Hello Volodymyr, You have two options: 1. When you create your VIP, simply put in your external network as the vip-subnet-id or vip-network-id. This will allocate a public IP to the VIP. 2. Use neutron to assign a floating IP to the VIP address of the load balancer. From your example, let's say the VIP address of lb1 is 10.0.0.10 on the nbt-subnet with port ID 7e11e63e-7dcb-4b2c-835e-f5cd7ca79acf. You would use "openstack floating ip create --port 7e11e63e-7dcb-4b2c-835e-f5cd7ca79acf external". This will assign a floating IP to the VIP address.
Option 1 will have better performance as there is no NAT occurring like there is with a floating IP.
