do that. -add a second routing table to be able to ssh the instance (configure multiple Floating IP for one instance) - Sometimes you need to reduce the mtu (maximum transport unit) of the instance NIC (in case when the ping works but the ssh won't)

sudo ip link set mtu 1400 dev NIC_name

This configuration is tested and it works for me. Hope this help someone in the future
